Description

AK-Flex rubber insulation foam is a kind of black flexible elastomeric nitrile rubber foam. It is original closed cell and fiber-free elastomeric foam. It is furnished with a smooth skin on one side which forms the outer exposed insulation surface. The expanded closed-cell structure makes it an efficient insulation. It is also effective for reducing HVAC noise.

This rubber foam insulation sheet is 100% foaming and completely closed cell inner structure, fiber-free elastomeric thermal insulation material, and it is highly recommended for condensation control due to its excellent moisture vapor resistence and thermal conductivity, which is mainly used for pipe, duct and container. It is manufactured without the use of CFC’s, HFC’s or HCFC’s, which makes it as a kind of environmental-friendly material. As a kind of high quality thermal insulation and energy saving material, it is widely applied for HVAC/R system’s duct, water-pipe, refrigeration and heating equipment, process piping and hot water pipe insulation works.
