Combine a hard polypropylene core and a soft, elastic sealing component and what do you get? For BMW, the material duo significantly cut costs for air duct systems versus previous ducts made of thermoset rubber, copolyester, and polypropylene. The BMW system requires high-temperature resistance and elasticity, as well as long-term properties to ward off chemicals and aging for under-the-hood operation. Using 3D/sequential blow molding, Santoprene thermoplastic rubber from Advanced Elastomer Systems (AES) is molded with a hard polypropylene/glass-fiber material. True to its name, 3D/sequential blow molding enables the production of parts in three dimensions, while allowing molders to change from one material to another during the production of one part. "This application has excellent potential for automotive OEMs around the globe," says Juergen Gloeckler, AES' automotive director, Europe. Advanced Elastomer Systems: Product Code 4375

Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
