similarity:
The end of the molecular chain used for reaction with isocyanate is hydroxyl terminal.
difference:
Polymer polyol is a kind of vinyl monomer and initiator polymer. Based on ordinary polyether polyols, acrylonitrile, styrene and other polymers are added. Mainly used in the field of soft foam.
Polyether polyols are mainly used in soft foam, hard foam, adhesives, etc., mainly used in polyether polyols, mainly used in polyether polyols.
Polyester polyol is mainly made of dibasic acid and dibasic alcohol by esterification, with high hardness and good adhesion. Mainly used for hard foam, adhesive, elastomer, etc.
