Rubber Insulation Material

Rubber Insulation Material: pvc nbr plastic rubber foam material, armaflex substitute, used for thermal insulation

Rubber Insulation Material:

Production:

The pvc/nbr rubber foam sheet is made from the nitrile -butadiene rubber (NBR) and polyvinyl chloride(PVC) as main raw material and other high quality auxiliary materials through foaming.

Features:aperture-closing elastic material, good thermal conducivity at 0.034 w/m.k,non-flammable,good chock absorption and sound-absorption,no pollution for the envorinment.

Applications:

widely used in cold/hot medium piping and containers in central control air condition, construction, chemical industry,medicine, light industry, textile process, metallury, boat, vehicle,electrical apparatus and other fields.

Size: grade B1 and B2,thickness from 3mm to 30mm,width 1200mm or 1000mm,length can be customer-made,
