Application field of polyvinyl butyral - safety glass

The membrane made from polyvinyl butyral (PVB) is a special product used for manufacturing safety glass and bulletproof glass. Safety glass is a special type of glass made by sandwiched a layer of PVB film between two layers of ordinary glass. It has good low-temperature impact strength, flexibility, light transmittance, light resistance, weather resistance, sound insulation, and UV resistance. When subjected to strong external impacts, PVB membranes can absorb impact energy, preventing this type of glass from breaking or injuring people from fragments. Moreover, safety glass added with PVB membranes has high transparency, water resistance, aging resistance, and can be used in environments of -60 ℃. In addition, it can also be used as a transparent material to replace organic glass.

Application field of polyvinyl butyraldehyde - ceramic thin film floral paper

Dissolve polyvinyl butyral (PVB) in ethanol into a solution of 12-14%, and make it into a thin film. Use it for printing floral paper thin film of ceramic (or enamel) products. The fired ceramic (or enamel) pattern has bright color and smooth texture. The characteristics of this flower paper are easy to use, low cost, greatly reduced sticker process compared to the original adhesive paper, and high color burning rate. At present, most porcelain factories in China have established relatively formal production lines for standardized production, therefore, the demand for PVB in the ceramic (or enamel) paper industry is constantly increasing.

Application field of polyvinyl butyral - electronic adhesive

Polyvinyl butyral contains hydroxyl, vinyl acetate, and butyraldehyde groups, which have high adhesive properties. Phenolic resin is added to the ethanol solution of PVB to make an adhesive that can be used for a long time at 120 ℃. This product has strong adhesion to metals, wood, leather, glass, fibers, and ceramics; Can manufacture fiberglass to replace non-ferrous metals such as steel, aluminum, copper, etc; The adhesive made by adding this product and curing agent to epoxy resin is commonly used for the bonding and assembly of electronic instrument components, the bonding of metals and porous materials, emergency repairs, and 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 groups is used as a ceramic powder adhesive to increase the original strength of ceramics.
