The domestic technology of PVC sports floor is still immature. In order to produce environmentally friendly PVC sports floor, at least the bonding process of PVC sports floor should be solved first. Originally, PVC materials did not contain formaldehyde. Due to the immature production technology of domestic PVC sports floor, glue is used for bonding during processing and production, so the PVC coiled sports floor in the production area contains harmful gases such as formaldehyde, so the domestic PVC sports floor is not environmentally friendly.
In addition, most domestic PVC sports floors are sold in the name of foreign brands, "hanging sheep's heads to sell dog meat". The PVC sports floors that truly meet the requirements of environmental protection mainly include Korean LG sports floors, French Fu Jie sports floors, Japanese Younex badminton floors, Italian Meng Duo sports floors, Hungarian Jiabao sports floors, etc., all of which have passed the German DIN quality certification. As far as we know, domestic brands and other PVC sports floors with foreign brands have not passed the DIN quality certification in Germany, and only sports floors that have passed the DIN quality certification in Germany can be used in international competitions.
For example, the LG sports floor in South Korea is a special floor for the World Table Tennis Championships and the National Volleyball League. The sports floor in Fu Jie, France is the special floor for all previous Olympic Games and World Table Tennis Championships, and Younix, Japan is the special floor for all previous world badminton competitions and Olympic Games. The Italian Mondo sports floor has also passed the floor for the World Volleyball Competition many times.
In addition, PVC sports floor can only be used indoors and is not suitable for outdoor use. I can tell everyone in charge that except for the above brands, other brands of sports floors are not environmentally friendly, but if the price is cheap, of course, the price of domestic floors that have not passed DIN certification will be lower, but the sports floors of LG in South Korea are not much higher than those of domestic brands (except professional ones).
Most of the domestic PVC sports floors are OEM products, and a few are produced by themselves. Domestic brands of PVC sports floor are also divided into high, medium and low. The price of low quality is only 30 yuan/m2, and most of good quality is 60 yuan/m2 (ex-factory price). The imitation Korean LG sports floor is very high.
