Kingflex NBR is a flexible closed cell elastomeric thermal insulation foam

Kingflex NBR is a flexible closed cell elastomeric thermal insulation foam, with high water vapor diffusion resistance factor and low thermal conductivity, designed for both indoor and outdoor use; however, external use requires additional protection from weather and UV radiation.

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).

Description

Kingflex flexible elastomeric closed-cell foam pipe insulation, also known as rubber, is composed of synthetic rubber. The two main foam rubber formulations that are commercially available are nitrile butadiene rubber with PVC (NBR/PVC). The insulation materials are widely in multiple scenes for thermal insulation and noise reduction, which are used in various pipes and equipment, such as central air conditioning, air conditioning units, construction, chemical, medicine, electrical appliances, aerospace, auto industry, thermal power etc.
