Eastman to Showcase Advanced Glazing Technologies at JSAE World Congress in Yokohama, Japan

Post Time:May 24,2013Classify:Industry NewsView:67

Starting today, Eastman Chemical Company (NYSE: EMN) will showcase advanced automotive glazing technologies at its booth during the 2013 Japanese Society of Automotive Engineering (JSAE) World Congress, held May 22 through May 24 in Yokohoma, Japan.      

Eastman’s booth features the award-winning Saflex® S series advanced solar absorbing polyvinyl butyral (PVB) interlayers, Saflex Q series advanced acoustic PVB interlayers and Saflex® acoustic head-up display interlayer. 

Visitors will be able to participate in several "hands-on" demonstrations, including a solar heat reduction demonstration showcasing the benefits of Saflex S series advanced solar absorbing interlayers. In addition, participants will able to "hear the difference" that Saflex Q series advanced acoustic interlayers make in automotive glazing applications through a new demonstration constructed exclusively for the JSAE event.

Booth Highlights
Advanced acoustic performance from automotive glass with zero weight gain

Saflex Q series advanced acoustic interlayer allows laminators to produce glass laminates with enhanced acoustical properties compared to laminates made with standard polyvinyl butyral (PVB). Compared to non-laminated monolithic glass, Saflex Q Series improves overall sound transmission loss by up to 5dB, especially in the critical windnoise region where the improvement is in the 10dB range. By adopting thinner acoustic windshields, automakers benefit by improved fuel efficiency via lower vehicle weight while maintaining acoustic comfort.

Fuel efficiency and driver comfort improved with Saflex S series solar absorbing PVB

Saflex S series interlayer represents an award-winning breakthrough in the automotive industry with the introduction of a PVB interlayer  that effectively absorbs solar heat transmitted through the vehicle's glazing which reduces air conditioning usage and improves vehicle fuel economy and CO2 emissions.  

Saflex S series has been recognized by Frost & Sullivan with the 2012 New Product Innovation Award for Automotive Glazing Materials. Saflex S series also garnered the Skin Cancer Foundation’s Seal of Recommendation, marking the first, and only time, an automotive-grade PVB has been recognized for its ability to block +99% of UVA and UVB radiation.  The Foundation also notes that most non-laminated, tempered automotive windows are proven to block UVB, but transmit more than 60% of the sun’s UVA. 

Silence ghosting with Saflex acoustic head-up display interlayers

Automakers are increasingly adopting head-up display (HUD) features on vehicles to enhance overall driving experience and minimize driver distraction by allowing drivers to keep their eyes on the road while still viewing critical vehicle data.  Saflex acoustic HUD interlayer by Eastman  ensures the highest quality projected image for each vehicle while improving acoustic comfort via reduced transmission of exterior noise.

Traditional glazing resulted in double images or “ghosting” due to parallel surfaces of glazing.  Eastman, the pioneer of HUD films, developed a wedge-shaped interlayer enabling non-parallel surfaces in HUD applications which eliminates “ghosting” as well as provides the desired  optical correction for a high quality projected image.

Driving performance through material innovation

For decades, Eastman has been a proven supplier to the automotive industry. Our solvents and polymers help formulators make durable, efficient, and spectacular coatings—while our tackifiers, glass interlayers, and plasticizers are found in innovative applications bumper to bumper. We have expanded our offering specifically for tire formulations improving tire attributes such as wet grip, rolling resistance, durability, and handling.   Today, Eastman continues to set industry standards for innovation and backs that up with a reliable supply chain, exceptional technical support, and industry leadership.  Learn more at www.eastman.com/transportation
