H577 Blended polyol (low density)

  Refrigerators and freezers.
  H577 is designed for cyclo-pentane blowing system. H577 can be used on high pressure foaming machine.
  Low mould density
  Good adhesive ability
  Good demould ability, high compressive strength, good flowing ability
  Less open cell content on the foam surface, good dimensional stability in low temperature
