PVB( Polyvinyl Butyral Resin)
Applications
- 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.
- It is used to create metal bottom coatings and cold paint with strong adhesion and water resistance with strong adhesion and water resistance.
- 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.
- Used to make fabric treatment agents and gauze tube. The food industry is used to make toxic packaging materials.
- 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.
- 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.
