Abstract
A fire resistant and impact resistant transparent laminate comprising at least two spaced parallel sheets of transparent material selected from the group consisting of ceramic glass and polymeric material, at least one optically transparent fluorocarbon polymer modified with polar groups, at least one optically transparent glass or resinous inner layer between said parallel sheets, and at least one layer of an optically transparent intumescent gel on at least one side of said inner layer.
Claims19
A fire resistant, impact resistant and transparent laminate comprising at least two spaced parallel sheets of transparent material and at least one interlayer, said interlayer comprising an optically transparent thermoplastic fluorocarbon polymer, said fluorocarbon polymer being modified by polar groups and having a melting point in the range of about 120.degree. to 300.degree. C., wherein said polar groups are selected from carboxyl groups, urethane groups and hydroxyl groups.
A fire resistant and impact resistant transparent laminate comprising at least two spaced parallel sheets of tempered glass or glass-ceramic, and between said parallel sheets a sheet of an ionomer and at least one sheet comprising a thermoplastic fluorocarbon polymer, said fluorocarbon polymer being modified by polar groups and having a melting point in the range of about 120.degree. to 300.degree. C., said laminate having a thickness of about 50 mils, wherein said polar groups are selected from carboxyl groups, urethane groups and hydroxyl groups.
