This is one of the core advantages of thermoplastic composites (TPCs). For most engineers, the picture is clear: CF-PEEK to CF-PEEK, CF-PPS to CF-PPS, same material, same polymer family, fusion bonding through molecular interdiffusion. But what if the counterpart is metal? At first glance, this sounds impossible. Metals do not melt at thermoplastic processing temperatures, and there is no chemical fusion mechanism as in polymer polymer welding. Yet it is possible, and it has now moved from lab studies to real products. 𝗧𝗵𝗲 𝗸𝗲𝘆 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲: 𝘁𝗵𝗲 𝗯𝗼𝗻𝗱𝗶𝗻𝗴 𝗺𝗲𝗰𝗵𝗮𝗻𝗶𝘀𝗺 When welding TPC to metal, the joint is not based on polymer chain diffusion.

Excessive consumption and mass production of clothing have led to alarming textile waste accumulation in ecosystems, causing serious environmental problems. Something as common as a T-shirt or a jacket is made up of multiple components: fabrics, threads, zippers, elastics, buttons, fillings, and dyes. This variety of materials makes recycling a complex and often inefficient process. A viable alternative is to promote the second use of garments — reusing, repairing, and repurposing can be effective strategies to reduce the amount of clothing ending up in landfills. Every small action counts toward more responsible consumption and a future with less waste and more reuse. 🌱 source : David Izquierdo Duarte #Sustainability #TextileIndustry #CircularEconomy #Recycling #PolymericMaterials

In contrast, for RTM or LRTM, it typically takes at least three days to reach such potential, particularly for production injection moulding. - **Versatile Moulding**: Reusable membrane moulds can effectively mould all types of undercut product features. For RTM or LRTM, considering undercut part geometry is often impractical or uneconomical. - **Cost Efficiency**: When comparing traditional single-use vacuum bags to reusable membrane bags, reusable vacuum membranes transform a "consumable expense" into a "capital asset." These advantages highlight the efficiency and economic benefits of adopting reusable cl...

Evonik has officially inaugurated the expansion of its specialty amine production facility in Nanjing on April 21, 2026. This double‑digit‑million‑euro investment significantly strengthens the company’s capability to supply innovative amine‑based additives for polyurethane and epoxy applications, supporting future market development and advancing the company’s long‑term global strategy. Asia in general and China in particular are important growth markets for Evonik, driven by ongoing consumption upgrades and a shift toward more sustainable solutions across diverse applications. In this evolving market landscape, advanced materials such as polyurethane foams and epoxy curing agents play an increasingly important role. Beyond serving Asia, the enhanced production capabilities for the specialty amine portfolio strengthen the company’s global manufacturing network and its access to raw materials. “This inauguration marks more than the launch of new production capacity. It underlines Evonik...

Tomra Recycling has opened its state-of-the-art test and training center in Charlotte, NC, to boost customer support for recyclers across the Americas. Equipped with cutting-edge sorting technologies, the facility offers expanded testing capabilities, advanced training programs, and end-to-end material tracking solutions to optimize recycling operations.
