DuPont Co., DSM Engineering Materials and Polyplastics Group are among the materials firms in the spotlight at K 2022, Oct. 19-26 in Düsseldorf, Germany.
DuPont's Mobility and Materials unit will focus on sustainable materials and application developments, officials with the Wilmington, Del.-based firm said in a news release.
New developments touted by DuPont include materials for sustainable solutions, automotive electrification, robotics, consumer electronics, sporting goods and footwear.
DuPont's booth at K 2022 will include Future Lab, a section of the stand where designers and engineers can find eco-friendly solutions that are new or have yet to be introduced to the market. These materials include: Hytrel ECO B-brand thermoplastic elastomers made with biomass; Rynite-brand PET based on post-consumer recyclate; low-density Zytel-brand nylon; and foamable grades of Hytrel for weight reduction.
Officials said that Hytrel ECO B delivers performance equivalent to Hytrel grades made from fossil feedstock but with biomass content up to 72 percent by weight. In the auto sector, DuPont will feature DuPont Chemical Bonding, a patented technology that simplifies manufacturing via direct nylon-aluminum joining. Officials said that process produces higher bond strength but is "a common challenge" for automotive and industrial components.
In running shoes, standard and foamable Hytrel is being used in filament uppers, insoles, midsoles and outsoles. One DuPont customer also recently launched patented, foldable swim fins, thanks to an upgrade from Hytrel ECO B.
