Glass is an ancient building material. With the rapid advancement of modern technology and the ever-changing application technology, various unique glass have come out and thrived the glass family.
An aircraft manufacturing company in the UK invented a non-broken glass for use on an airplane. It is a multi-layer glass with a crumb-bonded transparent plastic film. This polyurethane-based plastic film has a viscous semi-liquid consistency, and when someone tries to break it, the blown polyurethane film will slowly gather together and restore its unique integrity. This glass can be used in cars for anti-theft vehicles.
