The change of travel methods, especially the introduction of new energy vehicles, has brought more opportunities for the development of thermoplastics. For LANXESS, this is also a new opportunity for development. In the recent 'Vehicle Engineering Plastics' VDI Conference. At the same time, LANXESS showcased its latest products and technology solutions such as hollow section hybrid technology, new thermal stabilization system to create PA 66 and continuous fiber reinforced Tepex composites.
The rapid development of technologies such as automatic driving, electrification of power transmission systems, and smart logistics will dramatically change the way of travel in the future. This is also an important driving force for the development of Lanxess polyamide, polyester and thermoplastic composites. “ Dr. Martin Wanders, Director of Global Application Development at LANXESS Performance Materials Division explains, 'Our current R&D focus is mainly on materials and technologies for lightweight construction, thermal polyamide and heat Stress polyester for electrical and electronic components, and polyamides with high thermal stability.
Hollow profile instead of sheet metal
The brand new 'Hybrid Profile Hybrid Technology' is a highlight of LANXESS. This technology is an upgraded version of the traditional plastic/metal mixing technology for large-scale production of automobiles. In combination with PA 6 (polyamide) injection molding, it is used with round Shaped or square cross-section hollow metal profiles, not sheet metal. 'Hollow profile dimensions are relatively stable, can significantly increase the torsional stiffness and strength of hybrid parts. At the same time, the material has great application in cross-beam and other structural components. Potential. However, if traditional mixing techniques are used, there is no guarantee that these components will be sufficiently flexible. Martin Wanders said in explaining the market application of this new technology. Compared with traditional plastic/metal mixing technology, the new process is also injection molding. Manufacturers bring more conveniences, such as lower investment in machinery and tools, and a shorter cycle time than standard injection molding. Around the future application of this new technology, LANXESS made further progress at this VDI conference. Explained, got a lot of participants stop and wait.
PA 66 thermal stability up to 230°C
The XTS2 thermal stability (extreme temperature stabilization) technology increases the thermal stability of PA 66 to 230 °C. Martin Wanders stated: 'Even at constant temperatures of 230 °C, important mechanical properties - such as tensile modulus, fracture stress or The impact strength can also be kept at a high level. 'Unlike other thermal stabilization schemes, the system does not exhibit thermal stability differences between 160°C and 230°C. It is reported that XTS2 materials are mainly targeted at vehicles using high-efficiency internal combustion engines. The first of its product portfolio is PA 6 filled with 35% glass fiber reinforced material, which will be sold under the name Durethan AKV35XTS2, making it ideal for the production of components such as intake manifolds with integrated intercoolers. , LANXESS is currently developing another 30% glass fiber reinforced PA 66 and enhanced PA 66, which can be used for blow molding hollow parts such as air ducts in the engine compartment.
Composite material with electromagnetic shielding properties
The Tepex brand of continuous fiber-reinforced thermoplastic composites is another highlight of LANXESS. These materials are becoming increasingly important for lightweight vehicle designs and are increasingly being used in volume production - such as front-end mounting components and bumper beams, brake pedals. , Full load system and fuel tank reinforcement. Henrik Plaggenborg, Head of Applied Technology Marketing and Commercial Development at Tepex Automotive Group, explained: 'We expect these materials to be highly integrated in the production of vehicle-protective vehicle chassis and self-driving cars. There is a huge potential for application. LANXESS is currently developing composite materials with electromagnetic shielding properties, which are particularly suitable for the transmission components of electric vehicles.
Focus on electric mobility
The new mode of mobility brings more opportunities for the development of thermoplastics. LANXESS believes that its advanced plastic products and technologies are in the battery system's charging system and battery holder, the sensors and housing of the motor and the electric vehicle's infrastructure (such as public charging The field of station has broad application prospects. Dr. Anika van Aaken, a new mobile project manager of LANXESS Performance Materials, said: 'Polyester and polyamide provide the most production of connectors and components for the display and control unit of self-driving vehicles. Excellent performance. ' In addition, the mid-range electric vehicle bracket made of flame-retardant PA 6 exhibited during the same period has been fully demonstrated by 45% glass fiber reinforced, non-halogen and easy flowing PA 6 connector housing. Focus on future travel efforts and attempts.
