Polyvinyl Alcohol (PVOH) Supplier in Malaysia
- Also known as
- PVOH
- PVAL
- Poly(vinyl Alcohol)
Polyvinyl alcohol supplier for paper, textile, adhesive, emulsion-polymer and construction buyers in Malaysia. Also called PVOH, PVAL or poly(vinyl alcohol), this water-soluble synthetic polymer is selected by degree of hydrolysis and solution viscosity rather than by a generic PVA label alone.
Commercial grades cover fully and partially hydrolysed material in low, medium and high viscosity bands, typically supplied as free-flowing powder or granules. Fully hydrolysed grades suit paper sizing, textile warp sizes and tougher dry films, while partially hydrolysed grades dissolve more readily and serve as protective colloids in emulsion polymerisation.
Applications include water-based adhesives and binders, paper surface sizing and coating, textile warp sizing, ceramic binders, construction dry mixes and selected water-soluble film systems. Polyvinyl alcohol is not polyvinyl acetate or consumer PVA glue; those remain separate materials and intents.
Send the required hydrolysis level, viscosity grade or current grade code, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

Polyvinyl Alcohol grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Fully hydrolysed polyvinyl alcohol | free-flowing powder or granules | — | Paper sizing and coating, textile warp sizing, water-resistant films and adhesives where a high degree of hydrolysis supports stronger hydrogen bonding once the film has dried. | Confirm the required pack format with the quotation. |
| Partially hydrolysed polyvinyl alcohol | free-flowing powder or granules | — | Protective colloid in vinyl acetate and other emulsion polymerisations, redispersible powder systems and formulations that need easier cold-water dissolution than fully hydrolysed grades. | Confirm the required pack format with the quotation. |
| Low-viscosity polyvinyl alcohol | free-flowing powder | — | Lower solution viscosity for high-solids coatings, sizing baths and applications where easy flow or spray application is required. | Confirm the required pack format with the quotation. |
| Medium-viscosity polyvinyl alcohol | free-flowing powder | — | General-purpose binder, thickener and film former for adhesives, paper coatings, textile sizes and construction dry mixes. | Confirm the required pack format with the quotation. |
| High-viscosity polyvinyl alcohol | free-flowing powder | — | Stronger viscosity build and film strength at a comparable solids level for adhesives, ceramic binders and selected water-soluble film systems. | Confirm the required pack format with the quotation. |

Polyvinyl Alcohol applications
Safety and handling
Store sealed in a cool, dry place and protect the powder from moisture. Minimise dust when opening and charging containers, and follow the safety data for the quoted grade and the site's handling procedures.
Common questions about polyvinyl alcohol
What is the difference between fully and partially hydrolysed polyvinyl alcohol?
Fully hydrolysed grades retain fewer residual acetate groups and generally form tougher, more water-resistant dry films, which suits paper sizing, textile warp sizes and many adhesives. Partially hydrolysed grades dissolve more readily in cold water and are widely used as protective colloids in emulsion polymerisation. State the application and dissolution method so the correct band can be quoted.
How should I specify the viscosity grade?
Viscosity figures are only comparable on the same test basis. Send the target viscosity with solution concentration, temperature and method, or the current producer grade code. Low, medium and high labels are not interchangeable between producers, so the quotation should be matched to the full specification rather than a bare band name.
Is polyvinyl alcohol the same as PVA glue or polyvinyl acetate?
No. Polyvinyl alcohol (PVOH) is the water-soluble vinyl alcohol polymer. Polyvinyl acetate is a different resin, and consumer PVA glue is usually a formulated polyvinyl acetate emulsion rather than solid polyvinyl alcohol powder. Keep this page for PVOH grades; vinyl acetate monomer is a separate product.
Which grade is used for paper sizing or textile warp sizing?
Paper and textile buyers commonly select fully hydrolysed grades for film strength and sizing performance, with viscosity matched to the bath solids and machine conditions. Send the current size recipe, target viscosity and any residual acetate limit so a suitable grade can be proposed.
Can polyvinyl alcohol be used as a protective colloid in emulsion polymerisation?
Yes. Partially hydrolysed grades are widely used to stabilise vinyl acetate and related emulsions during polymerisation. State the monomer system, solids target and any preferred grade code with the enquiry so the protective-colloid grade can be matched rather than assumed.
What details are needed for a polyvinyl alcohol price enquiry?
Provide the hydrolysis level, viscosity grade or current grade designation, application, quantity and delivery location. Mention any preferred pack format and documentation needs so the quotation can address the complete requirement.
