The specialty chemical company Long will once again have its own booth at the "Fuse Box Meets Dryer-Applications of Plastics in Electronics" conference at the South German Plastics Center. Marc Marbach, Head of E & E Sales at LANXESS 'High Performance Materials (HPM) Business Unit, disclosed: "This year our theme is an inexpensive alternative to polyamide 66 compounds, our applications for structural materials, including batteries for electric vehicles, powertrains And charging infrastructure, as well as our growing number of halogen-free, flame-retardant polyamides and polybutylene terephthalate (PBT). We will also showcase a wide range of services tailored to the needs of the electrical and electronics industry, Support our partners throughout the component development chain. "
New halogen-free polyamide with stable orange coloration
Halogen-free flame retardant polyamide 6, polyamide 66 and PBT compounds include non-reinforced materials and glass fiber reinforced materials with up to 45% by weight. This includes polyamide 6 compounds on finished parts, which are very suitable for unsupervised household appliances due to their high tracking resistance and high glow wire resistance. It also includes metal-free and halide-free products, such as voltage connectors near car batteries and electric power systems that require long-term non-corrosion. All products are free of red phosphorus, so they can be tinted in light tones. Marbach said: "We have now developed formulations with high thermal stability. According to RAL 2003, polyamide 6 types such as Durethan BKV30FN04 can be dyed orange." Orange is particularly important in the safety and functional marking of high voltage electrical and electronic components Plays an increasingly important role.
Halogen-free and high laser transparency
In addition to the automotive industry, laser transmission welding is also increasingly used for the mass production of complex plastic parts in the electrical and electronic fields. As a result, HPM has expanded its product range to include halogen-free flame retardants, glass fiber reinforced polyamide 6 and polyamide 66 compounds. These compounds are laser-transparent and can meet the growing demand for specialty products. Marbach said: "These compounds are equipped with new thermally stable flame retardant packaging, which ensures that there is almost no deposit left in the tool during processing. Polyamide 66 Durethan AKV30FN04LT is an example of these materials, except for high levels of laser In addition to transparency, it also has high tracking resistance. "
Halogen-free flame-retardant polyamide 6 and PBT are powerful alternatives to flame-retardant polyamide 66
The shortage of raw materials has led to supply bottlenecks and major price increases for polyamide 66 compounds and flame retardant materials containing red phosphorus flame retardants. Many manufacturers in the automotive and electronics industries are looking for alternative products. In many cases, many polyamide 6 and PBT compounds in the HPM sector are relatively inexpensive alternatives and are technically compatible with each other. International team leader Tim Albert explained, "We have formed a team to help customers in various industries find alternative materials." Alternative materials may be used for connectors, housing parts, circuit breakers and visible parts in household appliances. In addition, the unreinforced halogen-free flame-retardant PBT Pocan BFN2502 has high electrical tracking resistance and high breaking strain, and is suitable for some of the connectors that still use polyamide 66.
Expected to participate in electric vehicle battery manufacturing
LANXESS customized polyamide and PBT compounds for components in lithium-ion batteries, electric powertrains, and electric vehicle charging infrastructure. They have numerous advantages in terms of cost reduction, lightweight design, functional integration, flame retardancy and thermal conductivity. Potential applications include module covers and covers, high-voltage connectors, housing components for control units, battery holders and dielectric tubes. One example is the high fluidity, high modulus polyamide 6 Durethan BKV45FN04 with 45% by weight glass fiber reinforced material. Thanks to its halogen-free flame-retardant packaging, it has passed UL 94 flammability testing at the highest level of V-0 (0.4 mm).
HiAnt-customized services for the electronics industry
HPM supports customers with custom electrical and electrical services including standards compliance for critical flame retardant testing, tool fill analysis, and plastic-compatible design of thermal components using simulated tools. These services use simulation software that takes into account component geometry, installation, heat input and air convection.
