The raw materials of Daewon rubber rings are E.P.D.M(Ethylene Propylene Diene Monomer) which is a kind of rubber composed of non-nodal high molecular substance of hybrid polymerized ethylene and propylene.
E.P.D.M is a medium property between natural rubber and SBR and having good heat resistance, ozone resistance, and chemical resistance is also used in the automobile parts, oil seal, hose, low density polyethylene and etc.
Daewon rubber ring is a perfect product in terms of the insertion and water tightness.
