Overview
Modified polyvinyl alcohol (PVOH) is graded according to different degrees of polymerization, hydrolysis and copolymerization monomers.
The modification of PVA is mainly to use the double bonds, ester groups and the chemical activity of the hydroxyl group after alcoholization of vinyl acetate to change the side chain group or structure, and introduce other monomers to become copolymers dominated by PVA.
General properties
PVOH 8850 can be used for special requirements such as blended resins, paste resins and copolymers of high vinyl acetate, as well as for all grades of general resins.
Package
Packages:In 25 kg/bag.
Storage
Modified PVA for PVC can be stored for an unlimited period of time under appropriate conditions that is in its original packs in closed, dry rooms, at room temperature.
