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

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

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

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

PVA, also known as polyvinyl alcohol, PVOH, cas 9002-89-5, is a solid that can be in the form of white powder, flakes or flocculent. The glass transition temperature is 60 to 85°C. Polyvinyl alcohol contains many alcohol groups, is polar, and can form hydrogen bonds with water, so it can be soluble Read More

Polyvinyl alcohol abbreviated as PVA,PVOH,cas 9002-89-5, is a very widely used chemical material, can be used in textile pulp, vinylon fiber, paper coating agent, architectural coatings, polyvinyl alcohol surfactant, adhesives, PVA film, PVB raw materials, food and medicine, PVA can also be used as Read More
