Hinude FKM FKM Rubber Oil Seals High Temperature Resistant For Auto Engines
High Temperature Resistant FKM FKM Rubber Oil Seal for Auto Engines
Introduction of the Materials for Auto Rubber Oil Seals
There are many substances of oil seals. All of which range in resilience to unique conditions.
The maximum typically used substances in oil seals are Buna (Nitrile) and FKM®.
Buna (Nitrile) oil seals are the maximum broadly used elastomer in sealing.
Nitrile oil seals have exceptional resistance to petroleum oils and fuels, mineral oils and greases, hydraulic fluids, water, steam, and alcohol. Nitrile has a exceptional set of attributes along with low compression set, excessive tensile strength, and abrasion resistance.
Usage of the Rubber Oil Seals:
Oil seals are used to shield shafts and bearings from ingress of dust and overseas count and egress of oil or grease. An oil seal typically includes an outer round steel element and an internal bendy member that does the real sealing and is bonded to the steel element through chemical adhesive agents. The sealing member is manufactured from rubber, both artificial or herbal because the case might also additionally be. The sealing lip of the bendy member is ready through slicing away the flash that paperwork on the sealing aspect throughout molding. A great sealing aspect affords good enough strain at the shaft to save you leakage.
Feature of some Rubber materials:
| Material | Temperature( ℃ ) | Advantage |
| NBR | -40~+125 | Excellent abrasion resistance, Mineral oil resistant. |
| SIR | -60~+225 | Excellent heat resistance, cold resistance and weatherability. |
| FKM | -20~+250 | Have good heat resistance, oil resistant and chemicals resistance. |
| EPDM | -40~+125 | Water resistance, resistance to polarity, solvent resistance, inorganic drug resistance, and good weatherability. |
| SBR | -50~+100 | Resistance to polarity, solvent resistance, Excellent resistance to water |
| PTFE | -45~+100 | Heat resistance, Excellent cold resistance, chemicals resistance, goodweatherability, Low friction coefficient of oil seal materials |
