PVC rubber seal trademarks are mainly plastic products made of plastic products made by dropping liquid materials into molds through plastic drip process, heating, baking and cooling for a period of time, and finally pouring molds.  The main components of PVC rubber seal are DNP oil, PVC powder, stabilizer, soybean oil prepared into liquid state silicone trademark and PVC rubber seal trademark the main difference is that the material feel is different, silicone high environmental protection coefficient, can be measured in the European Union, PVC rubber seal smell is strong, environmental protection coefficient is not high, it is more common in the domestic market.
