O-rings are quite common, and they are also called sealing rings, but many people don't know that O-rings actually have many kinds of materials, and the advantages of different materials are different. Let's look at the advantages of several common materials?

1 fluorosilicone rubber O-ring, which has the common characteristics of silicone rubber and fluorine rubber, can effectively resist the corrosion of oxyfluoride compounds, and has good fusion resistance to oily substances such as gasoline. It is suitable for high-precision industries such as aviation. Of course, it is not suitable for automobile industry.

2 butyl rubber O-ring, which is one of the most common O-rings, is characterized by high temperature resistance, good adhesion, good air tightness, not easy to conduct electricity, can be directly exposed to the air, not easy to oxidative aging, long service life, but poor oil resistance, not easy to use with kerosene and gasoline.

3 hydrogenated nitrile rubber O-ring has excellent corrosion resistance, extrusion resistance, toughness and strength. It is suitable for vehicle engines, intelligent refrigeration equipment and washing instruments.

4 cyano butadiene rubber O-ring, which is widely used in various industries with low cost. It can be used in other places except for polar solutions such as ozone and ketone nitrohydrocarbons
