The Saflex Next Generation Acoustic Interlayer Solution

The demand for enhanced automotive acoustical solutions is being driven by increased environmental noise and the desire that a vehicle be a comfortable oasis where passengers can enjoy a premium sound system or a conversation without the intrusion of outside noise.

Urbanization and the rise in noisier diesel vehicles contribute to the environmental sound level.

In response, Saflex is introducing our next-generation acoustic interlayer which provides significant benefits to laminators, automakers and consumers:

- The Saflex next generation acoustic interlayer consists of a soft middle layer providing enhanced acoustical dampening surrounded by outer layers that provide the handling and fabrication ease of traditional interlayers.

- Saflex next generation acoustic interlayer provides laminators with superior handling and processing characteristics. Not only does it offer easier handling when compared to monolayer products, but its unique structure provides excellent performance and edge stability.

- Use of the product enables engineers to create vehicle interiors that are up to six decibels quieter than they would have been with standard tempered glass a noticeable difference.

- Our Saflex acoustic interlayer is a 'drop in' solution for automakers. For windscreens, the acoustical PVB is essentially the same thickness as the PVB used in a traditional laminated glass window. For other vehicle glazing locations acoustical laminated glass can be directly substituted for either non-acoustical laminates or for non-laminated (tempered) glazing. Automakers also value the fact that laminated glass weighs approximately 11% less than tempered glass of the same thickness.

Samples of the new product are presently available, and laminator testing has demonstrated exceptional results. Commercial quantities of the new product will be made available in the spring of 2007.

Quieter interiors without any fears of ‘ghosting'

The demand for Head Up Display or “HUD” technology has increased over the past several years, due to the innovation of Global Positioning Systems (GPS) technology.

For designers seeking the most advanced HUD interlayer products, Saflex introduces its next generation HUD inter¬layer, a product that uniquely provides the highest quality projected image in the market as well as offering the advanced benefits of Saflex acoustical interlayer.. These benefits are achieved while maintaining the superior durability provided by traditional Saflex interlayer.

Since windscreens are made up of two pieces of glass that are not flat or perpendicular to the driver's eyes, the virtual image must be corrected to ensure that it is sharp and easy to read (no ‘ghosting'). A Head Up Display system utilizes the optical combining characteristics of HUD interlayer to provide a single focused virtual image appearing near the front of the vehicle. The HUD display en¬hances the overall driving experience by allowing drivers to keep their 'eyes on the road' while still viewing critical vehicle data.

Through the use of a proprietary process, Saflex acoustic HUD interlayer is made with non-parallel surfaces to create a windscreen that acts as the optical combiner of the HUD system. With a cross section unique to each HUD system, Saflex HUD and acoustical HUD result in the highest quality projected image in the market.
