#Envalior , a global leader in Sustainable & High-Performance Engineering Materials, has announced a Memorandum of Understanding (MoU) with #SECARA , a fast-growing technology scale-up specializing in the development of industrial-scale solutions for closed-loop #polymerrecycling . Through this collaboration agreement, Envalior will work with SECARA to test and validate pathways to incorporate high-quality post-consumer-recycled (PCR) content into technical material grades based on SECARA’s novel #catalyticdepolymerizationprocess . "Circularity is one of the defining shifts facing the automotive industry, and it can only be solved through strong partnerships across the value chain. With SECARA, we want to explore early what a scalable, high-performance circular pathway could look like and ensure Envalior is ready to support our customers as the ELV requirements take place,” says Christophe Cazabeau, EVP Performance Materials at Envalior. Helping automotive players meet End-of-...

Amcor , a global leader in developing and producing responsible #packagingsolutions , has announced the installation of state-of-the-art automated manufacturing lines and vision inspection systems for #healthcarebag production at its Mundelein, Ill. facility. Amcor’s investment demonstrates significant advancements in packaging reliability and safety.

TENGs are devices that turn everyday motion—pressing, bending, tapping, walking, vibrations—into electricity. They work using the triboelectric effect: when two different materials touch and separate, they exchange charges. That charge imbalance creates a voltage that can drive current through a circuit. Because TENGs can harvest energy from small, low-frequency motions, they’re exciting for self-powered wearables, sensors, e-skins, IoT nodes, and energy harvesting from human movement and ambient vibrations. ✴️ 𝐖𝐡𝐲 𝐟𝐥𝐞𝐱𝐢𝐛𝐥𝐞 𝐩𝐨𝐥𝐲𝐮𝐫𝐞𝐭𝐡𝐚𝐧𝐞 (𝐏𝐔) 𝐟𝐨𝐚𝐦? PU foam isn’t just “soft.” Its 3D porous network means charges can build not only on the surface, but also inside pores during ...

Any EDM marks, milling traces or microscopic imperfections can become visible on the final transparent part. 🧱 The right steel selection Using high quality mold steel with excellent polishing capability is essential. Steels such as 1.2083 / 420 stainless stee...
