Application
- Polyvinyl Alcohol (PVA) is a kind of important heavy polymer. It is usually a white or slight yellow floccules, flake, granular or powdery in appearance.PVA is non-toxic, insipid and non-polluting and a kind of water-soluble resin with good chemical stability. It also has good adhesion, film-forming ability, insulation, oil resistance, abrasion resistance and gas barrier properties, and has typical chemical properties of polyols and can make esterification, etherification, acetalization reactions.
- Polyvinyl Alcohol are mainly used for textile warp size, fabric finishing agent and vinylon fiber raw materials in textile industry.In the paper industry, Polyvinyl Alcohol are used for surface sizing and coating. In adhesive formulations, Polyvinyl Alcohol can function as the primary alcohols or a compounding agent.In the construction and decoration industries, Polyvinyl Alcohol can be used as mortar cement additives, paint additives for interior and exterior walls, and molding plate adhesives; In the chemical industry,Polyvinyl Alcohol can be used as polymerization emulsifiers, dispersants, and raw materials for the production of PVF, acetal and butyral resins.. In agriculture, Polyvinyl Alcohol can be used as soil improvers, pesticide adhesion synergist and PVA film;In petroleum exploitation, Polyvinyl Alcohol can be used as well-cementing agents. Polyvinyl Alcohol can also be used in cosmetics, pharmaceuticals, printing, ceramics, steel, electronics, electroplating, and so on.
