The difference is EPDM. It’s what makes roofing material able to withstand years and years of extreme sun, heat, snow, and rain… It’s in windshield wipers, car gaskets, and any number of products that require extraordinary stability in harsh environments… It’s Ethylene Propylene Diene Monomer, also known as EPDM, and it’s what gives AEROFLEX EPDM^™ insulation its extraordinary durability, even in the most demanding environments and applications.

Long-term moisture protection against the elements.
AEROFLEX EPDM^™ delivers proven performance in demanding operating environments – interior and exterior, cold line temperatures, high ambient and relative humidity, and UV exposure.
