We all want to trust “the system” when it comes to issues such as potentially toxic chemicals that could affect our health. But new reports about polycarbonate baby bottles are disturbing. Research from the federal National Toxicology Program is said to raise ‘’some concern” about bisphenol A potentially leaching from polycarbonate baby bottles and other products. Rats exposed to the chemical showed disturbing changes, including some linked to cancer. Canadian health officials say bisphenol A may endanger humans and any may ban the substance from baby bottles. Polycarbonate producers such as Sabic Innovative Plastics are referring questions to Dr. Steven Hentges, a polycarbonate expert at the American Chemistry Council. The ACC has released a very guarded statement, which says that the new studies confirm their position that exposure to BPA is negligible. Dr. Hentges calls on the U.S. government to conduct more studies to affirm the safety of BPA. I wonder what Dr. Hentges is telling his family members about use of polycarbonate baby bottles, which are typically exposed to high heat in a dishwasher? I’ll bet he’s telling them to take no chances. Use safer BPA-free alternatives. Why take any chances? There are limits (big limits) to how far we should go to protect our chemical industry.
It’s not clear to what extent there are also health concerns about epoxy resins, which are typically made with bisphenol A and widely used as a coating in food n beverage cans.
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.
