Wide Application of Glass Wool Felt

The foam rubber pipe is a soft heat-insulation energy-saving material made from high-performance nitrile butadiene rubber and polyvinyl chloride as well as multiple high-quality auxiliary materials by special processes. This closed-cell elastic material have many excellent properties, such as flex resistance, heat resistance, coldness resistance, flame retardancy, waterproofness, low heat conductivity, shock absorption, sound absorption, etc. It also has beautiful appearance, produces no pollution, and is convenient to mount.
