Green and environmentally friendly degradable PVA
The interpenetrating network structure polymer plastic alloy formed by blending modified PVA and modified starch is biodegradable. Films suitable for food packaging, agricultural water-soluble films, containers and disposable consumer products are often produced. The waste can be swallowed by microorganisms in moist soil and degrade into carbon dioxide and water, which is non-polluting to the […]
Application in chemical fiber industry
Polyethylene fiber is also called vinylon in the chemical fiber industry. Vinylon fiber is a valuable functionally differentiated fiber. Water-soluble vinylon fiber has two categories: filament and staple fiber. Water-soluble vinylon filament is an ideal water-soluble fiber. It is a characteristic variety of vinylon. It can have a water-soluble temperature of 0～100℃ and can be […]
The main application of polyvinyl alcohol
Polyvinyl alcohol PVA is a water-soluble polymer with a wide range of uses. Because its performance is between plastic and rubber, it has unique strong adhesion, film flexibility, smoothness, oil resistance, solvent resistance, protective colloid, gas barrier, abrasion resistance and special treatment. Water resistance, non-toxic and harmless, so in addition to being used as fiber […]
Water-soluble PVA film
Water-soluble PVA film is a new type of plastic product that has emerged internationally. It uses the film-forming properties of PVA, water and biodegradability, and can be completely degraded into CO2 and H2O. It is a veritable green, high-tech and environmentally friendly packaging. Material. In Europe, America and Japan, water-soluble PVA film has been widely […]
Application of pva in papermaking
PVA has strong adhesion to cellulose, good film-forming properties, and high film strength. PVA is mainly used as paper surface sizing agent, pigment binder and beating machine additive in the paper industry. It can improve the abrasion resistance, folding resistance and tear resistance of paper, and improve gloss, smoothness and printing adaptability. Not only the […]
Application of PVA in Vinylon Fiber
Vinylon fiber is a synthetic fiber produced with PVA as a raw material, including vinylon staple fiber, vinylon long fiber, high-strength high-modulus, medium-strength middle-mode, water-soluble fiber and other varieties. Among them, high-strength and high-modulus fibers have high strength and modulus, strong fiber tension, and good overall performance. They are widely used in building materials, rubber […]
Excellent properties of PVA
Soluble PVA is soluble in water, the higher the water temperature, the greater the solubility, but it is almost insoluble in organic solvents. The solubility of PVA varies with the degree of alcoholysis and degree of polymerization. PVA with partial alcoholysis and low polymerization degree dissolves extremely fast, while PVA with complete alcoholysis and high polymerization […]
PVA film manufacturing
PVA is the only vinyl polymer that can be used by bacteria as a carbon source and energy source. Under the action of bacteria and enzymes, it can degrade 75% in 46 days. It is a kind of biodegradable polymer material and can be produced on a large scale by non-petroleum routes. , The price […]
Pharmaceutical grade polyvinyl alcohol
Pharmaceutical grade polyvinyl alcohol, different from chemical grade polyvinyl alcohol, it is a very safe polymer organic substance, non-toxic to the human body, no side effects, and has good biocompatibility, especially in medical treatment such as its water-based gel It is widely used in ophthalmology, wound dressings and artificial joints. At the same time, polyvinyl […]
Application of polyvinyl alcohol
Polyvinyl alcohol is an important chemical raw material used in the manufacture of polyvinyl acetal, gasoline-resistant pipes and vinylon, fabric treatment agents, emulsifiers, paper coatings, adhesives, glues, etc. On May 30, 2019, a latest international study found that polyvinyl alcohol contained in ordinary glue can be used in the culture of hematopoietic stem cells. On […]
