1. Physical and chemical properties:
1.1 Brief introduction: Polyvinyl butyral is white solid particle. The film formed by polyvinyl butyral has a good performance, such as high transparency, elasticity, toughness, alkali resistance, oil resistance and impact resistance at low temperature. It has excellent adhesion ability to glass, metal, ceramic powder, plastic, leather and wood. In addition, it can disperse well into pigment and dyestuff. It also has good compatibility with other resins.
1.2 Structure formula:

pvb
