China NBR PVC pipe insulation is a flexible elastomeric thermal insulation Manufacturers, Factories

NBR/PVC pipe insulation is a flexible, elastomeric thermal insulation with smooth skin on the outer surface. The expanded closed-cell structure of the synthetic nitrile rubber makes it an efficient thermal insulator for hot water and air conditioning pipes. Normal wall thicknesses of 1/4”, 3/8″, 1/2″, 3/4″,1″, 1-1/4”, 1-1/2″ and 2” (6, 9, 13, 19, 25 , 32, 40 and 50mm). Standard Length with 6ft (1.83m) or 6.2ft(2m).

Flexible Foam Rubber Insulation Pipe Detail
Product Description

Flexible Foam Rubber Insulation Pipe is a black, flexible elastomeric foam tube used to conserve energy and prevent condensation on piping applications. The tube closed cell properties create exceptional thermal and acoustic insulation. It is designed for the insulation of large surfaces, ideal for the insulation of pipes of large diameters. By reducing the number of sections required they simplify installation, saving on time and labor costs. Facing: Pipe can be covered with aluminum foil and adhesive paper.
