Problems solved by technology

[0002] Sealing ring sealing is an important form of automobile static sealing. There are 100-400 sealing rings used in automobiles. The modern automobile industry has put forward higher and higher requirements for seals. These sealing rings can seal the liquid inside the car. With the role of gas and to prevent the intrusion of external rain and dust, all kinds of rubber sealing rings for automobiles have the functions of high and low temperature, wear resistance and aging resistance during work, and require high hardness and good tear resistance. Rubber materials and sealing structures are severe tests; sealing ring materials prepared with traditional formulas can no longer meet the increasingly high requirements for automotive sealing
