Our rubber plastic foaming thermal insulation materials are produced by the cutting-edge technology introduced from abroad and the automatic production h nitrile rubber and polyvinyl chloride in exnt performances as the man materials and after processes of banburying, sulfuration foaming, etc. It’s main characteristics are as follows: With closed foam structure and low density, the products are in low thermal conductivity, water vapor permeability and water absorption and good flexibility, and they are easy to be used in construction. The products allow a wide temperature range for application from -40? to 105?, with good age resistance and fire resistance.
