Physical and chemical properties of Polyvinyl Alcohol Fiber
Polyvinyl alcohol resin series products are white solid, the appearance of flocculent, granular, powder three kinds; non-toxic, odorless, non-polluting, can be dissolved in 80-90 ℃ water. Its aqueous solution has good adhesion and film-forming properties; it is resistant to most organic solvents such as oils, lubricants and hydrocarbons, etc.; it has chemical properties such as esterification, etherification and acetalization of long-chain polyols.

Polyvinyl Alcohol Fiber is a high-strength, modulus fiber produced by a special process using polyvinyl alcohol as raw material. It has the advantages of high strength, high modulus, low elongation, good dispersion, acid and alkali resistance, abrasion resistance, UV resistance and corrosion resistance. It also combines well with cement, so it can be used as various types of reinforcing materials. It is now widely used in water conservancy project dams, hydroelectric power generation, basements, harbor projects, concrete slabs and many other construction fields

Polyvinyl Alcohol Fiber is designed for high modulus, high strength, alkali and acid resistance, and heat resistance. With cement and other polymer materials also have good compatibility.
