High-Quality Spray Foam Products – SWD250 Spray Rigid Polyurethane Foam Building walls heat insulation material – SWD
High-Quality Spray Foam Products – SWD250 Spray Rigid Polyurethane Foam Building walls heat insulation material – SWD Detail:
Characteristics
SWD250 external wall rigid polyurethane foam is a new energy efficient insulation material which is instant sprayed-forming by A & B liquid under high pressure of spray gun. The liquid material has good fluidity and permeability under high pressure that be able to keep foaming inside the wall and firmly bond with the base to seal gaps. The adhesive strength(≥40Kpa) bonded with the base surpasses the tear strength of the rigid foam self, it will not peel off even the substrate occurs expansion and contraction. This product is acid and alkali resistant, solvent resistant and anti-aging, the service life is over 50 years which is fit for the service cycle of the building exterior walls and resolved all the problems of traditional materials’ frequent maintenance from water absorption, moisture absorption and leaking. SWD250 is environment-friendly safe applied with newly Eco friendly foaming agent that is solvent free, no volatile and no pollution in production and application process.
