Materials for different scenarios
1. Nitrile rubber (NBR): NBR has good oil resistance and abrasion resistance, and is widely used in general industrial applications.
2. Fluoroelastomer (FKM): FKM has excellent resistance to high temperature and chemical corrosion, suitable for high temperature and strong acid and alkali environment.
3. Silicone rubber (VMQ): VMQ has good resistance to high and low temperatures, can provide stable sealing effect under extreme temperature conditions.
4. Ethylene Propylene Rubber (EPDM): EPDM has good aging and ozone resistance, suitable for outdoor environment and some special applications.
5. Polytetrafluoroethylene (PTFE): PTFE has excellent resistance to high temperature and chemical corrosion, used in some special requirements.

MATERIAL | TEMP | ADANTAGES | LIMITATION |
Nitrile Rubbrt (NBR) | -40~125℃ | ■Good oil and fuel resistance■High tensile strength ■Low swelling in water | ■Poor weather and ozine resistance■Poor resistance against polar lkuids ■Poor resistance against clhydrocarbon ■Poor resistance against aromatic fluids |
Fluorinated Rubber (FKM) | -20~250℃ | ■The resistance against oil and fuels is better than other types■The only highly elastic rubber whice is resistance to aromatci and chlornated hydrocarbons ■Exccllcent hcat resistance ■Exccllcent weather and ozonc resistance ■Exccllcent acid resistance ■Low swelling in water | ■Limited cold flexibliity■Limited tensile and tear strength ■Limited wear resistance ■High compression set in hot water ■Poor resistance to polaric solvents |
Polyacrylate Rubber (ACM) | -25~150℃ | ■Good oil and fuels resistance■Good weater and ozone resistance | ■Not usable in contact with water and water solutions ■Limited cold flexibility ■Limited tensile strength and tear resistance ■Poor wear reisistance ■Poor resistance against polar and aromatic and chlorinared hydrocarhons |
Silicone Rubber (VQM) | -60~225℃ | ■Best heat resistance of all rubber types ■Excellent low temp resistance of all rubber types ■Excellent weather and ozone resistance | ■Poor tensile and tear strength ■Poor wear resistance ■Sensitive to hydrolysis ■Poor resistance against aromatic oils and oxidized mineral oils ■Poor diffusion resistance |
What are the advantages of star sealing ring compared with 0-type sealing ring?
1, sealing reciprocating movement, will not turn over, twisting; 2, because the required radial pre-compression is small, so the contact stress is small, friction is also small; 3, sealing reciprocating movement, will not turn over, twisting
2, because the required radial pre-compression is small, so the contact stress is small, friction is also small.
3, between the protruding part in the work of full of lubricant, so the lubricant condition is good friction coefficient is small.
4, working condition contact stress distribution is uniform, so the leakage is small, long life;.
5、Because the parting surface of the seal is located between the two lips, so the fringe will not affect the sealing effect.
