H467 Blended polyol (low initial K factor)
Refrigerators and freezers
H467 is a low initial K factor blended polyol with HCFC-141b as blowing agent. The low initial K factor foam made by H467 and MDI has low mould density, good dimensional stability etc. H467 can be used in both high and low pressure foaming machine.
