Wanwei PVA 23-99(H) & PVA 100-50(H)
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
Building Glue
Polyvinyl alcohol has become a core component for improving construction quality in building glue through three mechanisms: hydrogen bonding, rheology regulation and water retention and film formation. It is mainly reflected in enhanced bonding, optimized rheology, improved water retention and improved environmental performance.
Textile Sizing
With its three core values of strong film-forming, precise adhesion, and environmentally friendly desizing, polyvinyl alcohol has become the "gold standard" for modern textile sizing, with characteristics such as dynamic protection, technological innovation, and sustainability.
Colloid Protective Agent
With its amphiphilic molecular structure and adjustable physical parameters (alcoholysis degree, polymerization degree), polyvinyl alcohol achieves efficient stabilization in colloidal protective agents through the triple mechanism of "adsorption-film formation-space barrier". Its successful application in the fields of paper coatings, emulsion polymerization, building material slurry, etc. has not only improved product performance (such as storage stability and construction uniformity), but also promoted the development of green chemical industry (non-formaldehyde, degradable).
Stabilizer
The core value of polyvinyl alcohol in stabilizers lies in its multiple stabilization mechanisms: through interface protection, surface activity regulation and thickening effect, it ensures the long-term uniformity of emulsions and suspensions.
Package
12.5 kg/bag.
Storage
Avoid generation or accumulation of dusts. Take precautionary measures against static discharges, earth/ground all equipment. Avoid contact with heated or molten product. Do not breathe dust, fumes or vapors from heated product. Use local exhaust ventilation in processing area. Take precautionary measures against direct sunlight and rain drenching during transport. Keep transportation vehicle clean. Avoid packaging destruction and keep away from impurity.
