Excellent flowability, outstanding mechanical properties

New polyamide 6 for overmolding Tepex

Process-optimized material for composite hybrid technology

Hybrid technology based on Tepex continuous fiber-reinforced composites overmolded with Durethan polyamides has tremendous potential in lightweight automotive design as an alternative to metal parts, for example in the fabrication of front ends, brake pedals and seat shells. LANXESS already has a broad range of materials for this type of lightweight design. Together with its subsidiary Bond-Laminates, the manufacturer of Tepex, LANXESS regularly enhances this product range by adding new, tailored material variations, thereby incorporating the experience it has gained in numerous development projects.

Wide processing window, reliable manufacturing process
One current example is a new polyamide 6 compound with 55 percent short glass fiber reinforcement that will be marketed in the future under the name Durethan BKV 55 TPX. The advantage of this material optimized for processing with Tepex is its very good flowability combined with high strength and stiffness. It offers processors a wide processing window. “We see great application opportunities particularly for thin-walled lightweight composite parts with large flow length/wall-thickness ratios,” explains Dr. Martin Wanders, head of Global Applications Development in the High Performance Materials business unit (HPM) of LANXESS.

More flexibility in processing
The high flowability ensures that even very thin, geometrically challenging ribbed structures in areas of the mold far from the gate enter into a permanent material bond with Tepex – which in turn contributes to a reliable manufacturing process. “Furthermore, processors can move production to smaller injection molding machines with lower locking forces to gain greater flexibility in machine selection and production planning,” says Martin Klocke, Business Development manager for lightweight construction in HPM.

LANXESS is a leading specialty chemicals company with sales of EUR 8.3 billion in 2013 and roughly 17,300 employees in 31 countries. The company is currently represented at 52 production sites worldwide. The core business of LANXESS is the development, manufacturing and marketing of plastics, rubber, intermediates and specialty chemicals. LANXESS is a member of the leading sustainability indices Dow Jones Sustainability Index (DJSI World and DJSI Europe) and FTSE4Good as well as CDP’s Climate Disclosure Leadership Index (CDLI).
