external wall insulation waterproof foam material

Product Description

SWD250 Spray Rigid Polyurethane Foam was developed by SWD Urethane Co. USA in the 1970s. It has been widely applied for external wall insulation material in the US and be certified as Energy Star by the USEPA. SWD250 polyurethane foam is a dense structural microporous foam material with low absorption rate, good permeability resistance, above 95% of closed cell content. Applied with direct spray technology, no seams among foam layers that a complete impermeable layer is formed on the substrate. It creates a protection layer avoiding water absorption and perfectly resolves the building walls water-leaking problems and heat insulation issues. 

 

 

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.
