(Polyvinyl Alcohol Fiber)
Polyvinyl alcohol (PVA) is a water-soluble polymer compound with performance between that of plastic and rubber.
PVA as a water-soluble polymer has a wide range of uses, initially as the main raw material for vinylon fiber, and later gradually developed and applied to the field of non-fiber, expanding PVA application areas and development prospects. The molecular structure of PVA allows it to have numerous unique properties such as water solubility, fiber formation, cohesion, film formation, emulsion stability, dispersion stability, oil resistance, acid and alkali resistance, chemical reactivity, and biodegradability. These special properties determined PVA to be widely used in the production of coatings, adhesives, paper processing agents, emulsifiers, dispersants, films and other products, and the scope of application is widespread throughout textile, food, medicine, construction, wood processing, paper-making, printing, agriculture, steel, polymer chemicals, and other industries. With the continuous advancement of product technology, its applications will be even further broadened in the future.
PVA synthesis methods mainly include the petroleum ethylene method, the natural gas acetylene method, and the calcium carbide acetylene method. Our products utilize the calcium carbide acetylene method to produce PVA.
1) High modulus polyvinyl alcohol (PVA) fiber is an excellent substitute for asbestos fiber and glass fiber.
2) PVA fiber is widely used in construction-related cement-based products, such as fiber cement boards, tiles, pipes, etc.
3) High modulus PVA fiber is used in water conservancy construction projects, instead of steel reinforcements, to provide tensile strength.
4) High modulus PVA fiber can also be used for expressways, airport runways, tunnels, bridges and other construction.
5) Production of high-tenacity ropes, safety nets, etc.
6) Reinforcement for rubber tires, also to be used for conveyor belts, fire hoses, hose preparation, etc.
7) Reinforcement for plastic.
