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.

Fluororubber, FKM, VITON and FPM are short for fluororubber, which first appeared in 1948 and has a history of more than 70 years until 2020.

Advantages of fluororubber (FKM) O-rings:

1. Fluorine rubber O-ring high temperature resistance, high temperature resistance is one of the most prominent characteristics of fluorine rubber, high temperature resistant material must be the choice of fluorine rubber material.
2.Fluororubber O-rings are resistant to a variety of chemical agents, and fluororubber itself has outstanding resistance to aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, fuel oil, oil and many other organic liquids. In addition, it also has chemical corrosion resistance, flame spread resistance, oxidation resistance, ozone resistance, weather resistance. And with the increase of fluorine content of fluorine rubber O-ring, the performance of resistant medium will continue to improve.

Disadvantages of fluororubber (FKM) O-rings:
1.Fluorine rubber O-ring cost is high, because fluorine rubber O-ring of fluorine rubber raw material cost is much higher than nitrile rubber o-rings, so the use of fluorine rubber O-ring cost is also N times of ordinary rubber material.
2.Fluorine rubber O-ring low temperature resistance is poor, the standard fluorine rubber material itself low temperature resistance is poor, if you need low temperature resistance -40℃ it needs to develop special low temperature fluorine rubber raw materials.
