PVA 88-100

PVA 88-100 is an ultra-high viscosity polyvinyl alcohol (PVOH) with an alcoholysis degree of 88.0 mole%. It’s widely used for Fiber, Adhesive, Stabilizer, Construction industries.

Water solubility: It is easily soluble in water at room temperature, and the water solution is transparent. It is non-toxic and harmless, and is safe and environmentally friendly.
Chemical resistance: At room temperature, the pH value of its aqueous solution is generally around 5-7, with stable viscosity, and is hardly affected by weak acids, weak bases or organic solvents (esters, ketones, higher alcohols, hydrocarbons), and has extremely high oil resistance.
Mixability: It can be mixed with starch, synthetic resins, derivatives of cellulose and various surfactants, and maintains good stability. However, after long-term storage, stratification may occur.
