Four-dimensional (4D) printing, an extension of 3D printing, incorporates the dimension of time into the fabrication process, enabling the creation of structures that can change shape in response to external stimuli.

4D printing is an evolution in the manufacturing process that incorporates the dimension of time into 3D printing.

Trifluoroacetic acid (TFA) stands out as a promising alternative to per- and polyfluoroalkyl substances (PFAS), known as “forever chemicals,” due to its lower environmental impact while maintaining similar benefits.

Inter Holdings says its patented technology can extend shelf life, save food, and reduce CO2 emissions. A Tokyo-based company has developed and patented what it calls “ultra-high vacuum technology.” It aims to reduce food loss and carbon dioxide emissions while replacing some single-use plastic packaging.

Siloxanes, a group of silicon-based compounds known for their versatility and resilience, are integral to enhancing the performance of plastics. However, their potential health risks have sparked a debate in the EU on the necessity of imposing restrictions on their use.

Companies that produce Fluoropolymers may try to switch to PFAS-free solutions or ask for an exemption, which could be temporary.

The use of “forever chemicals” in the European Union would be largely banned under a proposal issued by the European Chemicals Agency. At the same time, more US states continue to ban PFAS-containing products without a clear roadmap for the…

3D-printed silicone is being used in the development of medical respiratory masks for premature infants. Elkem Silicones, in collaboration with the Hospital Clínic of the University of Barcelona, is pioneering a proof-of-concept project to create 3D-printed silicone masks tailored to the unique needs of premature babies requiring respiratory support.

Use of optical-grade silicone in smart headlights advances with technique from Elmet and Dow.

Datwyler, a manufacturer of system-critical polymer components for diverse industries, is expanding its in-house capabilities with an initiative called Project ETEMI, an acronym for electrically and thermally conductive and electromagnetic interference (EMI) shielding materials.   The Schattdorf, Switzerland, company is using…
