SNP’s aqueous polyvinyl alcohol products for ideal for customers who:
Polyvinyl alcohol’s strong film-forming and binding properties make it ideal for use to strengthen textile yarn and paper. The paper industry uses polyvinyl alcohol to impart oil and grease resistance, as a carrier for optical brighteners and as a binder or co-binder in pigmented coatings.
The high-water solubility of films made from certain grades of polyvinyl alcohol find use in many applications where a sacrificial film is of benefit. For example, as a pre-coat on objects to which fiberglass or epoxy castings are to be supplied. In this application, castings are easily removed after curing by dissolving the film with water to release the mold.
Polyvinyl alcohol is biodegradable under certain microbial conditions. This makes it an attractive polymer for the formulation of barrier coatings for packaging.

Polyvinyl alcohol is a water-soluble crystalline polymer that is widely used to produce water soluble films that are formed into water soluble pouches for pre-weighed fortified vitamin packages for cereals, fish bait, gel packs for laundry detergents and pre-weight packages for herbicides. Pre-weighed packages are convenient and protect workers from exposure hazards. For consumers they are an easy way to use a product without mess.

The aerospace and automotive industries use polyvinyl alcohol to coat products for protection during shipping. The advantage being that customers can rinse their products to remove bugs, grease or grime once received.

SNP’s aqueous polyvinyl alcohol products for ideal for customers who:
Polyvinyl alcohol is a polymeric composed mainly of 1,3-diol linkages [−CH2−CH(OH)−CH2−CH(OH)−]; however, a few percent of 1,2-diols [−CH2−CH(OH)−CH(OH)−CH2−] occur, depending on the conditions for the polymerization of the vinyl ester precursor. Polyvinyl alcohol is produced by the polymerization of vinyl acetate to polyvinyl acetate followed by an alcoholysis reaction to polyvinyl alcohol. The extent of the alcoholysis reaction will result in a specific degree of hydrolysis for the PVA.
The degree of hydrolysis is the ratio of hydrophilic alcohol groups and hydrophobic acetate groups. The ratio contributes to the water resistance of the dried film. The fully hydrolyzed PVA has better water resistance than the partially hydrolyzed PVA.
The degree of polymerization is the expression of the size of the polymer and the molecular weight of the polymer. As the degree of polymerization is increased, you see:
