INV high primary hydroxylated modified polyether polyol P1000 P2000

P-1000 P-2000 is a high primary hydroxylated modified polyether polyol. Compared with ordinary polyether polyols, it has the characteristics of high reactivity, high mechanical strength and good water resistance and weather resistance. Widely used in polyurethane resin synthesis, adhesives, elastomers, coatings, etc.
