EPDM Gasket

EPDM Rubber Gasket, also known as EPDM Gasket, EPDM Seal and EPDM Washers, is made of EPDM compound material(commonly black color), which has superior resistance to Ozone,water and steam making it the best choice for long term UV exposure and outdoor sealing applications.
  • EPDM

EPDM  Gasket, also known as EPDM Rubber Gasket, EPDM Seal and EPDM Washers, is made of EPDM compound material(commonly black color), which has superior resistance to heat,ozone and aging and electrical insulation making it the best choice for auto parts, wire &cable, waterproof rolling materials, outdoor sealing applications and other fields.

EPDM Rubber Seal is the largest consumption in automotive rubber,mainly manufacturing door and window sealing tape, radiator rubber hose and other parts.

EPDM Rubber Gasket is usually manufactured by compression molding, rubber injection molding and die cut tool.

EPDM Gasket Properties and Application

EPDM Gasket has excellent ozone-resistant, heat-resistant, weather-resistant, which can be in long-term operation under 150℃, generally EPDM sealing gasket is working -55~150℃. So EPDM seals usually are used for  heat-resistant rubber hose, transport belt, radiator hose and spark plug sheath etc.

EPDM Sealing Gasket has good uperheated water resistance,electrical property,elasticity and adhesion.So EPDM gasket is a deal thermal insulation materials for automobile, marine, household appliances, electronic equipment, medical devices, fitness devices and air-condition pipe, etc.

EPDM Rubber Gasket has the lowest density in all rubbers, which is able to absorb a lot of fillings & oils while has little effect on EPDM properties. Therefore, EPDM rubber seal usually is made into low-cost rubber compounds.

EPDM Rubber seal has good resistance to water and chemicals, which can be used for alcohols & ketones ,sealing under high temperature steam, bathroom equipment, auto radiator & braking systems. However, EPDM washer is not recommended for food application pr exposure to mineral oil.

EPDM Washer has excellent electrical insulation and corona resistance, which volume resistivity can reach 106O.m, and breakdown voltage is about 30-40MV/m, the dielectric constant is also low. Especially its electrical properties change is also small after immersion. So EPDM rubber gasket is mainly used for wire & cable sleeve, household Electrical accessories etc.

EPDM Gasket Disadvantage

EPDM rubber Gasket has slow curing rate.

EPDM Seal has inferior in resistance to oil , fuel and aliphatic- solvent.

EPDM sealing Gasket is difficult to blend with other unsaturated rubbers.

EPDM rubber seal has poor self-adhesion and mutual viscosity.

EPDM Gasket has poor bonding property with other materials results in poor proccessing performance.

EPDM Gasket compare with Other Rubber Gasket

Compare to Silicone gasket and FKM gasket, the physical mechanical properties and comprehensive performance of EPDM Gasket are more balanced, and also EPDM gasket has a better development advantage of raw material and low proccessing cost. However, the vulcanization speed of EPDM rubber Gasket is slower, and also the cohesiveness and resistance to aliphatic solvents are inferior.

Compare to NR gasket witexcellent elasticity  and ideal physical mechanical properties, the resistance to ozone and weather of EPDM gasket is superior. If NR and EPDM can be used well together, the advantages and disadvantages will be complementedm, but the problem of co-curing is the key to the success or failure of these two rubber blends.

Compare to NBR gasket has a good  resistance to oil, together with the typical polar rubber NBR, EPDM provides a new material that is resistant to high temperatures, oils, ozone and aging.

Compare to CR gasketEPDM rubber gasket has a good resistance to low temperature and oxgenated-solvent, but poor resistance to rebound , gas impermeability and alcohol.
