Polyisocyanurate foam, abbreviated as PIR, is produced using Winsheng's independently developed combined polyether and methylene diphenyl diisocyanate (MDI) as core raw materials. Adhering to environmental protection concepts, it contains no ozone-depleting substances such as CFC/HCFC, with an ODP (Ozone Depletion Potential) of 0. It features excellent mechanical strength and superior thermal insulation performance, maintaining stable and reliable performance under cryogenic and ultra-low temperature working conditions. It can be prefabricated into boards or pipe shells, or applied via on-site pouring and foaming.
