At the international VDI Congress Plastics in Automotive Engineering 2024 (PIAE), held in Mannheim, Germany, on June 19-21, new plastics company Envalior (created through the merger of DSM Engineering and Lanxess) is presenting material and technology solutions that make cars safer, lighter and more sustainable. Among the highlights is the showcasing of several test specimens to demonstrate the performance of hollow profile hybrid technology (HPH) in lightweight construction.

HPH is a further step-up in plastic-metal composite technology. Instead of steel or aluminum sheets, metallic hollow profiles are reinforced and functionalized with plastic compounds like the company’s families of high-performance Durethan or Akulon nylons 6 and 66. The new technology has been shown to offer weight savings of up to 35%, enables high-precision production with low tolerances and results in rework-free components that, in some cases, have better damping and acoustic behavior (noise vibration harshness) than corresponding components made of steel.
