A brief understanding of the EPDM sealing strip


EPDM sealing strip is formed by microwave primary vulcanization process. Smooth surface, good elasticity and resistance to compression deformation, weathering resistance, ozone resistance, chemical resistance, fire resistance. 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 UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity and other physical and mechanical properties. These advantages arePVC and other materials can not be replaced. For products with different shapes, different materials or cold resistance, heat resistance, foaming, entity, and special performance requirements, EPDM sealing strips can meet the needs of design and use.

EPDM sealing strip characteristics:


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

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

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

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

5. Because EPDM sealing strip has excellent physical and mechanical properties, it is often used in the manufacture of airplanes, automobiles, trains, buses, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat insulation window seals and diving products, high pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural seals.
