Plastics used in the Manufacture of Laminated Safety Glass

JSGT 1936 V20 T035-T044

The composition and properties of celluloid are outlined. A Method of measuring the brittleness of a. piece of laminated glass is described. It is shown that laminated glass with a celluloid interlayer becomes steadily more brittle on exposure to light and the reason is explained. The composition and properties of (a) celluloid acetate plastic, and (b) of synthetic resins are considered in relation to the manufacture of laminated safety glass. Finally an attempt is made to draw up a list of the requirements of a safety glass interlayer.
