There’s a resurgence of chrome in trim, door handles, and other decorative touches to impart a high-end, luxury look to new cars. Special grades of Cycoloy polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) resin and Cycolac ABS resin feature low stress and superior adhesion to the metal layer, and are aimed at helping automakers easily incorporate jewel-bright chrome details into designs
Higher yields are especially important due to the relatively high cost of chrome plating. In addition, the use of plated plastic components versus all-metal parts avoids the expense of secondary operations including milling and polishing. Lightweight plastics also help with weight-out for improved fuel economy. Finally, plastics offer greater design flexibility than traditional metal. Chrome plating can be unforgiving in terms of quality. Even the slightest defects can create a negative impression of the entire vehicle. Target applications include exterior trim, interior trim, running boards, wheel covers, roof racks, and mirror housings that require stiffness, impact strength, and processability.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
