H468P Blended polyol

  Continuous panels
  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.
       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
