Newly developed selective self-adhesive silicone rubbers can be co-molded with nylons, polycarbonates, and PBT-type polyesters, creating new design opportunities in medical devices and cars. “These materials can eliminate assembly operations for needle-less IV valves,” comments Eric Bishop of Shin-Etsu Silicones. The new materials’ combinations are also replacing gum rubber in automotive applications. Bishop spoke at Molding 2008 in San Francisco. The materials are called selective because they don’t adhere to steel.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
LeMond Composites, founded by three-time Tour de France cycling champion Greg LeMond, is the first to license a new carbon fiber production method invented by Oak Ridge National Laboratory (ORNL) that's faster, cheaper, and greener.
