Polyvinyl alcohol also has good uses in coatings. The polyvinyl alcohol aqueous solution is condensed with formaldehyde under the catalysis of hydrochloric acid to form a water-resistant polyvinyl formal polymer compound, which is widely used as interior and exterior wall

In recent years, the development of new biodegradable packaging materials has received extensive attention. Renewable natural polymers have been used to evaluate the biodegradability of end-use products based on polyvinyl alcohol. Polyvinyl alcohol materials are widely used in biodegradable synthetic

Polyvinyl alcohol (PVA) is a high-molecular polymer, made from vinyl acetate (VAC) through polymerization and alcoholysis. It has good adhesion, film-forming properties, oil resistance, and colloidal protection. Pollution-free and degradable characteristics rarely seen in polymer materials. Compared with other chemical

The opening ceremony of the 130th Canton Fair and Pearl River International Trade Forum was held in Guangzhou. This Canton Fair is a landmark international trade event held in a special international environment. Control and economic and social development have

1. Polyvinyl Alcohol has good mechanical properties, high strength, high modulus and low elongation. 2. Strong acid and alkali resistance and chemical resistance. 3. Light resistance: under long-term sunlight, the loss rate of fiber strength is low. 4. Corrosion resistance:

Polyvinyl alcohol (PVA) is a water-soluble polymer. Because of its good adhesion, film-forming strength and pigment dispersibility, it is often used as an adhesive and surface sizing agent in the paper industry. Today, pVA has been successfully used in inkjet

After more than ten years of competitive integration and optimization, the industry is showing a new pattern of optimized production capacity, increased concentration, stable market varieties, slow growth in market demand, high technical barriers, few new entries, moderate competition, and

1.Polyvinyl alcohol (PVA) 3D printing materials PVA has good water solubility, biocompatibility and mechanical properties. As a polymer 3D printing material, it is mainly used as tissue engineering scaffold material, drug loading material, water-soluble support material and soluble mold material.

The main characteristics of PVA Fiber are high strength, high modulus, low elongation, abrasion resistance, acid and alkali resistance, good weather resistance, good affinity and bonding with cement, gypsum and other substrates, and it is non-toxic, pollution-free, and non-toxic. It

Basic characteristics of polyvinyl alcohol (1) Viscosity: Its viscosity varies with variety, concentration and temperature. As the concentration increases, the viscosity value rises sharply; as the temperature increases, the viscosity decreases significantly. (2) Adhesion: Polyvinyl alcohol has strong adhesion to
