Quick Overview

ER22 Plain NBR/PVC Sponge Sheet

Flexible closed cell elastomeric thermal insulation material for condensation control in air-conditioning, refrigeration and chilled water installations. It is also suitable for reducing thermal losses in heating and plumbing systems. The combination of its technical properties, a low thermal conducting and a high resistance to water vapor transmission and competitive price makes it a cost effective energy saving solution.

Fully Recyclable as the material is CFC and HCFC free.
