产品 polyurethane insulation boards liquid polyurethane foam for polyurethane sandwich panel machinery
SPC-1006 polyol is a fully formulated polyol blend, especially developed for PU rigid foam insulation, applied with metal face sheet or non-metalic face sheet like Mgo, OSB, etc. It contains sufficient quantity of blowing agent HCFC 141B to achieve the foreseen foam density. When SPC-1006 polyol and isocyanate (MDI) are mixed together using suitable equipment, the good flowability of the resulting foam makes it possible to achieve a homogenous foam density throughout the cross section of the panel. Foams which are allowed to cure for a sufficient time in the mould according to the foam thickness show good adhesion to the surface and good dimensional stability. SPC-1006 polyol contains sufficient amount of fire retardant for the foreseen applications and the foams obtained by using it together with isocyanate (MDI) are classified as B2 or B3 according to DIN 4201 classification. It is recommended that a mould surface temperature of 40℃ is maintained during production.
