Raw material sourcing by kg
Polyvinyl Alcohol
Define the polyvinyl alcohol grade and intended market before comparing a coating or other permitted-use sourcing proposal.

Define your ingredient input
Polyvinyl alcohol, also called PVOH or vinyl alcohol polymer, is distinct from a polyvinyl alcohol–polyethylene glycol graft copolymer. Confirm the full polymer identity, hydrolysis specification, intended application and destination documents for the proposed grade.
Discuss your procurement requirements
- Does the proposal identify polyvinyl alcohol rather than a graft copolymer or another polymer?
- Which grade, composition and analytical specification describe the actual material?
- Is the intended project a supplement coating, feed premix or another clearly stated use?
- Which process and sample observations are required for the evaluation?
- Which grade-specific and destination-specific documents support the proposed use?
- Can the supplier confirm samples, quantity in kg, packaging, storage, lead time and quotation terms?

Confirm the offered specification, analytical methods, sample arrangements and documentation with the proposed supplier for your intended project.
Supplement-coating project brief
Describe the tablet or supplement format, coating objectives and process to be evaluated. Ask the proposed supplier which actual grade and documentation address the intended use and destination. A manufacturer’s example or brand statement is not a result or approval transferred to another material.
Feed-premix material review
Where a project concerns an ingredient carrier or binder for a feed premix, state the complete preparation and the destination. Review the applicable material documentation separately from a food-coating brief. Food, feed and other industrial uses should not be treated as one unrestricted use category.
Grade and composition comparison
Compare hydrolysis and polymer specification information on a stated analytical basis. Confirm any additional ingredients and the complete material description. Assess each commercial grade against the intended process and the documents available for that proposal.
Procurement questions and answers
Is ordinary PVOH the same as a PVA-PEG graft copolymer?
No. Keep the complete polymer identity and composition separate when reviewing proposals.
How can the proposed supplier and material be assessed?
Request the supplier identity, proposed grade, complete specification and the documents needed for the intended use and destination.
Are food and feed uses universally established for all grades?
Confirm the grade-specific material documentation and destination requirements for the intended food or feed application before comparing proposals.
