Toughness, Resiliency and Adhesion of Polyvinylbutyral (PVB) Interlayers with Regards to Impact Resistance

Jean-Clément Nugue, Emmanuel Nourry, Dr Gérard Savineau

The toughness, resiliency and adhesion of PVB interlayers make laminated architectural glass a second to none material for safety glazing. PVB is the strengthening layer used between two plies of glass to produce laminated safety glass. PVB presents quite unique and remarkable characteristics with regards to resistance to impact, durability and ageing. Its high tensile strength and elongation at break combined with its strong tear resistance characteristics and adhesion to glass can provide solutions to many architectural design problems. In vertical or sloped applications, laminated safety glass resists penetration from accidental impact.
