Michelman is introducing two unique polyurethane dispersions designed as fibre sizing for reinforced composites in automotive under-the-hood applications.
According to Michelman, Hydrosize Link dispersions react directly with the matrix resin, delivering exceptional composite performance under extreme exposure to water, ethylene glycol, and high temperatures, conditions increasingly typical in the narrow confines of modern engine compartments.
According to Dr. Rick Michelman, Executive Vice President, Chief Growth & Technology Officer at Michelman, “Our new Hydrosize Link U470 and U480 fibre sizings are testaments to Michelman’s intense focus on polyurethane synthesis and controlled manufacturing. These new products solve critical problems and challenges encountered by fibre and composite manufacturers. Innovators from across the automotive industry supply chain have asked for specialised solutions that allow them to expand the use of high performance composites. This is what we have delivered. While fibre sizings account for as little as 0.2-0.3% of a finished composite part, Hydrosize Link solutions have an incredible impact on performance.”
Michelman claims that its Hydrosize Link technology eliminates the fibre producer’s step of adding secondary crosslinkers such as blocked isocyanates to the sizing bath. This not only simplifies the fibre manufacturing process, but more importantly it allows better control over the desired degree of reactivity, and ultimately, composite performance. The two new grades differ in their level of reactivity.
Michelman will introduce Hydrosize Link at CAMX 2016, being held 26-29 September 2016 at the Anaheim Convention Centre in Anaheim, California, US. Michelman will exhibit in booth G79.
Composites UK reports that its members are supporting the new 2018-2021 Safety in Manufacturing Plastics and Composites strategy (SIMPLC).
Composites are considered hard to join and researchers have predominantly focused on mechanical joining technologies including crimping, gluing, riveting or screwing. The Composites Europe exhibition in Stuttgart, Germany, on 6-8 November will show the advantages and drawbacks of each of these processes.
The Aachen Center for Integrative Lightweight Production (AZL) and the Institute of Plastics Processing (IKV) at RWTH Aachen University are commencing a study into the use of thermoplastic tapes in injection moulded parts. Companies interested in joining the study are invited to a kick-off event during Fakuma 2018 in Friedrichshafen, Germany, on 18 October.
