Vehicle glazing has evolved from its original task of keeping bugs out of our teeth to the multi-functionality of Enhanced Technology Glass(ETG). ETG, innovative glazing solution, is manufactured through a collaboration between PPG Industries and Saflex, a unit of Solutia Inc. and will be featured on General Motors 2008 full-size passenger vans. “All 12- and 15-passenger vans have Enhanced Technology Glass to help protect passengers during a crash,” said Steve Matsil, Vehicle Chief Engineer- GM Medium Duty Commercial Truck and Full-size Vans. “This specialty glass is located in the rearmost side window positions next to the fourth- and fifth- row passengers. The glass is designed to help mitigate the risk of ejection for passengers seated next to the ETG windows,” The use of ETG by GM in its full-size passenger vans marks the first ever use of this glazing technology in a vehicle. ETG is an advanced glazing system that is an evolution of Safe and Sound laminated glass from PPG, a product currently in use on other GM vehicles for reducing cabin noise. Instead of using standard polyvinyl butyral (PVB), ETG incorporates the Saflex K series high security interlayer — a tough and resilient composite PVB structure especially designed for penetration resistance — which is laminated under heat and pressure between two sheets of PPG’s glass. This creates a glazing system that is stronger and more resistant to tearing and penetration than standard laminated glazing. Pete Dishart, PPG global product marketing manager, said: “We are proud to be the supplier of this innovative glazing technology to GM. We commend the GM engineering team who specified the glazing system to meet the particular needs of these vehicles. The utility of ETG shows how vehicle glazing can provide a variety of solutions to automotive manufacturers and their customers.” The commercial introduction of ETG represents the latest offering in what is nearing a 70 year relationship between PPG and Saflex to bring the latest advances in laminated glazing to the auto industry.
