PU foam raw material polyol mdi isocyanate for polyurethane Sandwich panel
SPC-1006 series polyol is a fully formulated polyol blend, especially developed for the polyurehane 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 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.
Specifications of pu raw material:
|Cream time (s)||10-35|
|Gel time (s)||50-230|
|Tack free time (s)||60-360|
|Free rise density (kg/m3)||23-38|
Polyurethane is easy to absorb water. Must be strictly sealed to prevent the escape of blowing agent and moisture enter.
Should be placed in a dark, dry, cool and well ventilated place, away from heat and prevent exposure.
The ideal storage temperature is 15-30℃. If the temperature is higher than 30℃, then shelf life cut short
Shelf Life: six months
