Characteristic performance of EPDM sealing strip

2022-06-29


The function and service life of EPDM sealing strip are usually equivalent to those of vulcanized EPDM rubber sealing strip. The processing energy consumption of EPDM sealing strip is relatively low compared with vulcanized EPDM strip. EPDM sealing strip does not contain heavy metals such as halogen and lead in the production process, so it can be recycled after several years, which can also meet the requirements of green building materials. In addition, its specific gravity is small, generally only0.9-0.95, so the window rate is high. Although the unit price of EPDM sealing strip seems to be very high, its actual application cost is very low.

EPDM sealing strip how? It has good performance characteristics, the following to introduce a few points:

三元乙丙密封条

1. EPDM sealing strip has good weather resistance, which means that it has long-term resistance to severe cold, high temperature, dryness and humidity, and has good corrosion resistance to rain and snow water. EPDM strips can extend the service life.

2. The heat aging resistance of EPDM sealing strip refers to its strong heat resistance to air aging. It can maintain effective physical properties for a long time at 140-150°C, and can be used for a long time at 100-120°C. It can withstand high temperatures of 230-260°C in a short period of time, thereby delaying the occurrence of accidents in urban buildings. In addition, by using a special formula, EPDM rubber has a similar feel in the temperature range of -50°C to 150°C. Thus for the production site installation to improve the efficiency.

3. Due to its good ozone resistance, EPDM sealing strip is also called "crack-free rubber", which is especially suitable for various urban buildings with different atmospheric indexes and completely exposed to the air, which will show the superiority of its products.

4. EPDM sealing strip can withstand 60-150kV voltage, corona resistance, electrical cracking resistance and arc resistance are also very good. When the tensile strength reaches 100MPa, the temperature is -58.8 ℃.

5, becauseEPDM sealing stripGoodPhysical and mechanical properties, it is usually used to manufacture high and low voltage switch cabinets, buses, airplanes, automobiles, trains, ships, diving products, high pressure steam hoses , Tunnels, glass curtain walls, aluminum alloy heat insulation windows, viaduct joints and other waterproof parts, and other industrial and agricultural sealing parts.
