Solutia Automotive, a manufacturer of polyvinyl butyral (PVB) interlayer products for glass to the automotive industry, announced 7 May 2003 that Vanceva(TM) Quiet, its advanced acoustic interlayer, is being used in the Rainier, Buick“s latest luxury SUV model. The announcement was made at the Society of Automotive Engineers bi-annual Noise Vibration and Harshness conference in Traverse City, Mich., which ran 5 – 8 May 2003. The conference focuses on testing, analysis and materials technology that increase passenger comfort by reducing unwanted exterior and vehicular noise. “Competition in the automotive marketplace is fierce,” said Jay Pyper, North American market development manager for Solutia. “Consumers demand quality, and quiet is one of the criteria used to judge quality. In fact, the J.D. Power and Associates 2002 Vehicle Acoustic Study showed a clear connection between consumer satisfaction with quietness and satisfaction with the vehicle overall. If automakers can produce a quieter car, that gives them a competitive edge. That is what Vanceva(TM) Quiet offers.” The advanced acoustic interlayer in the windscreen, and laminated glass in the front doors is part of the Buick QuietRide System, developed through careful attention to detail to maximize noise reduction in the vehicle. According to Solutia, normal laminated glass reduces noise intrusion by about 6 decibels compared to tempered glass. Laminated glass is formed by sandwiching polyvinyl butyral (PVB) between two layers of glass. Heat and pressure are applied, causing the PVB interlayer to become transparent. Standard in windscreens for 60 years, laminated glass is now being used more and more in side windows as well because of other benefits inherent to this type of auto glass. Extensive market research and contact with auto engineers at forums like SAE“s NVH conference has demonstrated that laminated glass brings added value to the consumer. In response, Solutia Automotive has brought out several advanced laminates under the Vanceva(TM) brand name, including Vanceva(TM) Color, Vanceva(TM) Metallic, and Vanceva(TM) Quiet. Solutia Automotive partnered with glass supplier Guardian Automotive in the development of the glass for the Buick Rainier. Other benefits of laminated glass include: 10% greater resistance to “smash and grab“ attacks by thieves than tempered glass; protection of passengers and interior materials from UV ray penetration – tests by the Australian Radiation and Nuclear Safety Agency showed a 90% reduction in UV ray penetration with laminated glass versus 60% using ordinary tempered glass, or the equivalent of a 50 SPF sunblock; weight reduction – laminated glass weighs 11% less than comparable tempered glass.
