· Plastic/metal mixing technology welcomes development
· New Thermal Stability System Creates Thermally Stable PA 66
· Application of continuous fiber reinforced Tepex composites increasingly common
March 14, 2018, Shanghai - Special Chemicals company Lanxess debuted at the 'Vehicle Plastics' VDI Conference in Mannheim, focusing on 'Reshaping the future of high-tech thermoplastics'. 'Automatic driving, automotive Future forms of drivetrain electrification and new logistics concepts are important drivers for the development of LANXESS polyamides, polyesters and thermoplastic composites. 'Dr. Martin Wanders, Director of Global Application Development at LANXESS Performance Materials Division, explains, 'We Current research and development activities focus on materials and technologies for lightweight construction, as well as polyamides for heat-dissipating flame retardants and polyesters for thermally-stressed electrical and electronic components. Another key area is the high thermal stability of poly. Amide. '
Hollow profile instead of sheet metal
The new 'Hybrid Profile Hybrid Technology' is a highlight of LANXESS. This new process and lightweight design technology is the further development of the classic plastic/metal hybrid technology for mass production of cars. (Polyamide) injection molding uses a combination of hollow metal sections with a round or square cross-section instead of sheet metal. 'Hollow sections are relatively stable and can significantly increase the torsional stiffness and strength of the hybrid part. There are great potential applications for structural components such as crossbeams. If traditional mixing techniques are used, the elasticity of these components is not sufficient. 'Wanders said. Like traditional plastic/metal mixing technologies, this new process developed by LANXESS facilitates injection molding. Commercial implementation. The required investment in machinery and tools is very low, and the cycle time is as short as standard injection molding. LANXESS will demonstrate at the VDI Conference to introduce the advantages of the new lightweight design technology.
PA 66 thermal stability up to 230°C
XTS2 thermal stability (extreme temperature stability) is another hot topic of LANXESS. The technology increases the thermal stability of PA 66 to 230 °C. Wanders said: 'Even at 230 °C such constant temperature, important machinery Performance - such as tensile modulus, fracture stress or impact strength can also be maintained at a high level. ' Unlike many other thermal stabilization solutions, the new system does not show a thermal stability gap between 160 °C and 230 °C. XTS2 material is mainly targeted at vehicles using high-efficiency internal combustion engines. The first product in the XTS2 product portfolio is a PA filled with 35% glass fiber reinforcement. 6. The material will be sold under the name Durethan AKV35XTS2, ideal for use with integrated cooling production member's intake manifold and the like are currently being developed by another product comprising 30% glass fiber reinforced PA 66 and enhanced PA 66, which can be used in the engine compartment air duct and the like blown hollow portion.
Composite material with electromagnetic shielding properties
The continuous fiber-reinforced thermoplastic composites of the Tepex brand line are another topic of interest for LANXESS. These materials are increasingly important for lightweight vehicle designs and are increasingly used in volume production – for example, front-end mounting components and bumpers. Beams, brake pedals, full-loading systems and fuel tank reinforcements. Henrik Plaggenborg, Head of Applied Technology Marketing and Commercial Development at Tepex Automotive Group, explained: 'We also saw that these materials are at the height of vehicle-protective vehicle chassis and self-driving cars. Integrated, multi-position seats have enormous potential for application. LANXESS is currently developing composites with electromagnetic shielding properties that are particularly suitable for parts of electric vehicle drive systems.
Focus on electric mobility
The new mode of travel brings a wide range of potential applications for thermoplastics. LANXESS believes that its high-tech plastics are used in battery system charging systems and battery holders, motor sensors and housings, and electric vehicle infrastructure (such as public charging stations). Wide application prospects. Dr. Anika van Aaken, new mobile project manager of the Performance Materials Business Unit, said: 'Polyesters and polyamides provide optimal performance for the production of connectors and components for display units and control units for autonomous vehicles. In addition, LANXESS A medium-sized electric vehicle bracket made of flame-retardant PA 6 will also be on display to highlight the theme of electric mobility. In addition, a connector made of 45% glass fiber-reinforced, halogen-free flowable PA 6 will also be on display. shell.
