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 735 is the latest generation of polyvinyl alcohol dispersant specially developed for the suspension polymerization of vinyl chloride, which shows a series of advantages, such as: high efficiency in controlling the size of the resin, so that the amount of addition is small; The stability of product quality brings the stability of customer product quality; Resin fluidity is good; Better thermal stability and so on.
PVOH 735 was developed to meet the requirements of PVC manufacturers for the ability to control particle size better than the traditional 72.5% grade at lower amounts of addition, while maintaining all the benefits of this grade of dispersant.
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.
