Flexible Foam Rubber Insulation Pipe 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. NBR 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 pipe. 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).
