The Compression Ratio of O Ring, O-Rings, O Rings And Rubber O-Rings

Hardness and materials decisions O ring, o-rings, o rings and rubber o-rings the compression ratio. Usually, the materials such as NBR nitrile rubber, NR natural rubber, CR neoprene, EPDM rubber, HNBR hydrogenated nitrile rubber, SILICONE, SBR styrene-butadiene rubber, Buna and ACM acrylic ester rubber, their the compression ratio about is 20%. For example, if the hardness is 70 degrees, then O ring, o-rings, o rings and rubber o-rings the compression ratio is 20%. But, the special material such as FKM, VITON, fluorine rubber, FLS fluorine rubber and PU polyurethane, these materials the compression ratio about is 15%.

So, O ring, o-rings, o rings and rubber o-rings the lower the hardness, there will be a greater compression ratio. This type product mainly used small pressure surroundings. Of course, they the higher the hardness, there will be a smaller compression ratio. This type product mainly used higher pressure surroundings. Based on the above characteristics, you will be able to selection of the right and suitable for you to use O ring, o-rings, o rings and rubber o-rings.
