PUR (PIR) polyurethane roofing

The outer layer of the polyurethane sandwich panel is made of high-grade metal plates such as color steel plate, stainless steel plate, aluminum plate, copper plate, etc., and the insulation core material is PUR (PIF) rigid polyurethane insulation foam. Using the roller principle, the imported continuous production line is rolled and foamed once. It is a new type of high-grade building material that integrates heat preservation, heat insulation, load-bearing, and waterproof, with rich colors and beautiful appearance. It has the characteristics of fire retardant, wide temperature range, low thermal conductivity, non-toxic and tasteless, waterproof and moisture-proof, and easy construction. Suitable for steel structure workshops, quick-frozen food processing and refrigeration (aquatic products, poultry, poultry, conditioned food, vegetables, fruits), meat production plants, food processing plants, assembled cold storage, seed storage, biological and pharmaceutical products, milk Product storage, etc.)
