Polytetrafluoroethylene |
PTFE | Good chemical stability, high mechanical strength. Anti heat, cold, water, oil, pharmaceuticals, and other Mediums. Pressure 40MPa.Good wear resistance, low friction, self-lubrication. | -190～260 | Main material for wear rings, guide rings, back up rings,, and widely used in metallurgy, petrochemical, engineering machinery, light industrial machinery |
| Nitrile Rubber | NBR | Anti oil, and heat. Good wear resistance. Widely used in the production of seal products, but not for phosphonate Series hydraulic oils and gear oils containing polar additives. | -40～120 | For the production of O-rings, oil seals, seal cups, and etc., suitable for general hydraulic and pneumatic systems as static seal or dynamic seal. |
| Rubber and Plastics | RP | High elasticity, and high strength. Other characteristic are as same as NBR. | -30～100 | Material of O-rings,Y type rings, and wiper seals (dust rings). Mainly used in construction machinery and all kinds of high-pressure hydraulic systems. |
| Nitrile Rubber + Cloth | NBR+Cloth | Complex by the NBR and cloth, high strength, wear resistance decreased slightly over NBR, other characteristic are as same as NBR. | -30～100 | Making cotton fabric seals for sealing construction machinery, metallurgical equipment, and various high-pressure systems. |
| Viton | FKM | Anti heat, acid, chemicals, and oil (including phosphonate series of hydraulic oil), applies to all oil, gasoline, hydraulic oils, synthetic oils | -20～200 | Suitable for high temperature, chemical resistance, flame hydraulic oil seals. Widely used in metallurgy, electric power and other industries. |
| Polyoxymethylene Delrin | POM | Oil, temperature, wear resistance, high compressive strength, good impact resistance, has good self-lubricating properties, good dimensional stability. | -40～120 | For the manufacture of the guide rings, back up rings. |
| Phenolic Cloth | FQ | Oil, temperature, wear resistance, high compressive strength is 2-3 times than the thermoplastic material, better impact resistance, good dimensional stability | -50～130 | For the manufacture of the guide rings, the guide bushings. |
| Polyurethane | TPU | Good mechanical properties, excellent wear resistance, excellent oil resistance. | -35～100 | For the manufacture of the high-pressure hydraulic seals. |
