DOP's largest application industries are PVC film, PVC artificial leather and PVC wire and cable, these industries DOP consumption, accounting for almost more than 70% of DOP consumption. With the introduction of overseas environmental regulations, PVC wire and cable began to appear the trend of decline in the amount of PVC, but in PVC film and PVC artificial leather, the actual impact of environmental regulations is not very big. PVC film: PVC film using calendering, casting, coating and scraping, blown film and other machinery and equipment production. PVC calendering machine investment is large, equipment investment in 10 million to 20 million yuan a production line, generally produced in Taiwan, Japan or Germany. Blown film machine production of blown film mainly do mattress packaging film and other low-grade film, a blown film machine investment of about several million. There are various types of film. There are transparent film, colored film, light box film, printing film, blown film, protective film, etc. Hundreds of kinds of PVC film more typical customers, including shower curtains, raincoats, tablecloths, light box film, blown toys, suits and quilt bags and so on. However, it is worth mentioning that there are few enterprises in Guangdong Province to produce agricultural film, there is an agricultural film manufacturer in Dianbai, with an output of about four thousand tons per year. Artificial leather: Guangdong Province are scattered throughout the PVC leather manufacturers. Production using calendering production line and coating and scraping production line mainly. The use of calender production of PVC leather overwhelming advantage, and the use of scraping line production of PVC artificial leather is relatively small. Scratching lines are molded in a single pass, while calenders produce plastic that is later laminated to the backing. Scraped leather is said to have a better surface finish. Calendering lines can use a lot of recycled material, while scratching lines cannot. The scraping line cannot make harder leather, while the calendering line cannot make softer leather. However, the investment of the scraping line is much lower than that of the calendering line. The investment of an imported calendering line is tens of millions, while the investment of a scratching line is in millions. In order to reduce the cost, there are also some factories manufacturing half-PU artificial leather, the surface layer using PU, foaming layer with PVC. artificial leather is mainly used for sofa leather and bags with leather. Shiling Leather Market in Huadu District of Guangzhou City is the main leather distribution center in China. Shiling's radiation ability is very strong, in recent years the foreign leather factory and downstream leather leather products factory has to shiling concentration trend. Huadu leather factory although more concentrated, but because of the large number of recycled materials and soybean oil, DOP is not much. Domestic leather factory is still to low-grade artificial leather is mainly, sales rarely and bags factory with, directly sold to the leather market door (stall). Few companies can manufacture automobile leather for high-grade cars. High-grade car PVC synthetic leather, to use DIDP, 911 or larger molecular weight plasticizer. The so-called automotive leather generally produced and sold in South China actually refers to the seats of domestic brand cars. Most of the film, leather and decorative sheet manufacturers for domestic sales in the Pearl River Delta originate from Gaoming or Foshan. It is rumored that there used to be a Taiwan-funded factory that could supply seat leather to local Japanese automobile factories in Guangdong, but now it has suspended its operation. At present, the Japanese joint venture automobile leather, still have to import. Wire and cable: PVC wire and cable pellets are generally extruded from a single-screw machine or twin-screw machine, generally by the pellet factory specializing in the production of pellets, and then delivered to the wire manufacturers. Wire pellet production equipment is relatively inexpensive, less tens of thousands, hundreds of thousands of a production line, the big ones only need to invest millions. DOP is mainly used for electronic cables, computer cables, telephone cables, network cables, audio cables and power cables these 60 degrees of low-temperature wire and cable pellets. Export wire and cable pellet factory concentrated in Dongguan, Shenzhen, domestic sales in the Foshan area. The Pearl River Delta engaged in the production of bonded