Rubber and plastic

Plastic and rubber insulation board is soft heat-insulating, heat-preservation and energy conservation materials made from advanced technology and advanced full-automatic continuous production line, with nitrile-butadiene rubber and polyvinyl chloride (NBR, PVC) which perform best as main raw materials and other high quality auxiliary materials through foaming and special procedure.

Application:

Central air conditioning system refrigeration units and equipment

Frozen water pipes

Condensate pipe

Ducts and hot water pipes
