Product Description

The heat-retaining material of sandwich layer uses PUR/PIR hear-preservation polyurethane foam. Take use of the roller principle, the plate is roll-in foaming that formed by imported continuous  production line. Polyurethane sandwich panel is a kind of high grade new mode building materials with various color and attractive appearance that combined temperature preservation, heat insulation, weight sustaining, water proof and such kind of good properties together. Moreover, they have the favorable performance of burning resistance, suitable temperature range extensity, thermal conductivity coefficient lowness, no-poison &no-odor, water-proof&moisture-protection,simple and convenient installation. Therefore, they are widely used as roof and wall of various buidings,such as large scale industrial plant, electrical power plant, airport and exhibition halls.
