Triplex made laminated and toughened windscreens and windows for the automotive, rail, marine and aerospace sectors. Particularly widespread is the use of so-called "triplex" adhesives, which result from the bonding of two or more glasses – single or safety – usually via polyvinylbutyric (PVB) membranes. The glazing is welded by heating and ...
