PU sandwich panel
The polyurethane cold room panel is composed of two galvanized steel sheets and rigid polyurethane foam in the middle. Because the polyurethane cold room panel has several outstanding advantages, such as thermal insulation, waterproof, light weight and fast installation, It has been widely used as the building material of cold storages, cool rooms, clean rooms, free-dust workshops and exterior walls in cold places.

PIR/PUR Sandwich panel
PIR Polyisocyanurate is called PIR for short. For the composite boards developed, excessive isocyanurate is added and ring structure and higher isocyanurate index are employed in the compounds to form compact PIR products, thus ensuring greater stability and excellent heat and fire resistance for the internal rigid foams. Experiments show that the products can endure a temperature up to 200℃ in short time period or to 160℃ for long time. PUR In terms of raw material proportioning and process output, PUR products employ the globally advanced six component online automatic (SIMENS) mixing and pouring technology and have realized six-component continuous foaming for the first time in China. With the technology, mixing and proportioning process may be finished in an online way;the formula may be adjusted according to environmental changes; air feeding and mixing devices may be used to make raw material mixing more even and foam finer, thus producing high-strength, energy-saving and environment friendly building boards.cold storage (PIR/PUR) sandwich panel
