CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Manufacturer profiles associated with Polyvinyl Alcohol Polymer Chain.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Primarily used as binders in paper coatings, textile sizing, adhesive formulations, and as film-forming agents in various industrial processes where water solubility and biodegradability are required.
Higher hydrolysis degree (98-99%) provides better water resistance and mechanical strength but slower dissolution. Lower hydrolysis (87-89%) offers faster dissolution and better compatibility with other polymers but reduced water resistance.
Yes, food-grade PVA with specific purity standards is used in edible films, pharmaceutical coatings, and food packaging applications where non-toxicity and biodegradability are required.
