  • Six Aplications of Polyvinyl Alcohol in Industry


    Eco-friendliness has emerged as a major problem in the modern world due to the increasing worry over the effects of plastic waste on the environment. The water-soluble synthetic polymer known as polyvinyl alcohol, or PVA, is becoming more and more popular since it is environmentally benign. In this Read More
  • Polyvinyl Alcohol and Paper


    Polyvinyl alcohol is widely used in paper industry for its outstanding adhesive force and film-forming property, and its dosage is getting bigger and bigger. As there are more grades of polyvinyl alcohol, Chinese and foreign grades are not the same, and different grades, their properties and uses ar Read More
  • Properties of polyvinyl alcohol


    Polyvinyl Alcohol (PVA) is made from vinyl acetate by polymerisation and alcoholysis, it is a white, stable, non-toxic, water-soluble polymer, powder, flake or flocculent solid. Polyvinyl alcohol contains many alcohol groups, polar, and can form hydrogen bonds with water, so it can be soluble in pol Read More
  • Five methods of polyvinyl alcohol (PVA) modification


    Polyvinyl alcohol (PVA) is a colourless, non-toxic, non-corrosive, biodegradable water-soluble organic polymer. At present, in addition to being used as raw materials for polyvinyl chloride, PVA is increasingly widely used in textile pastes, coatings, adhesives, emulsifiers, films and other industri Read More
  • Role of Polyvinyl Alcohol Powder


    ‍What are the functions of polyvinyl alcohol powder? What applications can it be used in? Product application: 1. Grey calcium-based putty: A very small amount of addition can significantly improve the cohesion strength, adhesion, water resistance of the putty coating, reduce the amount of grey Read More
  • Characteristics of polyvinyl alcohol


    Polyvinyl alcohol (PVA) is made from vinyl acetate by polymerisation reaction and alcoholysis, it is a white, stable, non-toxic water-soluble polymer, it can be quickly dissolved in water to form a stable colloid, water is a good solvent. Polyvinyl alcohol resin (PVA) aqueous solution has good fil Read More
  • Uses of Polyvinyl Alcohol


    1. Warp sizing PVA-based slurry is the most efficient sizing agent in the synthetic sizing agent and fabric processing agent, cotton, hemp, polyester, polyvinyl chloride, viscose fibres with good adhesion, colourless and transparent film, toughness, abrasion-resistant, sunlight-resistant, high mecha Read More
  • Is polyvinyl alcohol safe and climate-friendly?


    PVA is a synthetic resin that is colorless and water-soluble. PVA is distinct from other polymers in that it is not created by the polymerization of monomeric precursor molecules, which are small, single-unit molecules. Polymers are chemical compounds made up of big, multi-unit molecules. Instead, p Read More
  • Recent advances in the study of biodegradability of polyvinyl alcohol (PVA) (Ⅲ)


    3. The study of PVA biodegradation mechanism There are three main types of PVA degrading enzymes, namely PVA oxidase, PVA dehydrogenase, and oxidative PVA hydrolase. The catalytic reaction mechanism of these three types of enzymes will be explored below. The degradation of PVA by enzymes is a comple Read More
  • Recent advances in the study of biodegradability of polyvinyl alcohol (PVA) Ⅱ


    2. PVA degradase In the practical application of biodegradation of polyvinyl alcohol, enzymes tend to be easier to use industrially than microbial formulations, and their results tend to be better. This is mainly due to the PVA degradation microorganisms in the process of degradation of polyvinyl al Read More
  • Recent advances in the study of biodegradability of polyvinyl alcohol (PVA)


    Polyvinyl alcohol (PVA) is a synthetic polymer compound, which is widely used in textile and paper industries. It is easily soluble in water but difficult to degrade under natural conditions, and is a difficult pollutant to degrade in water treatment. Its content in textile wastewater is very high, Read More
  • Properties and Applications of Polyvinyl Alcohol


    Polyvinyl alcohol (PVA), which is essentially made from polyvinyl acetate through hydrolysis, is easily degradable by biological organisms and, in water, is a solubilized crystalline polymer.PVA is an artificial polymer that has been used worldwide since the first half of the 20th century. It has be Read More
