PVA 2488 Polyvinyl Alcohol White PVA Powder for Adhesives and Coatings

Product Description

Product Description

PVA is an important water-soluble polymer with a white or pale yellow powder, granular, or flake appearance. This product is non-toxic, odorless, environmentally safe, and possesses excellent chemical stability.

PVA has multiple superior properties: good adhesion and film-forming ability, excellent insulation performance, as well as oil resistance, abrasion resistance, and gas barrier characteristics. As a polyol compound, PVA can undergo various chemical reactions including esterification, etherification, and acetalization.

It is mainly applied in textile sizing, paper coating, architectural coatings, adhesives, and packaging films. It performs particularly well in eco-friendly packaging materials and can be used to produce biodegradable plastic bags and 3D printing support materials. PVA is also widely used in pharmaceuticals, cosmetics, agricultural water retention agents, and other industries, making it an indispensable important chemical raw material in modern industry.
