Product Description

Polyurethane PU Expanding Foam Pipe Insulation Raw Material

     SPC-1013 series polyol is a fully formulated polyol blend developed for piping insulation. Has the effect of noise insulation, thermal insulation, etc. Liquid flow smoothly, uniform density, good cell structure. Has excellent dimensional stability and good insulation properties at low temperatures.


    The component ratio has been adjusted to make it suitable for use with polyurethane foam spraying machines with a fixed volumetric component ration of 1-1.2:1. It already contains sufficient quantity of blowing agent HCFC 141b to achieve the foreseen foam density.


    When polyol and isocyanate (MDI) are mixed together using suitable foam spray equipment, the resulting foam has a homogenous density. Foams which are allowed to cure for a sufficient time between the layers applied have good skin formation and show good adhesion to the sprayed surface. Special care must be taken the sprayed surfaces are not cold or wet.

 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

Package: Polyol (A):220kg/iron drum

         Isocyanate (B): 250kg/iron drum
