Wanwei PVA 24-99(L) & PVA 100-72
Description
Overview
The appearance of PVA is white flake, granular or powdery solid (low-alkali alcoholysis process) or white flocculent solid (high-alkali alcoholysis process). It is a kind of water-soluble polymer with wide application, and its performance is between plastic and rubber. It has unique strong adhesion, film flexibility, oil resistance, surface activity, gas barrier, wear resistance and so on.

Product Application
Processing and Finishing Agent
Polyvinyl alcohol has become the core component of textile finishing agents due to its strong film-forming properties, interfacial adhesion and environmental adaptability. Its role is not limited to improving physical properties (crispness, wear resistance) but also giving fabrics functional properties through chemical modification (acetalization).
Paper Processing
In paper processing, polyvinyl alcohol becomes a multifunctional additive that improves the comprehensive performance of paper through the three-in-one mechanism of "surface film formation-pigment bonding-fiber reinforcement". It has great advantages in terms of strength, printability, water resistance and environmental protection, and is especially irreplaceable in high-end paper and specialty paper.
Adhesive
Polyvinyl alcohol in adhesives has become a multi-scenario bonding solution through the three-in-one mechanism of "polar adhesion-film enhancement-chemical modification". Its core value lies in safety and environmental protection, broad-spectrum bonding, and easy modification, and it is especially suitable for cellulose substrates.
Forming Board Adhesive
Polyvinyl alcohol has become the core adhesive in molding board adhesives due to its high bonding strength, adjustable water resistance and environmental safety. It is particularly suitable for scenes such as gypsum boards and wood chip boards that require both mechanical properties and environmental friendliness.
Package
25 kg/bag.
Storage
