Application fields of polyvinyl butyral (PVB)

Application field of polyvinyl butyral -- safety glass

For special glass products such as safety glass and bulletproof glass, a film made of polyvinyl butyral (PVB) is sandwiched between the two layers of glass, so that its glass has low-temperature impact, windability, light transmission, light resistance, weather resistance, sound insulation, ultraviolet ray insulation and other properties. When subjected to strong impact, polyvinyl butyral (PVB) can absorb most of the impact energy, so that its glass will not break. The glass added with the membrane has higher transparency, water resistance, aging resistance and other characteristics, and can be used even if it is lower than 60 degrees Celsius. In addition, it can also be used as a transparent material to replace plexiglass

Application field of polyvinyl butyral film decorative paper for porcelain polyvinyl butyral (PVB) is dissolved into 12-14% solution with ethanol and made into a film, which is used for printing decorative paper film of ceramic (or enamel) products. The fired ceramic (or enamel) pattern is bright in color and bright in quality. The decal paper is characterized by convenient use, low cost, greatly reduced Decal process compared with the original small paper, and high color firing rate. At present, most porcelain factories in China have formed relatively regular production lines for standardized production.

Application field of polyvinyl butyral electronic adhesive

Polyvinyl butyral (PVB) contains hydroxyl group, vinyl acetate group and butyraldehyde group, which has high adhesive properties. Phenolic resin was added to the ethanol solution of PVB to make an adhesive which can be used for a long time at 120 ℃. The product has strong adhesion to metal, wood, leather, glass, fiber and ceramics; Glass fiber reinforced plastics can be manufactured to replace steel, aluminum, copper and other non-ferrous metals; The adhesive made by adding this product and curing agent into epoxy resin is commonly used for the bonding and assembly of electronic instrument parts, the bonding of metal and porous materials, emergency repair, etc. it can also be used in the field of electronic ceramics. In the development of ceramic integrated electronic circuits, this product with medium viscosity and low hydroxyl group is used as a ceramic powder binder to enhance the original strength of ceramics.

Application field of polyvinyl butyral copper foil adhesive

Polyvinyl butyral (PVB) and phenolic resin are used to produce copper foil adhesive for the production of copper clad laminates. It has good peel strength and solder temperature resistance and is widely used in various fields.

Application field of polyvinyl butyral self adhesive enameled wire paint

Polyvinyl butyral (PVB) is the main raw material of self-adhesive enameled wire paint. After this enameled wire is wound and formed in the electrodes of motors, electrical appliances and instruments, the coils can be bonded together by themselves as long as they are heated for several minutes at a certain temperature or treated with appropriate solvents, without immersion and drying.
