Wanwei PVA 20-92(L) & PVA 092-35
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
Paper Adhesion
Polyvinyl alcohol achieves efficient, environmentally friendly and multifunctional bonding effects in paper bonding through its unique molecular structure (rich in hydroxyl groups) and physical and chemical properties.
Office Glue
Polyvinyl alcohol is used in office glue, replacing traditional glue. It is safe and non-toxic and suitable for bonding paper products and cartons.
Self-adhesive
Polyvinyl alcohol is mainly used as a functional additive in self-adhesive adhesives, improving overall performance by adjusting rheology, enhancing adhesion, stabilizing colloid structure and improving film-forming properties.
Emulsifier
Polyvinyl alcohol plays a dual role as an interface stabilizer and a structural enhancer in emulsifiers. Its performance can be precisely controlled by the degree of alcoholysis, degree of polymerization and compounding strategy.
Package
25 kg/bag.
Storage
