Plant 5-6, Zhongnan High Tech Industrial Park, Zhegao, Chaohu City, Anhui. 
This product is a closed-cell elastic material, has perfect performances such as soft, anti-bending, cold-resistant, shake-resisting, fire-blocking, water- proof, low thermal conductivity and sound-absorption. It can be widely used for all kinds of cold or hot medium piping lines to reduce cold or thermal loss.
– Has a closed cell structure
– Low thermal conductivity
– Easy installation, high durability
– Good fire and smoke resistance
