Several standards applicable to epDM door and window curtain wall adhesive strips: one is GB/T 24498-2009(GB) building door and window sealing strips standard; Second, main technical indexes of DIN7863(German standard) building seals; The third is the main technical index of ASTM 864-05(American Standard) building seal strip.

Epdm rubber has excellent low temperature performance, ozone resistance, uv resistance, weather resistance and aging resistance. Good electrical insulation, chemical resistance, impact elasticity, acid and alkali resistance, small specific gravity, heat resistance up to 150℃, polar solvent - ketone, ester, etc., with excellent physical and mechanical properties and low compression permanent deformation; It is mainly used in automobile, curtain wall, shield rubber sealing strip, chemical equipment lining, wire and cable wrapping, steam hose, heat-resistant transport belt and other industrial products.

1. Excellent low temperature performance: Most vulcanized products are relatively soft at -50℃, that is, they have good elasticity and low compression permanent deformation at low temperature, so that they will not reduce their sealing performance due to low ambient temperature in cold regions, and it is easier for construction in winter in cold regions.

2. High filling capacity: EPDM rubber has a much higher filling capacity than any other rubber, which reduces the cost without reducing the performance.

3. Low density: EPDM rubber is almost the lightest of all synthetic rubber, so its finished product has a relatively light specific gravity, which also determines its wide application prospect.

4. Excellent resistance to ozone, ULTRAVIOLET, weather and aging, ranking first in general rubber. Good electrical insulation, chemical resistance, impact elasticity, acid and alkali resistance, small specific gravity, heat resistance up to 150℃, polar solvent - ketone, ester, etc., with excellent physical and mechanical properties and low compression permanent deformation.
