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
The use of PVOH 745 shows a series of advantages, such as: because of the high efficiency of controlling the size of the resin, the amount needed to be added is reduced; Resin fluidity is very good; Better quality and stable performance, bring the stability of customer products
It must be noted that different polymerization formulations, specific designs, and different levels of PVC requirements will reflect different advantages.
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.
