As we all know, the O-ring is made of a variety of rubber materials, and the rubber material of Haide Paike is fully covered. The commonly used O-ring materials are nitrile butadiene rubber (NBR), hydrogenated nitrile butadiene rubber (HNBR), EPDM, fluororubber (FKM/FPM), fluororubber (F-SIL/FVMQ), silicone rubber (SIL/VMQ), rubber. Neoprene rubber (CR), perflurane rubber (FFKM), tetrapropyl fluoro rubber (AFLAS), acrylic rubber (ACM) and so on. Faced with so many materials, how do we choose the right material O-ring? We share with you the advantages and disadvantages of different materials of O-rings, hoping to help you with O-ring material selection.

Chloroprene Rubber is referred to as CR, and chloroprene rubber is also called chloroprene diene. The vulcanization hardness of chloroprene rubber ranges from 30℃ to 90℃. CR is also used for the production of O-rings or rubber products.

Advantages of Chloroprene Rubber (CR) O-rings:

1. Chloroprene rubber O-ring has excellent aging resistance. Due to the role of chlorine atoms in electron absorption and masking, chloroprene rubber has superior aging resistance.
2. Chloroprene rubber O-ring can release a large amount of hydrogen chloride when burning, but carbonization does not delay combustion, and good self-extinguishing. Therefore, the fire resistance of neoprene rubber is the best in general rubber.

Disadvantages of Chloroprene Rubber (CR) O-rings:

1. Chloroprene rubber O-ring has poor low temperature resistance and is prone to crystallization hardening at low temperatures.
2. Chloroprene rubber O-ring storage stability is poor, neoprene rubber is easy to harden and depreciate during storage.
