Its shocking to some that the historically brittle, unpaintable, and dimensionally unstable polyolefin family is now a major part of over 14 million bumper systems on the road today. Of course many considered SMC and RIM untenable in their formative years, and it is a tribute to the accellerating pace of change in the automotive industry that such a disparate array of opinions exist. Cost, weight, and assembly savings are the real drivers, however, and as we examine the components of the bumper system, individually and collectively, we find specialty polyolefins overcoming historical limitations and making significant inroads. The combination of specialty polyolefins and advanced thermoplastic processes offers innovative new approaches to integrated bumper systems. Unique combinations of EA/Beam, EA/Fascia, and complete bumper systems can be achieved utilizing filled and unfilled polyolefins and TPO's with coinjection, gas injection, expanding mold, and other material/design/process combinations. Light weight, low cost, and recyclable one piece bumper systems may be targeted with materials ranging from structural long glass PP to design-flexible TPO skins.
