Polyvinyl Butyral PVB Interlayer Film Properties: Safety
Laminated glass with Polyvinyl Butyral PVB interlayer film has strong elasticity. Polyvinyl Butyral PVB interlayer film have impact resistance, and also have penetration resistance, the shatters will be sticked together by the Polyvinyl Butyral PVB interlayer film. And the safety of laminated glass is remained.Whether the laminated glass with Polyvinyl Butyral PVB interlayer film is installed vertically or horizontally,the accident impact on laminated glass with Polyvinyl Butyral PVB interlayer film is still working great. Performance of resistance and penetration of Polyvinyl Butyral PVB interlayer film is better if the thickness of Polyvinyl Butyral PVB interlayer film is more.
