How much is natural rubber a ton?
Hevea brasiliensis originated in the Amazon river basin and is now planted in more than 40 countries and regions. Natural rubber is an elastic solid made of natural latex collected from rubber trees through a series of processing procedures.
Thailand, Malaysia, Indonesia and a few other countries supply natural rubber to the international market. However, the United States and Japan, which are big users of natural rubber, rely entirely on imports. China is also the second largest importer of natural rubber in the world, and its influence on international rubber prices is also relatively direct.
Among them, the price of natural rubber in Malaysia, Indonesia and Thailand is about 7000~ 12000 yuan per ton. The price of rubber in Japan is around 20,000 ~ 35,000 a ton.
The price of 20 15 natural rubber in China is about one ton in 1200 yuan, and in 20 17 the price of natural rubber is about one ton in 16350. The price of first-class natural rubber in Yunnan entered the "40,000 era" for the first time, with an average price of 40,097 yuan/ton, of which the most expensive Eucommia ulmoides rubber is 43,000 yuan.
What are the advantages of rubber?
1. High-low temperature resistance: The creep relaxation change of products at high or low temperature is one of the conditions to distinguish the quality. Rubber products are solid elastomer materials, which will not change physically at normal room temperature, but when the temperature exceeds 100℃, the products will creep except some metal rubber products, thus affecting the use. Therefore, in the high-temperature or low-temperature working environment, the correct choice of rubber products can maintain its reasonable service life and work efficiently.
2. Safety requirements: According to food requirements, when selecting rubber products, we should pay attention to whether the products need to touch food or directly enter the mouth, such as pacifiers and milk bottles. In terms of medical requirements, because of the need to seal highly toxic chemicals, safety is more required, and for volatile liquefied gas, it is required to have high acid and alkali resistance and flame retardancy. Such as medical rubber products, drug containers, etc. In the field of petrochemical industry, it is also necessary to meet the requirements of fire prevention and high temperature resistance of rubber products. For conveying equipment, not only high temperature resistance is required, but also high working pressure is required.
3. Economic benefits: Now many rubber products are made of various kinds of rubber, which are low in cost and meet the requirements. However, when selecting rubber products, it is necessary to consider whether it will cause material loss, economic consequences caused by damage and other losses. Therefore, in addition to selecting products according to demand, it is necessary to comprehensively consider its cost performance.
In addition to the above advantages, natural rubber has excellent resilience, insulation, water resistance, plasticity and other characteristics, and after processing, it also has the advantages of oil resistance, acid resistance, alkali resistance and wear resistance, so natural rubber has a wide range of uses. From rain boots and warm water bags used in daily life to airplanes and tanks used in national defense, even high-tech products such as artificial earth satellites are inseparable from natural rubber.
