Epdm sealing strip 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 functions. These advantages are PVC and other materials can not be replaced.
Epmc sealing strip is molded by microwave vulcanization process, the surface is smooth and beautiful, with good elasticity and resistance to compression deformation, weather aging resistance, ozone resistance, chemical resistance and wide application temperature scale (-50℃ ~ 150℃) and other functions, has been widely used in automobile doors and Windows curtain wall manufacturing operations. For different shapes, different raw materials, or cold resistance, heat resistance, foaming, solid body, as well as with special functions and other requirements of the commodity, can be satisfied with the planning and application of the demand.
Epdm sealing strip characteristics:
1, epDM sealing strip has excellent weather resistance, weather resistance refers to a long time resistance to cold, hot, dry, wet ability, has excellent corrosion resistance to rain and snow water, completely can extend the service life of rubber strip;
2. Heat resistance aging refers to a strong heat resistance to air aging. Can be used in 100-120℃ for a long time, in 140-150℃ can also adhere to the useful physical properties in the appropriate period of time, short time can withstand the high temperature of 230-260℃, when the urban construction accident, can play a delay effect; Combined with the use of special formula, EPDM rubber feel near -50℃ to 150℃, which for the production of field device invention of high efficiency performance;
3, because epDM has outstanding ozone resistance, also known as "crack free rubber", especially used in different atmospheric index, completely exposed to the air in all kinds of urban buildings, more will show the superiority of its goods; ?
4, anti-ultraviolet radiation, for high-rise building residents to provide environmental protection effect; Can withstand 60 ~ 150KV voltage, corona resistance, electric cracking resistance, arc resistance, is also very good. Low temperature elasticity, stretching to 100MPa temperature is -58. 8 ℃.
5, because have excellent physical and mechanical function, and thus is often used to make planes, cars, trains, buses, ships, high and low voltage switchgear, glass curtain wall, aluminum alloy hot broken window scuba diving in the sealing parts and finished products, and high pressure steam hose, tunnels, the viaduct sealing top waterproof parts and other industrial and agricultural parts.
