Three new unsaturated polyester resin formulations now available from Ashland reduce weight and improve the painting characteristics of automotive composites.
The new resins, available in one Class A and two low-density structural formulations, are the latest enhancements to Ashland’s Arotran line of resins for the transportation industry.
“Our new formulations are the next generation of ‘tough’ resins,” said Cedric Ball, global market manager, Ashland Composite Polymers. “We achieved toughened Class A performance without sacrificing physical properties. This is also the first toughened resin in a low-density system offering tremendous weight savings to OEMs.”
The new Class A formulation specific gravity measures 1.6, while the two structural formulations boast densities of 1.3 and 1.2. The Class A formulation is claimed to provide excellent paint pop resistance, help decrease scrap and lower overall costs.
The American Composites Manufacturers Association participated in a roundtable discussion about the IMAGINE Act. Known as the Innovative Materials in American Growth and Infrastructure, Newly Expanded (IMAGINE) Act, the new bill is designed to promote the increased use of innovative materials like fibre reinforced polymer (FRP) composites, as well as new manufacturing methods to accelerate the deployment and extend the life of infrastructure projects.
After the collapse of a drinking water pipeline in downtown Amsterdam, the Netherlands, Insituform was contracted to reline a close to 100 year old pipe underneath one of the canals. Water was restored successfully within five days, with minimal impact on traffic and the environment.
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).
