Product Description
PVA resin
Usage and application of polyvinyl alcohol: polyvinyl alcohol (PVA) is white powder in appearance, which can be divided into three types: flocculent, granular and powdery; It is non-toxic, tasteless and pollution-free. It is a water-soluble polymer with a wide range of uses. Its performance is between plastic and rubber. PVA has unique strong adhesion, film flexibility, smoothness, oil resistance, solvent resistance, colloidal protection, gas resistance, abrasion resistance and water resistance after special treatment. Therefore, in addition to being used as fiber raw materials, it is also widely used in the production of coatings, adhesives, paper processing agents Emulsifier, dispersant, film and other products are widely used in textile, food, medicine, construction, wood processing, papermaking, printing, agriculture, steel, polymer chemical industry and other industries.
