PVA Powder

Polyvinyl Alcohol (PVA) resin is a polymer powder, chemical (CH2CHOH)n is a commonly used adhesive, with good film-forming, adhesive, and thermal stability. Its water solubility is related to the degree of alcoholysis.

Features

Solution Stability

Low viscosity aqueous polyvinyl alcohol solutions are stable at room temperature and will not deteriorate on storage.

Solubility

Polyvinyl alcohols 17-88 and 24-88 are partially soluble in alcohols, they can be dissolved in water at room temperature, when the temperature is lower than 10 °, it needs enough time to dissolve, usually 5-10 minutes.

Film Formation

Polyvinyl alcohol has strong intermolecular adhesion, it is easy to form a film, polyvinyl alcohol is colorless and transparent, the surface is smooth.

Application

For all kinds of wall putty, dry mortar, gypsum products, tile adhesive

Improve the adhesion of cement, ash, calcium powder and gypsum.

Used for wall/ceiling finishes and tile adhesives.

Increase fluidity, slow down the surface drying time, prevent the product surface cracking.

Emulsion Paint Production

Adding 1-2kg of polyvinyl alcohol to emulsion paint can effectively improve the flatness of the product, increase the film-forming rate and reduce the amount of emulsion by 5-10kg.

Exterior wall/insulation mortar system

In the exterior wall and thermal insulation mortar, the combination of RDP and PVA will achieve excellent results

PVA is valued for its adhesive . PVA is valued for its emulsifying and film-forming properties. In the cosmetics industry, it is used as a binder or film-forming agent and to enhance the consistency of the oil or lipid portion of cosmetic formulations. It is used in shampoos, masks, cosmetics, skin care products and hairsprays.

In addition to cosmetics, PVA plays a vital role in many areas. It is used in paper coatings, latex paint glue and as a textile sizing agent. It acts as a carbon dioxide barrier in PET bottles and as a plastic backing sheet in adult incontinence and feminine hygiene products. In addition, PVA is used as a water-soluble film for packaging, as a mold release agent due to its non-stick properties, as a fiber reinforcement in gels, and as a material for chemical-resistant gloves.
