Rigid PU Foam Insulation for Water Heater

Send Message Request a Quote

The rigid PU foam insulation is chiefly used to water heater. It includes system polyol and isocyanate. System polyol is made of polyether polyol, blowing agent, silicone surfactant, catalyst, and additives. Such three foaming systems as HCFC-141B, cyclopentane, and all-water-blown based type, are for your choice.
