How about EPDM sealing strip? It has good characteristics. Hebei Baoyu seal manufacturer will analyze it for you:

1. EPDM sealing strip has good weather resistance, which means that it has the ability to resist cold, high temperature, dry and wet for a long time. And it has good corrosion resistance to the erosion of rain and snow, and the EPDM adhesive strip can prolong its 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 ℃, and can be used for a long time at 100-120 ℃. It can withstand a high temperature of 230-260 ℃ in a short time, thus delaying the occurrence of accidents in urban buildings. In addition, through the use of special formula, EPDM rubber has a sense of similarity at the temperature of -50 ℃ to 150 ℃, thus creating high efficiency for production site installation.

3. Due to its excellent ozone resistance, EPDM sealing strip is also known as "crack free rubber", which is especially suitable for different atmospheric indexes. All kinds of urban buildings that are completely exposed to the air will show the superiority of their products.

4. It can withstand 60-150kv voltage, and has excellent corona resistance, electric crack resistance and arc resistance. When the tensile strength reaches 100MPa, the temperature is -58.8 ℃.

5. Because of its excellent physical and mechanical properties, it is often used to manufacture buses, aircraft, automobiles, trains, ships, high and low voltage switchgear, glass curtain walls, aluminum alloy heat insulation windows, diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts, as well as other industrial and agricultural sealing parts.
