Wansheng Coupling's coupling elastic ring is usually made of polyurethane and rubber, and in rare cases, it is made of oxford steel.

Polyurethane coupling elastic ring has excellent abrasion resistance, oil resistance, tear resistance, chemical resistance, high strength, but the heat resistance of polyurethane coupling elastic ring is poor, easy to soften at high temperatures, decomposition, so that the mechanical properties of the sharp decline, long-term use of the temperature can not exceed 80 degrees Celsius.

Nitrile rubber (NBR) is a kind of synthetic rubber made of butadiene and acrylonitrile ****polymerization, it has excellent oil resistance, good abrasion resistance, good elasticity, and it can be used for a long period of time in 120 degrees Celsius in the air or in 150 degrees Celsius in the oil.
