Block System

ISP BF 40-2  series blended polyols are a block rigid foam system designed with n-Pentane and HFC – 365mfc/227ea as blowing agent. They are widely used to produce polyurethane foam boards for different applications, such as cold storage, refrigeration trucks, climate-controlled rooms, warehouse, etc. 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 B3 grade (O.I.<23%) according to DIN 4102, good density distribution, high compressive strength and excellent dimensio- nal stability.The thickness of the foamed polyurethane core can range from 50mm to 200mm depending upon required insulation characte- ristics.
