Polyvinyl alcohol is an organic compound, white flake, flocculent or powdery solid without taste. Polyvinyl alcohol is an important chemical raw material for the manufacture of gasoline-resistant pipes and vinylon fibers, fabric treatment agents, emulsifiers, adhesives and glues, etc., but

JOYFORCE PVA 1799 has the characteristics of high adhesion, less dosage, high blank rate, low ash content, stable sintering and volatilization, etc., which makes it have great advantages in the use of magnetic products. The quality has been greatly improved. In the

The dissolution of polyvinyl alcohol is a very delicate operation. If the dissolution is not good, micelles or even hard blocks will appear, which directly affects the subsequent operation and product quality. First, the polyvinyl alcohol is dispersed into cold

One of the important uses of polyvinyl alcohol PVA1799 is to produce vinylon fiber. PVA1799 is also used in textile pulp and textile treatment agent to prevent fabric shrinkage and wrinkling. Polyvinyl alcohol will chemically crosslink with thermosetting resin, which

Biodegradable plastics represented by PLA and PBAT have begun to usher in an outbreak, and PVA has also quietly entered the ranks of alternatives to traditional plastics and developed various applications. If made into PVA film to replace traditional plastic

Polyvinyl alcohol (PVA) is a colorless, non-toxic, non-corrosive, biodegradable water-soluble organic polymer. At present, in addition to being the raw material of vinylon, PVA is widely used in textile sizing, coatings, adhesives, emulsifiers, films and other industrial fields. However, the

PVA polymer powder is especially suitable for use as a building mortar additive. It can be used together with the water-retaining agent of hydroxypropyl methylcellulose HPMC to improve cement. Mortar flexibility, water retention, improve mortar adhesion. In addition, the friction of

PVA is unique among polymers (compounds composed of large, multi-unit molecules) because it is not formed by the polymerization of single-unit precursor molecules called monomers. In contrast, polyvinyl alcohol is made by dissolving another polymer, polyvinyl acetate (PVAc), in an

Textile size and fiber polyvinyl alcohol binder, with very good adhesion and film-forming properties, cheap and high quality, mainly used for pulping pure polyester or polyester-cotton yarn, and sometimes used for pulping high counts together with acrylic size of pure

Construction adhesives and adhesives Construction adhesives made from polyvinyl alcohol include putty adhesives, paint adhesive base materials, etc., and their scale accounts for more than 40% of the total. At present, the most widely used are PVA 17-99, PVA 20-99,
