China petrochemical pva powder
Polyvinyl alcohol (PVA) is made from vinyl acetate (VAM) by alcoholysis polymerization, is a kind of water-soluble environmental protection polymer.
Appearance: white powder, odorless, tasteless, with fluidity.
Solubility: Polyvinyl Alcohol Powder (PVA) 17-88 and 24-88 are partial alcoholytic PVA, which can be dissolved in room temperature water.
Thermal stability: PVA soften when heated, no obvious change below 40°, above 160° for a long time heating will gradually coloring, decomposition occurs above 220°, generating water, acetic acid, acetaldehyde, and butenal.

Application fields:
Polyvinyl alcohol (PVA) powder is applied to the powder chemical building materials of all kinds of dry powder putty, dry powder mortar additives and ceramic tile adhesive, stucco gypsum binder, etc., can effectively increase the adhesion of cement, mortar, liquidity and slow down the cement surface drying time, increase the coating work adaptability, to prevent the cracks of cement cloth. Suitable for wall, ceiling decoration and tile lamination, simple to use and excellent effect.
Recommended amount: 0.2-1.0% (polymer powder/cement)
Packing and storage: 20 kg/bag, 1 ton/pallet
Note: polyvinyl alcohol powder products are packaged in paper-plastic composite bags lined with high-density polyethylene plastic bags. PVA products should be protected from moisture and rain during transportation and handled with care to prevent scratches and breaks of the package. It is strictly prohibited to store together with volatile chemicals to prevent adsorption and deterioration.
