Three EPR seal, namely, three ethylene propylene (EPDM) adhesive strip, is formed by microwave vulcanization. It has good surface and beautiful appearance. It has good elasticity and anti compression deformation. It is resistant to weather aging, ozone resistance, chemical resistance, fire resistance and wide use temperature range (-50 C ~+150 C).
Summary:
Three ethylene propylene rubber (EPDM) is a copolymer of ethylene, propylene and a small amount of third monomeric non conjugated dienes. The international name is Ethyiene Propyene Diene Methyiene (EPDM).
Three ethylene propylene rubber has excellent anti ultraviolet effect, with weatherability, heat-resistant aging, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity, and other physical and mechanical properties. These advantages are irreplaceable for PVC and other materials.
Three ethylene propylene (EPDM) adhesive strip is formed by microwave vulcanization process. It has good surface and beautiful appearance, good elasticity and anti compression deformation. It has excellent properties such as weather aging, ozone resistance, chemical resistance and wide use temperature range (-50 C ~+150 C). It has been widely used in the manufacturing industry of car door and window curtain wall. It can meet the needs of design and use for different shapes, different materials, or cold, heat resistant, foaming, real body, and special properties.


Characteristic:
1, three ethylene propylene has excellent weather resistance, weather resistance refers to the long-term resistance to cold, hot, dry, wet ability, the erosion of rain and snow has excellent corrosion resistance, can completely prolong the life of the adhesive strip.
2, heat aging refers to strong heat resistance of air aging. It can be used at 100-120 C for a long time. It can maintain effective physical property at 140-150 C for quite a long period. It can endure a high temperature of 230-260 C in a short time. It can play a delayed effect on urban building accident. With the special formula, the handle of ethylene propylene rubber (three) is similar at -50 C to 150 C, which is produced now. Field installation creates efficient work performance
3, since EPR has excellent ozone resistance, it is also known as "crackless rubber". It is especially used in various urban buildings with different atmospheric index and completely exposed to air. It will show the superiority of its products.
4, anti ultraviolet radiation for high-rise building residents to provide protection of the environment; can withstand 60~150KV voltage, corona resistance, resistance to electric cracking, arc resistance, is also very good. Low temperature elasticity, the tensile capacity reaches 100MPa when the temperature is -58.8 C.
5. Because of its excellent physical and mechanical properties, it is often used in the manufacture of aircraft, cars, trains, buses, ships, high and low voltage switchgear, glass curtain wall, sealing parts of aluminum alloy heat breaking windows, submersible products, high pressure steam hose, tunnel, viaduct joint and other water-proof parts, and other industrial and agricultural seals .
