Water-soluble film former
Dissolves in water and dries to strong, oil- and solvent-resistant films.
PVA
Polyvinyl Alcohol (PVA) Supplier from China
Polyvinyl alcohol (PVA) is a water-soluble polymer used for fibers and in large quantities in coatings, adhesives, paper processing, textile sizing and emulsion polymerization. SUNCHEM supplies PVA grades with a batch COA on every shipment.

Product overview & key benefits
PVA is made by hydrolyzing polyvinyl acetate. It dissolves in water to form a stable colloid and forms strong, oil-resistant films, with properties between plastics and rubber. Besides fiber (vinylon), it is used in coatings and building adhesives, paper sizing and coating, textile warp sizing, as a protective colloid in emulsion polymerization (PVAc and VAE), and as a raw material for PVB and water-soluble film.
Grades are defined by degree of hydrolysis and viscosity (degree of polymerization). Tell us the grade you use now so we quote the equivalent.
Binder and colloid
Binds pigments and fibers and stabilizes emulsions as a protective colloid.
Specified on your terms
We quote against your hydrolysis, viscosity and volatile limits and send the batch COA for each lot.

Selection & comparison
Choosing the right PVA grade
| Your requirement | What usually works |
|---|---|
| Building adhesives and putty | Fully hydrolyzed grade; viscosity to suit the formulation |
| Emulsion polymerization | Partially hydrolyzed grade as protective colloid |
| Paper and textile sizing | Match the grade and viscosity you use now |
| Replacing an existing supplier | Send your current TDS or COA; we quote against the parameters you approve |
Packaging & storage
Packaging
Tell us the bag size and pallet requirements you need; we confirm the packaging with the quotation.
Storage
Keep bags closed in a dry store; PVA absorbs moisture.
From first email to approved supply
Name the end use
Adhesive, paper, textile, emulsion or fiber: hydrolysis and viscosity follow from it.
Compare the numbers that matter
Degree of hydrolysis, viscosity of a 4% solution, volatiles, ash and pH.
Test dissolution
Dissolve a sample in your own plant conditions; fully hydrolyzed grades need hot water.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
Tell us your requirement. We match the grade.
Tell us your application and the PVA grade you use now, the quantity and the destination port. Add your current specification and we will quote against it.
