DJD-105
Product Introduction
HFC-245fa is the foaming agent of DJD-105 blend polyols, the last substitution of CFC-11, which applies to refrigerators and thermal insulation equipments. Except for environmental protection, it also has characteristics as follows,
1、excellent flowability and the density distributing of foam is uniformity.;
2、the foam has good low temperature dimensional stability and cohesiveness;
3、demould time is short.
