H468P Blended polyol

Application:
  Continuous panels
Introductions:
  H468P is a flame retardant blended polyol with HCFC-141b as blowing agent. H468P contains all chemicals except HCFC-141b. The foam made by H468P and MDI has fine cell structures and DIN4102 B2 grade flame retardant ability.
Preponderances:
       Good flowing ability, homogeneous density distribution
       Fine cells, high closed cell content
       High compressive strength, good dimensional stability in both high and low temperature
       Short demould time
