Blend Polyols SPC-10081 for Refrigerators

SPC-10081 blend polyols use C-pentane or CP/IP as blowing agent, which applies to refrigerators, freezers, and other insulation        products.        The        characteristics         of        the        products        are        as        follows 1.excellent flowability, the density of the foam is well-distributed, and the thermal conductivity is low

  1. excellent low-temperature dimensional stability and goodcohesiveness;
  2. demould time is 6-8
  3. SPC-10081is withoutC-pentane。