wire and cable pellets, mostly from the Wantai system. The largest factory, at its peak, can produce 3,000 tons of PVC pellets. Medium-sized pellet factories, the output of 500 tons to 1500 between. Taiwan-based pellet factory collection time factory, slow return of funds. The longest there are up to half a year collection period. In the spring of 2006, Houjie a building wire factory closed down, the pellet factory tightened the number of payment period. But there are still 30 days to 60 days of payment period. Originally, some rubber wires will also add DOP or DINP, with the introduction of environmental regulations, some rubber wire factory has stopped adding DINP. PVC pellets are only one kind of wire materials. Other materials, such as PVC, PE, PP, PA, rubber and Teflon, can be used as the outer insulation of the wire. Teflon is mainly used to produce high temperature resistant wires (e.g. electric iron wires). DOP is suitable for producing 60 degree wire, DINP is suitable for producing 75 degree wire, DIDP is suitable for producing 90 degree wire, TOTM is suitable for producing 105 degree wire. In practice, some manufacturers use a mixture of DIDP and TOTM to produce 105 degree wire. Shoe materials: outsole of low-grade shoes, middle layer of mid-grade shoes, and low-grade flip-flops. PVC for the footbed portion of leather shoes is made primarily from recycled materials and uses a lot of fillers. DOP is also used in a large number of rain shoes, and DBP is used in rain shoes sold in China, with Pingzhou and Houjie being the main shoe material distribution centers. Oxford cloth: Oxford cloth is actually very simple, on top of the cloth coated with a layer of PVC plastic, waterproof. All can be produced with soybean oil or other oils, but the elasticity and feel is not as good as DOP. a lot of waste materials. A lot of Oxford cloth is used as the lining of bags. The main market of Oxford cloth is also in Shiling, Huadu. Gloves: The production of PVC gloves is different from other dry PVC products, using wet dipping. Generally there are production of medical gloves and labor protection gloves. Medical gloves are dipped in copper molds, and labor protection gloves are made by attaching a layer of PVC adhesive to the outside of the fabric gloves. Guangdong has a medical glove factory, other large glove factories in East China and North China; labor insurance glove factory is smaller, Guangzhou and Gaozhou have such manufacturers, export-oriented. Anti-skid pads: Anti-skid pads and foam pads are one of the fast-growing DOP industries in recent years. In the Guangdong region now has nearly ten enterprises production. Distributed in Guangzhou, Foshan, Dongguan, Zhuhai. Larger anti-slip mat factory, the monthly use of more than 200 tons. Anti-slip mat because the unit price is currently higher, mainly export-oriented, the United States is the main export destination of anti-slip mat. The domestic market is mainly in Yiwu and Xinjiang. Toys: The toy industry was initially the main use of DINP industry. Later, with the price of DINP and DOP close, and the revision of the European toy industry regulations, the amount of DINP used in plastic toys fell very quickly. Especially in 2006 and 2007, the toy industry suffered a devastating blow, the amount of DINP used in toys is less and less, exported to Europe's toys, almost no one uses DINP. but the domestic plastic toys are still using DOP. the development of molds and staff wages is the main cost of the toy industry, while the cost of raw materials accounted for less than 20%, so compared to other industries, the toy industry is the main use of DOP/DINP. Therefore, compared with other industries, the toy industry is relatively insensitive to the price of DOP/DINP. In 2007, the toy industry was seriously affected by the environmental protection regulations from abroad. Edge Banding: PVC edge banding is also one of the industries with rapid growth of DOP usage in recent years. Medium and low-grade sealing strips used in the furniture industry, such as tables, doors and windows of the seal, cabinet roll door accessories, hospitals, collision handrails, office screens and so on. High-grade edgebanding is used in automotive industry, such as soundproofing at automotive glass. The DOP consumption of edge banding enterprises is generally around 10 tons. Unlike other industries that focus on PVC, edge banding companies are generally smaller and produce ABS and rubber products at the same time, called rubber and plastic companies. Most of the edge banding companies in Guangdong originate