Manufacturer Good Price PVB( Polyvinyl Butyral Resin) CAS:63148-65-2

short description:

Polyvinyl Butyral Resin(PVB) is a product that is contracted by polyvinyl alcohol and butadhyde under acid catalytic. Because PVB molecules contain long branches, they have good softness, low glass temperature, high stretching strength and anti -impact strength. PVB has excellent transparency, good solubility, and good light resistance, water resistance, heat resistance, cold resistance, and film formation. It contains functional groups that can perform various reactions such as acetylene -based saponification reactions, vinegarization of hydroxyl, and sulfonic acidization. It has high adhesion with glass, metal (especially aluminum) and other materials. Therefore, it has been widely used in the fields of manufacturing safety glass, adhesives, ceramic flower paper, aluminum foil paper, electrical materials, glass reinforcement products, fabric treatment agents, etc., and become an indispensable synthetic resin material.

Applications of PVB

1. The thin film is used to make the sandwich materials for safe glass. The safe glass is good and has a high impact strength. It is widely used in the aviation and automobile field.
2. It is used to create metal bottom coatings and cold paint with strong adhesion and water resistance with strong adhesion and water resistance.
3. It is used to create a bright film flower paper, which can replace ceramic flower paper. The resin industry is used to create crusher plastic for non -ferrous metals such as steel and lead, which can be matched into a variety of adhesives. It is widely used for bonding of wood, ceramic, metal, plastic, leather, layer of pressure materials.
4. Used to make fabric treatment agents and gauze tube. The food industry is used to make toxic packaging materials.
5. The papermaking industry is used to make paper treatment agents. In addition, it can be used to manufacture anti -shrinkables, rigid agents and other waterproof materials.
6. It can be used for the tenderness of the printing industry, concave printing, convex printing, silk net printing, heat transfer, because it is dissolved in alcohol and non -toxic, the seal does not remain the odor, which can be used in the food industry that is sensitive to the odor in the food industry. Such as tea/cigarettes. Because the resin is cedic type, it has excellent adhesion on the surface of the glass with a strong yin ion, which is especially suitable for glass plate decoration silk prints.
