EPDM waterproof membrane is made from ethylene propylene diene monomer (EPDM), adding into some chemical auxiliaries,
for example, carbon black, nanophase modifier, plasticizer, vulcanization accelerator and others,
it is one kind of polymer waterproof membrane with excellent performance elasticity.
