VINYLEC K - Nature

Open Data Verified Data

polyvinyl formal is a condensation product of polyvinyl alcohol and formaldehyde as a white or yellowish amorphous solid. Its softening point is higher than that of homologous Acetals (140~150 ℃), strength, rigidity and hardness are larger, and has good bonding performance; In oil resistance, electrical insulation and other aspects are good, good water resistance, alkali resistance, acid resistance; Soluble in formic acid, acetic acid, furfural, phenols, azobenzene and other solvents.

VINYLEC K - Preparation Method

Open Data Verified Data

polyvinyl alcohol was dissolved in water, and formaldehyde was added to react to obtain polyvinyl formal. Alternatively, polyvinyl acetate is dissolved in acetic acid or alcohol, and hydrolyzed and acetalized with formaldehyde under the catalysis of sulfuric acid or hydrochloric acid to form polyvinyl formal in one step. For example, 100 parts of polyvinyl acetate, 200 parts of acetic acid, 70 parts of water are heated to 70 ° C., completely dissolved by stirring, and then 60 parts of formaldehyde (40%) and 4 parts of sulfuric acid are added, reaction at 70 deg C for 24h, and then ammonium acetate neutralization, add water, namely the precipitation of polyvinyl formal, after washing, drying to get the product.

VINYLEC K - Application

Open Data Verified Data

The biggest use of polyvinyl formal is for insulating enameled wire coating, generally to add less than 20% of the soluble thermosetting phenolic resin mixed use. It is a heat-resistant, water-resistant, transformer oil-resistant and abrasion-resistant insulating paint. It can also be used as the surface coating of paper, artificial leather and the inner coating of the storage tank. In addition, it can also be used as an adhesive mixed with phenolic resin for bonding between various metals, wood, rubber, glass laminated plastics and aircraft parts in the aviation industry. Mixed with phenol, can be plasticized extrusion molding, used for cable insulation coating and production of foam. Polyvinyl formal foam products are very hard when dry, once the adhesion of water becomes swollen, and maintain its soft touch of the elastomer state, so often used in cosmetics powder rub, car, washing Products for bathing, photographic films and food containers. It can also be used for printing plates, medical and filter materials, etc. It can also be used for high impact strength and compression elastic modulus of foam plastic, this kind of plastic is used for the middle layer of laminated plastic, and is widely used in aviation industry.

VINYLEC K - Safety

Open Data Verified Data

resin production raw materials, the skin and mucous membranes of the human body have different degrees of stimulation, can cause skin allergic reactions and inflammation; At the same time also pay attention to the harm of resin dust on the human body, long-term inhalation of high concentrations of resin dust, can cause lung lesions. Most of the resin has a common hazard characteristics: open flame, high temperature flammable, and oxidant exposure will cause combustion risk, therefore, the operator to improve the operating environment, the operating area and the non-operating area shall be intentionally drawn apart, automated and closed as far as possible, and ventilation facilities shall be installed. Paper plastic composite bag packaging, 25kg/bag, stored in a cool, ventilated and dry place, to prevent the sun and rain, away from the fire, can be transported by non dangerous goods.

VINYLEC K - Molding Process

Open Data Verified Data

The polyvinyl formal can be processed on a hot rolling machine. It is mixed with rubber in a certain proportion, can be injected and extruded high impact strength, high modulus of elasticity of mechanical products and electrical products. Because polyvinyl formal has high strength, good heat resistance, good solvent resistance, abrasion resistance and excellent dielectric properties, it is an excellent material for insulating paint, and is also commonly used as an adhesive and coating.
