EPDM Rubber Flat Washer:
- Working Temperature Range: EPDM can typically withstand temperatures ranging from -40°C to 130°C (-40°F to 266°F). It is suitable for applications that do not involve high temperatures.
- Weather Resistance: EPDM offers excellent resistance to weathering, ozone, and UV radiation. It can withstand exposure to sunlight and harsh environmental conditions without deteriorating.
- Water Resistance: EPDM has excellent resistance to water and moisture. It does not absorb water, swell, or degrade when exposed to moisture, making it suitable for applications that require water resistance.
- Chemical Resistance: EPDM has good resistance to acids, alkalis, and polar substances. However, it may not be as resistant to oils, fuels, and other hydrocarbon-based chemicals.
FPM/Viton Rubber Flat Washer:
- Working Temperature Range: FPM/Viton can typically withstand temperatures ranging from -20°C to 200°C (-4°F to 392°F). It is suitable for applications that involve high temperatures.
- Chemical Resistance: FPM/Viton has excellent resistance to a wide range of chemicals, including oils, fuels, acids, alkalis, solvents, and polar substances. It is highly resistant to degradation and swelling when in contact with many chemicals.
- Weather Resistance: FPM/Viton is generally resistant to weathering, ozone, and UV radiation. However, it may not offer the same level of weather resistance as EPDM.
- Water Resistance: FPM/Viton has good resistance to water and moisture. It is suitable for applications that require water resistance, but EPDM may be a better choice for prolonged exposure to water.
Polyacrylate (ACM): Our ACM offer superior resistance to mineral oil, oxygen, and ozone. While they may not be the best choice for water applications, their resilience in other environments is unmatched.
Polychloroprene Rubber (CR): Known for its versatility, our Neoprene provide excellent resistance to ozone, aging, and chemicals. They maintain robust mechanical properties across a broad temperature spectrum.
Nitrile-Butadiene (NBR): Our NBR material are designed for environments with gasoline and aromatic solvents. With varying acrylonitrile content, they balance swell resistance and flexibility for optimal performance.
Hydrogenated NBR (HNBR): Engineered for superior air resistance, our HNBR material feature a hydrogenated process that enhances thermal stability and oxidation resistance.
Ethylene Propylene Rubber (EPDM): EPDM Washer are a terpolymer blend, offering excellent cross-linking capabilities for a wide range of applications.
Silicone Rubber (VMQ): Our silicone gasket are known for their insulating properties and physiological neutrality, making them ideal for sensitive environments.
