Vinyl acetate monomers are hydrolyzed and polymerized to create polyvinyl alcohol (PVA), a synthetic polymer. It is a polymer that dissolves in water and possesses a number of attributes that make it valuable in a variety of settings. PVA is well-known for its superior film-forming abilities, flexib Read More

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 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

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

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

‍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

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

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

What is PVA?PVA, or polyvinyl alcohol, is a synthetic polymer that is tasteless, colorless, and soluble in water. PVA is categorized as a plastic manufactured from fossil fuels since it is a synthetic polymer. To distinguish it from a substance with a similar name, polyvinyl acetate, which is most f Read More

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

PVA is a synthetic resin that is colorless and water-soluble and is mostly used to treat paper and textiles.PropertiesPVA 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 co Read More

PVOH, PVA, or PVAl are synthetic polymers that dissolve in water. Its idealized chemical structure is [CH2CH(OH)]n. As a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, it is utilized in papermaking, textile warp sizing, a variety of coatings, and 3D printing. It Read More

Most of us are familiar with detergent products that come in pods, whether we're washing laundry or running a dishwasher. We'll examine the substance utilized to create these pods, polyvinyl alcohol, in this article.What is polyvinyl alcohol?PVOH, PVA, or PVAl are synthetic polymers that dissolve in Read More

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

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

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
