Advanced Polymer Alloys (APA) introduced a new UV-stable TPE that bonds to engineering plastics. Called DuraGrip TPE 6100, this elastomer offers a color shift of less than 3 delta-E in standard color tests. "Unlike many other engineering thermoplastic bondable TPE products, which can be prone to yellowing, the DuraGrip 6100 Series will not noticeably darken when exposed to ultraviolet light," says Jeff Senich, business development manager for APA. DuraGrip, a SEBS-based TPE, bonds to a variety of engineering plastics, including nylons, PC, ABS, PC/ABS, ASA and more. Typical bond strengths depend on the substrate, but the 6100 Series achieves 19 lb/in on nylon 66 (in 90-degree pull tests). It was designed specifically for overmolding and co-extrusion processing. And with its UV-resistance, it targets automotive and durable goods applications. Other DuraGrip lines include the 6000 general purpose grades, the 6200 Series high-performance grades, and the 6300 extrusion grades.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
