Polyvinyl alcohol (PVA) resin is a polymer. Ití»s usually a white or slight yellow flocculent, flake, grnular or powdery solid. Its molecular formular is (C2H4O)n. Ití»s non-toxic, insipid, non-polluting. PVA is a water-soluble resin and has good chemical stability. It also has good adhesion, film-forming alibility, insulation, oil resistance, abrasion resistance and gas barrier properties, and has typical chemical properties of polyols. And can make esterification, etherification, acetalation reactions.
PVA application
PVA products have a wide range of uses.
a.In the textile industry, they are mainly used as yarn pulp, fabric finishing agents, and raw material of vinylon fibers.
b.in the construction and decoration industries, pva can be used as mortar cement additives, paint additives for interior and exterior walls, and molding plate adhesives
c. in the chemical industry, PVA can be used as polymerization emulsifiers, dispersants, and raw materials for the production of PVF, acetalal and butyral resins.
d. in lumbering and paper making industries, PVA can be used as adhesives.
e. in agriculture, PVA can be used as soil improvers, pesticide adhesion synergist and PVA film.
Polyvinyl alcohol has excellent film forming, , and properties. It is also resistant to oil, grease and . It is odorless and nontoxic. It has high tensile strength and flexibility, as well as high oxygen and aroma barrier properties. However these properties are dependent on , in other words, with higher humidity more water is absorbed. The water, which acts as a plasticiser, will then reduce its tensile strength, but increase its elongation and tear strength. PVA is fully degradable and is a quick dissolver. PVA has a melting point of 230°C and 180190°C for the fully hydrolysed and partially hydrolysed grades. It decomposes rapidly above 200°C as it can undergo at high temperatures.
PVA is an material but exhibits as the groups are small enough to fit into the lattice without disrupting it.
Uses:Preparation of is the largest use for polyvinyl alcohol in the U.S. and western Europe. Its use as a polymerization aid is the largest market in China. In Japan the major use is vinylon fiber production.
Some other uses of polyvinyl alcohol include:
Adhesive and thickener material in latex paints, paper coatings, hairsprays, shampoos and glues.
Textile agent
barrier in (PET) bottles.
for use as synthetic vessels in flow testing.
Movie and children's play or slime when combined with .
Feminine hygiene and adult incontinence products as a plastic backing sheet.
As a because materials such as do not stick to it.
As a water-soluble film useful for packaging.
As fiber reinforcement in concrete
As a surfactant for the formation of polymer encapsulated nanobeads
Used with polyvinyl acetate to make Elmer's glue
Used in eye drops and hard solution as a lubricant.
Used in protective chemical-resistant gloves
Used as a for specimen collection, especially stool samples
When doped with iodine, PVA can be used to polarize light.

It is mainly used in making polyester, polyester resin, hygroscopic agent, plasticizer, surfactant, synthetic fiber, cosmetics and explosives, as solvent for dyes/inks, antifreeze for engine, gas dehydrating agent, manufacturing resin, wetting agent for cellophane, fiber, leather and adhesive. It can produce synthetic resin PET, fiber grade PET namely polyester fiber, bottle chip grade PET for making mineral water bottle, etc. Also can produce alkyd resin, glyoxal, etc., also used as antifreeze. In addition to being used as anti-freeze agent for automobile, it is also used for conveying industrial cooling capacity, which is generally called refrigerant carrier.
CETEARYL ALCOHOL cas 67762-27-0 Basic information:
Cetearyl alcohol is a white granular or flake solid with special smell. Insoluble in water, soluble in ethanol, ether, and other organic solvents, with the universality of alcohols.
Cetearyl alcohol is obtained from esterification, hydrogenation and fractionation of natural oils. Fatty alcohols are used in cosmetics, plastics, leather, textile, synthetic detergents and other industries. They are suitable for all kinds of cosmetics, and are especially suitable for cream and lotion. Cetearyl alcohol in medicine can be directly used in w / O emulsifier, cream, ointment matrix, hair care and skin care. Cetearyl alcohol also used as raw material of textile auxiliaries in industry.
Technical Grade and Pure Food & Pharma Grades available.

Polyvinyl alcohol is an excellent water-based adhesive. The general product is flake, granular or flocculent. It is not easily� soluble in cold water. Heating is generally required during dissolution. After being finely pulverized and surface treated, it has� better cold water dissolving performance. But because of its thermoplasticity, pulverization becomes particularly difficult. Our� factory adopts a special liquid nitrogen low temperature cooling process to ensure that the powder of the crushed material is� uniform. So that the material has excellent water solubility.
