LANXESS: Major innovations for sustainable mobile tools

● Economical alternative to polyamide 66 compounds

●New polyamide with high cycle fatigue strength

●New compounds for laser transmission welding

●New development of halogen-free flame retardant polyester and polyamide

At the 2018 German Plastics Industry Fair (Fakuma 2018), specialty chemicals company LANXESS will focus on new mobile tool materials. Jan Bender, Head of Marketing, EMEA Performance Materials (HPM), explains: 'We hope Demonstrate the advantages of our polyamide and polyester compounds, as well as continuous fiber reinforced thermoplastic composites, especially in power train components and electric drive installations.'

LANXESS expects that the number of electrical and electronic components in the car will increase significantly in the future. Bender explained: 'We have provided a wide range of materials for these applications that meet the most important norms and standards in the international electrical and electronics industry, such as fire protection. Performance, electrical performance and eco-environment, and has been successful in the automotive sector. The specialty chemicals company is also focused on the use of polyamide 6 and PBT compounds (polybutylene terephthalate) instead of the current expensive poly The possibility of amide 66.

Polyamide 6 compound replaces polyamide 66 compound

LANXESS will present its new Durethan Performance product line for the first time at Fakuma. Compared to standard products with the same glass fiber content, the polyamide 6 material grade is several times more resistant to fatigue under pulsating loads. 'Other than that, they meet The ever-increasing demands for dynamic long-term durability of plastic engine compartment components,' Bender explained. In addition, it can improve its static mechanical properties, such as tensile strength at high temperatures. Potential applications include air intake systems, oil filters. The cleaning module and parking brake also include a furniture locking system and a power tool housing. Due to the improved mechanical properties, the new product can replace the expensive polyamide 66 compound with the same glass fiber content in many cases.

High transparency in the near infrared wavelength range

LANXESS has developed new polyamide 6, polyamide 66 and PBT compounds, which are particularly suitable for complex molded parts manufactured in series by laser transmission welding. Lasers are used in the near-infrared range, and these materials are high in the near-infrared range. Horizontal transparency. Bender explains: 'With these products, we can meet the growing demand for sensors, control units and display system enclosures that cover applications from driver assistance systems to autonomous driving.' A new product is the halogen-free flame retardant Durethan AKV30FN04LT. According to the Underwriters Laboratories UL 94 (Underwriter Laboratories Inc.) standard, the laser-transparent polyamide 66 achieves the most V-0 (0.4 mm) in the flammability test. Good classification.

Flame retardant compounds make electric cars safer

The large number of electrical and electronic components and high voltages in electric vehicles increase the risk of fire in the event of a technical failure. The V-0 classification of plastics in the UL 94 test increasingly requires the application of this flame retardant compound. LANXESS Development A variety of halogen-free flame retardant polyamides and polyesters meet this requirement and have the advantages of higher long-term heat resistance, tracking resistance or low corrosion tendency in contact with live parts. At Fakuma, The company will showcase a glass fiber reinforced PBT composite that has achieved excellent results in the glow wire flammability test of finished parts (GWEPT, final product glow wire flammability test, IEC 60695-2-11). Also suitable for unattended household appliances in accordance with IEC 60335-1 ('no flame') appliance standards.

Replacing polyamide 66 compound with PBT compound

Another highlight of the halogen-free flame retardant PBT is the unreinforced Pocan BFN2502. It has a high elongation at break of over 7% and is particularly suitable for dimensionally stable and permanently electrically insulating parts. It is suitable for use in halogen-containing flame retardant packaging. Instead of the unreinforced polyamide 66 compound, this is not only for economic reasons, for example, if the water absorption of the polyamide in the part causes dimensional stability problems, the same applies.

Polyamide material for intake supercharged engines

Another focus of LANXESS' work is the development of blowable new polyamide materials for intake supercharged engines. It has become a trend due to its higher efficiency. Bender says: 'Our products range and can Meets the general requirements for intake and clean air ducts and is easy to use for large series of high surface quality processes. ' For example, for polyamide 66.

Durethan AKV320ZH2.0 and polyamide 6 Durethan BKV320ZH2.0, mainly designed for 3D blown blow molding, such as air ducts. The series also includes very soft, super tough polyamide 6 material with a modulus of elasticity of only 210 megahertz. Pa (under equipment conditions). They can be extruded as a single material solution for the production of pressurized air tubes with integrated flexible bellows.
