Closed -cell electronic nitrile rubber insulation is no moisture absorption,antierosion and extremely tough. It is mainly applicable to central airconditioner system, building, ship, automobile,etc. Because of its softness and toughness, it can be used in heat insulating and fireproof of parts with irregular shape, such as valve,elbow,tee joint,etc.
