What are the characteristics of the train epDM seal?

Characteristics of train epDM sealing strip

1, epDM sealing strip has high quality weather resistance, weather resistance refers to a long time of cold, hot, dry, wet ability. Excellent corrosion resistance to rain, snow and water, which can extend the service life of the rubber strip.

2, heat aging refers to a strong heat aging air, can be used for a long time in 100-120℃, in 140-150℃ can also adhere to the useful physical properties in the appropriate long period, short time can withstand 230-260℃ high temperature, when the urban construction accident, can play a delay effect. Combined with the use of special formulations, EPDM in the range of -50℃ to 150℃ provides efficient performance for production of field units.

3, because epdm has excellent ozone resistance, it is also known as "crack free rubber". Especially used in different atmospheric index, completely exposed to the air of all kinds of urban buildings, will show the superiority of its commodities.

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 has good physical and mechanical function, and thus is often used to make planes, cars, trains, buses, ships, high and low voltage switchgear, aluminum alloy hot broken window scuba diving in the sealing parts and finished products, glass curtain wall, tunnel, the viaduct's waterproof parts and other industrial hose, high pressure steam, agricultural sealing parts, etc.
