ISP CP 236 series blended polyols are continuous PUR sandwich panels system designed for 2 Component Machine with n-Pentane as blowing agent. They are widely used in the insulation layer of workshop, prefabricated houses and common building. Excellent operationally, flowability, adhesive strength and good demolding are the main features when they react with PMDI (normal functionality) which is the recommended isocyanate for the formulation. The manufactured foam has a fire behaviour B2 grade according to DIN 4102, good density distribution, high compressive strength and excellent dimensional stability. The thickness of the foamed polyurethane core can range from 100 mm to 200 mm depending upon required insulation characteristics.
