The Cold storage is a warehouse with proper humidity and low temperature conditions that processing and storing products. To avoid the external heat’s penetration, the storage walls, floors and ceilings are paved with insulation materials which is polyurethane foam currently. After application, the refrigeratory is in long-term low temperature conditions that has much temperature difference with outside environment then will causerefrigeratory’ s deformation. The common polyurethane foam will contract even crack and peel off that will affect the normal application. Besides, the deterioration of common polyurethane foam may decrease the service life of refrigeratory. SWD Co., USA developed cold storage special polyurethane rigid foam which has excellent insulation and dimensional stability, anti-aging. It has been widely applied in the refrigeratory fields in the America and Australia.
Applied with high functionality polyether to get the three-dimensional structure foam network that greatly improved the foam’s low temperature resistance and dimensional stability. High closed-cell rate to make sure the excellent heat insulation and waterproof moisture resistance performance. Firmly bonded with substrate forming a seamless insulation barrier, it is very energy efficient with high performance of impact resistance, anti-extrusion, without crack or embrittlement after long-term application.
