Rubber insulation material is made from nitrile-butadiene (NBR) as the main raw materials. NBR Insulation tube & Sheets are closed cell structures minimizing Heat gain or loss with the surroundings. It is widely used in Refrigeration, HVAC and Plumbing. The moisture-resistant characteristics make it especially valuable on chilled-water and refrigeration piping where condensation might otherwise soak through fibrous types of insulation, significantly degrading their thermal performance, leaving them susceptible to fungal growth and ultimately shortening their life cycle.
