Spray Two-Component Polyurethane Foam Insulation PU Foam Introduction
Water-based polyurethane flexible foam is an environmentally friendly foam with water as the blowing agent, which has excellent properties such as low density (8~10kg/m 3 ), open cells, and flame retardant (B3 grade).
During the on-site spraying process, the small openings for breathing are filled with air, and will not produce toxic gases that destroy the ozone layer (traditional foaming agents: F-11, HCFC-141B), and are environmentally friendly and low-carbon new building materials.
This spray PU foam has properties such as heat insulation, gas barrier, moisture-proof heat insulation, waterproof, sound absorption, etc., and can give us a quieter, healthier, and more energy-efficient building.
It is suitable for various thermal insulation projects using spraying technology such as cold storage, tanks, large pipelines, and building walls.
