Polyvinyl alcohol (PVA) is a widely used water-soluble polymer. PVA can be rapidly dissolved in water to form a stable colloid. Its performance is between plastic and rubber. In addition to being used as fiber raw material, it is also widely used in the production of adhesives, emulsifiers, dispersants, films and other products

PVA polymer powder is especially suitable for use as building mortar additive. When used with methyl cellulose ether water-retaining agent, it can improve the flexibility, water retention and adhesion of cement mortar. In addition, it can also reduce the friction of mortar, thus enhancing the working efficiency and quality.

PVA is mainly used in the textile industry for warp sizing, fabric finishing agents, and vinylon fiber raw materials; 107 adhesives, interior and exterior wall coatings, adhesives in the construction and decoration industry; Used as a polymerization emulsifier and dispersant in the chemical industry; Used as a paper adhesive in the papermaking industry; It can also be used in daily cosmetics and high-frequency quenching agents.
