Relevant knowledge of EPDM sealing strip


EPDM sealing strip is formed by microwave one-time vulcanization process. Smooth surface, good elasticity, resistance to compression deformation, weather resistance, ozone resistance, chemical resistance, fire prevention. And a wide operating temperature range and other excellent performance. EPDM is a copolymer of ethylene, propylene and a small amount of a third monomer non-conjugated diene. EPDM rubber has excellent anti-ultraviolet, weather resistance, heat aging, low temperature resistance, ozone resistance, chemical resistance, water resistance and other physical and mechanical properties, good electrical insulation and elasticity. These advantages arePVC and other materials can not be replaced. For products with different shapes, different materials or cold resistance, heat resistance, foaming, physical and special performance requirements, EPDM sealing strips can meet the needs of design and use.


EPDM sealing strip features:

1. EPDM sealing strip has excellent weather resistance. Weather resistance refers to long-term resistance to severe cold, heat, dryness and humidity, excellent resistance to rain and snow erosion, and can completely extend the service life of the rubber strip;

2, heat aging refers to the hot air has a strong anti-aging ability. 100-120 ℃ can be used for a long time, 140-150 ℃ can maintain effective physical properties for a long time. It can withstand high temperatures of 230-260°C in a short time. Can be used for emergencies in urban construction. Coupled with the use of a special formula, EPDM has a similar feel at temperatures from -50°C to 150°C, creating higher performance for production site installation.

3, because the EPDM sealing strip has excellent ozone resistance, it is also called "crack-free rubber". It is especially suitable for urban buildings with different atmospheric indicators and completely exposed to the air. It will show its superiority.

4. Anti-ultraviolet, providing environmental protection for high-rise building residents; withstand voltage 60 ~ 150KV, resistant to corona, electric cracking, and arc. Low-temperature elasticity, the temperature at which the tensile capacity reaches 100MPa is -58.8°C.

5. Due to the excellent physical and mechanical properties of EPDM sealing strips, they are commonly used in the manufacture of aircraft, automobiles, trains, buses, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat insulation window sealing strips and diving products, and high pressure steam Waterproof parts, such as industrial and agricultural seals for hoses, tunnels, viaduct joints, etc.
