Our thermal insulation pipe/tube uses NBR (nitrile-butadiene rubber) as the main raw material for foaming, resulting in a fully closed-cell flexible rubber insulation material. It is manufactured without any fibrous materials such as HCHO and CFCs, which are harmful to the ozone layer. This product is suitable for the thermal insulation of various pipes and equipment operating within the temperature range of -50℃ to 110℃.
