Germany’s IKV institute for plastics processing at RWTH University held its biannual plastics technology colloquium in early Spring, including showcasing a number of reinforced polyurethane developments in papers, in the colloquium exhibition area and during visits to its laboratories, David Vink went along and tells us what he found.
Polyurethane composites are growing in popularity, as they offer cost-effective alternatives to other composite matrix materials. The growing market for polyurethane composites is helping to drive innovation and there were three papers presented on new PU production technologies at the February 2016 biannual Plastics Technology Colloquium held in Aachen,
The first PU paper was presented by Hubert Ehbing of the PAT processing & application department at Covestro in Leverkusen, on behalf of Ulrich Liman, senior vice president for Covestro innovation management.
Liman pointed to newer developments such as PU/metal composite hybrids and the use of open reinforcement cores such as paper honeycombs (PHCs). He said that using open structures such as these provide further weight reduction compared with solid composite structures, along with improved acoustic and heat insulation.
PHC cores such as these are used in new Smart ForTwo car roof, produced with Hennecke machinery by FS Fehrer in a composite spray moulding (CSM) process, as well as in Crushcore composite exterior bodywork solutions which automotive supplier Magna showed at the…
