LANXESS to Spotlight New Flame-retardant PA, Biobased Composite and more at Fakuma


At this year’s edition of Fakuma, focus areas for LANXESS are the market launch of hollow-profile hybrid technology as a lightweight design technology and new halogen-free flame-retardant polyamides and polyesters.
A further spotlight will be on materials and component concepts for the future market “New Mobility” – including, for example, lightweight structural components based on the continuous fiber-reinforced composites Tepex® in the field of car batteries.
With our plastic compounds and composite materials, we want to be a trailblazer in establishing material cycles, conserving resources, and protecting the climate. That is why we are focusing on the industrial use of circular and bio-based precursors and monomers in our production activities,” explains Jan Bender, Head of Marketing for EMEA at the High Performance Materials (HPM) business unit.
Highlights at the Event
A new halogen-free flame-retardant and unreinforced polyamide 6 compound. It passes the UL 94 flammability test from US testing institute Underwriters Laboratories Inc. in all colors with the classification V-0 (0.4 to 3.0millimeters) and was designed as a cost-effective alternative to equivalent polyamide 66 compounds. One of the material’s strong points is its high elongation at break, even when it is freshly molded, which means that components can be mounted immediately after production.
LANXESS is also expanding its range of Tepex® continuous-fiber-reinforced thermoplastic composites with the addition of particularly sustainable variants. In this manner, LANXESS is offering a composite material with a level of quality suitable for large-scale production that is manufactured entirely from natural resources. It features a combination of flax fabrics and bio-based polylactic acid as a matrix material. This yield surfaces with a brown, natural look that emphasize the natural origin of the compound.
Its weight-specific strength is roughly at the same level as that of a conventional Tepex® dynalite, which is reinforced with glass-fiber fabric. With its purely thermoplastic matrix, the new flax composite is fully recyclable, as are its fossil-based Tepex® “siblings.” It takes its place in the product range beside sustainable materials such as a Tepex® dynalite, which has a matrix obtained from recycled polycarbonate water bottles.
The market launch of the hollow-profile hybrid technology from LANXESS has now progressed to such an extent that the company was able to embark on a variety of development projects with customers and has already reached the prototype stage with some of them. The new lightweight design technology enables metallic hollow profiles to be functionalized by means of injection molding. Lightweight components currently in development include cross car beams that boast far greater torsional stiffness and strength than components produced using the “traditional” plastic-metal hybrid technology. The optimization of the process combined with innovative tolerance management means that it is now also possible to functionalize hollow profiles using a reliable process without an internal support element for the profiles.
There are ISCC-certified product innovations in relation to the Pocan®-branded PBT (polybutylene terephthalate) compounds – such as Pocan® ECOB3235 and flame-retardant ECOB4239, both of which are reinforced with 30 percent by weight of recycled glass fibers (mass balance method).
LANXESS will be there at stand 4209 in hall B4. At a press briefing on October 13, the specialty chemicals company will present a new sustainable engineering plastics grade that has a particularly low carbon footprint and meets various aspects of sustainability and circular economy.
