1, three ethylene propylene has excellent weather resistance, weather resistance refers to a long-term cold, hot, dry, wet ability, corrosion resistance to rain and snow water, can prolong the service life of the rubber strip; 2, heat aging refers to a strong heat resistant air aging. Can be used at 100-120℃ for a long time, at 140-150℃ can also maintain effective physical properties for a long time, a short time can be resistant to 230-260℃ high temperature, the city building sudden accident, can play a role; Combined with the use of a special formula, EPDM rubber at -50℃ to 150℃ feel similar, which created a job performance for the production site installation 3. Due to the ozone resistance of EPDM, it is also known as "non-crack rubber". It is especially used in various urban buildings with different atmospheric indexes and completely exposed to the air, which will show the superiority of its products. 4, anti-ultraviolet radiation, for high-rise building residents to provide environmental protection; Can withstand 60~150KV voltage, corona resistance, electric cracking resistance, arc resistance, also very good. Low temperature elasticity, tensile capacity of 100MPa when the temperature is -58.8℃. 5, due to the excellent physical and mechanical properties, thus has often been used in the manufacture of aircraft, cars, trains, buses, ships, high and low voltage switchgear, glass curtain wall, aluminium alloy window heat sealing parts and diving products, high pressure steam hose, tunnels, the viaduct connectors waterproof parts and other industrial and agricultural seal parts.
