H458P Blended polyol

  Continuous panel
  H458P is designed for HCFC-141b blowing system. H458P contains all chemicals including HCFC-141b. Good performance PIR foams can be made by H458P and MDI. The foam flame retardant ability can reach at DIN 4012 B2 grade. H458P is used to produce panels for constructions and it is suit for high pressure foaming machine.
       Good flowing ability, homogeneous density distribution
       Fine cells, high closed cell content
       High compressive strength, good dimensional stability in high and low temperature.
       Short demould time
