Wanwei PVA 20-88(L) & PVA 088-35
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
Soil Conditioner
Acrylamide (in the form of PAM) has become the "golden component" of soil conditioners through the three core mechanisms of bridging soil consolidation, water absorption and slow release, and nutrient retention. It has the effects of water conservation and drought resistance (building a "solid water reservoir" in the soil, reducing irrigation by more than 50%), anti-erosion and soil stabilization (bonding sandy soil and loose compacted soil, reducing erosion by 78%), and fertility circulation (increasing fertilizer utilization by 40% and activating microbial decomposition activity).
PVA Film
As the core raw material of PVA film, polyvinyl alcohol has shown significant advantages in packaging, medical treatment, agriculture and other fields due to its unique molecular structure and physical and chemical properties.
Warp Yarn Sizing
Polyvinyl alcohol is used as a sizing agent to enhance yarn strength and abrasion resistance, reduce yarn breakage rate during weaving, and improve textile quality.
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.
Package
25 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.