from the Shuotai system and the Quanyi system. PVC Aluminum-Plastic Pipe: PVC pipe is inserted into an aluminum pipe to make an aluminum-plastic pipe. Used for hot water pipes to increase pressure resistance. The original sales of aluminum-plastic pipe is not bad, now because of the aluminum-plastic pipe itself, DOP in this industry has a declining trend of use. PVC hose: PVC hose is mainly used for ordinary water pipes, gas pipes and road and bridge lighting cover pipe (such as overpasses on both sides of the road lighting pipe cover) and so on. The production of such products, mainly small factories. Lighting materials: lighting DOP usage is also considerable, the main use in Zhongshan and Foshan. LED shell with PVC to do, we need to use a lot of DOP, Christmas lights now switch to LED light, reducing the amount of DOP in the wire and cable, but increased the amount of light fixtures. The largest lighting factory can use more than 700 tons of DOP per month. Floor Leather: Floor leather is also produced using calendering machines. The factories are located in Foshan and Guangzhou. Floor leather is mainly sold to Southeast Asia, South Asia, Africa, Middle East and other economically underdeveloped areas. Carpets, mats, mats: PVC carpets? It is those red "Welcome" ones which are put at the door. It can be imagined that the volume is still considerable. However, this kind of manufacturers use a lot of recycled DOP, calcium carbonate and other fillers, and a lot of DBP. Black or dark-colored cover tiles, and now even all with DBP. car mats, there is also the use of fully transparent PVC foot mats. Foshan has a larger. Wigs: wig manufacturers, few heard of in southern China. Mainly in northern China. Wigs are used for human wigs and toys (dolls). Conveyor belts: Conveyor belts are also made of PVC plastic. The market is mainly in the coal mine production area. Shandong's conveyor belt enterprises are concentrated. Automotive chassis sealant: Four major international companies monopolize the PVC plastic chassis sealant for automotive chassis. These companies are located in various automotive industry clusters near, such as Shanghai, Northeast and Guangzhou. Japanese cars a car chassis plastic coating volume is generally about 2-3 kilograms. For German cars, the chassis plastic coating volume is 7-8 kilograms per car. The amount of DOP used in this industry can be calculated from the monthly output of automobile companies. In addition, small workshops also produce this sealant, but it is not easy to find such customers. Inks and Coatings: Several large international companies use DOP, DINP for coatings to change certain properties of the coatings. For example, one of the world's largest suppliers of wood furniture paint. DOP is also added to inks, but in smaller quantities. Mostly for barrel customers. Flavors and fragrances: Flavors and fragrances also use DOP, DINP, DIDP as additives, but the amount used is very, very small compared to other industries. Fire hose: Fire hose linings are usually rubber or plastic. Because the unit price of rubber is expensive, and the quality of heavy, fast aging, in the past two years appeared in the use of PVC plastic lining fire hose. South China's such enterprises are very few. Wallpaper: Few people will know, in fact, wallpaper is also made of PVC and DOP. Guangdong Province has the largest wallpaper manufacturer in Asia and some small wallpaper factories. With the development of the paint industry, wallpaper in the decoration gradually lost its advantage, these wallpaper enterprises become very poor, production and sales are decreasing, the use of DOP is also decreasing. Label labeling Guangzhou and Dongguan distribution of a number of manufacturing PVC soft label labeling of small factories and family workshops, because the demand for DOP is small, mainly with traders to take the barrels of goods, generally not for the attention of DOP factories. the proportion of DOP in the formulation of a larger proportion of more than 50 Pa. Soft labeling stickers are generally used to make leather bags, leather cases on the logo, jeans and other clothing above the soft logo labels and so on. These factories are also distributed around the luggage factory. Usage is generally a few tons a month, like toy factories, personnel wages and mold development is the main cost, the cost of raw materials accounted for only about 20%. It belongs to labor-intensive industry, the label factory which uses about 2 tons per month, the number of employees can be up to one hundred. Plastic Pigment Plastic pigment companies