BYK has developed a new coupling agent for use in polypropylene glass fibre compounds, SCONA TPPP 9212, which is characterised by its very high content of chemically bonded maleic anhydride.
The MA groups of this coupling agent react with the amino groups of the silane of the glass fibre size, thereby producing a very stable structure. The content of 1.8% maleic anhydride is exceptionally high, enabling considerable improvement to be achieved in the compounds’ mechanical properties, even with a low dosage.
SCONA TPPP 9212 is the latest addition to the range of SCONA coupling agents for use in polypropylene glass fibre compounds, which are all based on BYK’s unique solid-phase grafting process. This gentle manufacturing process requires relatively low temperatures and for this reason, is characterised by the reduced number of cleavage products compared to melt grafting. An additional flushing process following the chemical conversion removes volatile components, resulting in the coupling agent having a very low VOC content. This low VOC content permits the processor in turn to manufacture polypropylene glass fibre compounds with extremely low VOC emissions, as demanded by the automotive industry, for example.
Australian organisations Austrak, Laing O’Rourke and the University of Southern Queensland (USQ) have joined forces to develop polymer composite solutions for bridge transoms in a $10 million project titled Polymer Composite Transoms for Rail Bridge Deck Replacement (CompTrans).
Composites One and the Closed Mold Alliance, along with more than 15 industry partners, will demonstrate the latest advancements in closed moulding and advanced processes for building real-life parts for marine, aerospace and other markets during CAMX 2018 in Dallas, Texas, US, on 16-18 October.
With its new ‘Process Live’ format, processing and manufacturing processes will become a visible focus of this year's Composites Europe exhibition in Stuttgart, Germany, on 6-8 November. Mechanical and plant engineering companies will get together in group exhibits to showcase their technologies in live interactions, enabling visitors to experience sub-processes in a larger context.
