EPDM rubber gaskets can resist Abrasion, UV rays, Ozone, aging and Weather. EPDM is also steam resistant, and its resilient & flexibility has law Electrical conductivity, and adheres easily to Metals. EPDM insulates and reduces noise , part of the reason it’s so commonly used in the automotive and Industrial applications. It is also used for sealants, expansion joints, garage door seals, pool and tank liners. It’s even used on RV roofs.