usually use DOP or DINP as the carrier of pigment. The monthly usage of DOP in larger plastic pigment companies is around 50 tons. Plastic pigment companies in South China are growing fast in recent years. PVC placemats, tablecloths, lace PVC tablecloths and placemats are usually printed from PVC transparent film, but there are also PVC tablecloths, placemats, coasters and lace that are directly molded with PVC and DOP in one time. These tablecloths, placemats, coasters and lace are usually ironed with gold and silver edges and are mainly sold to the Middle East, Russia and Africa. There are about three factories in Guangdong making openwork lace placemats and one in Shandong. There is one factory in Shandong, and the DOP usage is about 20 tons per month. Christmas Tree The factories producing Christmas trees are generally larger. Both the leaves and the trunk of the tree can be made of PVC. Calendering machines are also used. There are large Christmas tree manufacturers in Dongguan, Guangzhou and Shenzhen, all of which are Hong Kong-funded. Products are exported to Europe and the United States. Christmas tree factory in Dongguan, the use of 200 tons per month. Shenzhen's Christmas tree factory, said to have reached 20,000 employees. Shutters Shutters manufacturers, generally smaller, the amount of PVC powder used in the amount of about 50 tons per month, with DOP about 4 tons per month. The PVC blinds sheet of the shutters, PVC plastic rail, are used DOP, but due to the hard texture, the amount of DOP is small. It belongs to trader customers. Polyether, also known as polyethylene glycol ether, is a synthetic oil with the largest sales volume. It is a linear polymer made from ethylene oxide, propylene oxide, butylene oxide and tetrahydrofuran as raw materials, ring-opening homopolymerization or **** polymerization under the action of a catalyst. As polyether has many excellent properties, coupled with polyether raw material epoxy alkane for petrochemical products, inexpensive and easy to obtain, so the scope of application is constantly expanding, and is now mainly used for high temperature lubricants, gear lubricants, brake fluids, flame-retardant hydraulic fluids, metalworking fluids, compressor oils, refrigerator oils, vacuum pump oils and so on. High temperature lubricant. Good viscosity temperature performance and the characteristics of not coking at high temperature. So that polyether can be used as a lubricant material for high temperature gears, chains and bearings in glass, plastic, textile, printing and dyeing, ceramics, metallurgy and other industries. Gear lubricant. After adding some anti-wear or extreme pressure additives in polyether, it is an ideal gear lubricant, which is used in worm gear pair, closed gear and automobile reduction gear of large and medium power transmission to reduce gear wear and prolong the oil change period and overhaul period. Metal working fluid. Due to the water-soluble, oil-soluble and inverse solubility of polyether, it is mainly used as cutting fluid and quenching fluid in metal processing fluid. When used as cutting fluid, cooling, lubrication, no precipitation and foaming tendency, penetration is also good, most of the metal does not corrode, less affected by the water quality and water hardness, so it is an excellent metal cutting fluid. Grease base oil. Polyether can be used as grease base oil, mainly used in the production of brakes and clutches with grease, hydrocarbon solvent-resistant grease, greater than 300 ℃ high-temperature fixed bolts, chains with high-temperature friction with grease and instrumentation machinery with grease and so on. Among them, when used in automobile brakes and clutches, its main advantage is that it has good compatibility with the rubber parts therein and the braking fluid and excellent antioxidant property. Heat-setting machine oil. Printing and dyeing and plastics industry in the use of heat-setting machine and stretch stenter between the chain and the rail is high temperature, high speed sliding friction, the requirements of the lubricant has a good high-temperature oxidative stability, as well as less coking, lubrication and other properties. Compressor oil, refrigerator oil and vacuum pump. Because polyether has good viscosity and temperature performance, low temperature fluidity, oxidative stability and lubricity, small solubility for hydrocarbon gases and hydrogen, and good compatibility with Freon gas, so it is very suitable for hydrogen, ethylene and natural gas compressor oils, as well as refrigeration oils and vacuum pump oils.
