EPDM is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diolefin, referred to as EPDM. Solar photovoltaic panel sealing strip has excellent uv resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical medium resistance, water resistance, good electrical insulation and elasticity and other physical and mechanical properties, these advantages are irreplaceable PVC and other materials.

1 epDM sealing rubber strip density is a low rubber, its density is 0.87; In addition, a large number of oil filling and filling agent can be added, which can reduce the cost of rubber products, make up for the shortcomings of the high price of ethylene propylene rubber rubber, and for the high value of epDM rubber strip, high filling physical mechanical energy reduction is not large.

2. Epdm sealing rubber strip has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil filling and normal temperature liquidity. Epdm rubber strip can be used for a long time at 120℃, and can be used temporarily or intermittently at 150-200℃. Adding suitable antiaging agent can raise its service temperature. Epdm crosslinked with peroxide can be used under harsh conditions. Epdm rubber can not crack for more than 150h under the condition of ozone concentration of 50pphm and stretching of 30%.
