H815 Blended polyol

  Refrigerators and freezers
  H815 is designed for HFC-245fa blowing system. H815 can be used on high pressure foaming machine.
    Low mould density, good flowing ability
    Good adhesive ability, short demould time
    Low initial K factor, high compressive strength
    Low open cell content on the foam surface, good dimensional stability on low temperature
