Rigid PU Foam Insulation for Refrigerator and Freezer

Send Message Request a Quote

The rigid PU foam insulation which is widely applied to refrigerators and freezers, is comprised of system polyol and isocyanate. The formula of system polyol covers polyether polyol, silicone surfactant, catalyst, and additives. Such three foaming systems as HCFC-141B, cyclopentane, and HFC-245fa based type, are for selection.

Properties
This rigid PU foam system comes with the characteristics including short stripping time as well as excellent stability, operability, and mobility. After added with foaming agent, the system polyol will react with isocyanate to form PU foam insulation material characterized by uniform density, high strength, and excellent dimensional stability. This insulation material has strong viscosity. Its performances reach the international advanced level.

In addition, the cyclopentane or HFC-245fa based PU foam insulation is defined as the environmental materials, since it has no damage to the ozone sphere.
