It means long-term resistance to severe cold, heat, dryness and humidity. It has excellent corrosion resistance to rain and snow water erosion and can completely extend the use of rubber strips. life; 2. Heat aging resistance means that it has strong heat aging resistance. It can be used at 100-120 °C for a long time. It can maintain effective physical properties for a long period of time at 140-150 °C. It can withstand high temperatures of 230-260 °C in a short time. To the time delay; plus the use of special formula, EPDM rubber is similar in the sense of -50 ° C to 150 ° C, which creates high efficiency performance for production site installation. 3. Because EPDM has excellent ozone resistance, it is also known as “crack-free rubber”. It is especially used in various urban buildings with different atmospheric indexes and completely exposed to the air. It will also show its products superiority. 4. Anti-ultraviolet radiation, to provide high-rise building residents to protect the environment; can withstand 60 ~ 150KV voltage, corona resistance, electric crack resistance, arc resistance, it is also very good and has low temperature elasticity, the temperature at which the tensile capacity reaches 100 MPa is -58.8 °C. 5. Due to its excellent physical and mechanical properties, it is often used in the manufacture of aircraft, cars, trains, passenger cars, ships, high and low voltage switchgear, glass curtain wall, aluminum alloy heat insulation window sealing parts and diving products, high pressure steam hose waterproof parts such as tunnels, viaduct joints and other industrial and agricultural sealing parts.
