Lanxess has unveiled new flame-retardant thermoplastic composite materials with a polyamide 6 matrix. These are for applications, such as housings for control cabinets or components of high-voltage batteries for electric vehicles, for which a V-0 classification in the UL 94 flammability test from the US testing institute Underwriters Laboratories is needed. Tepex continuous-fibre-reinforced thermoplastic composites from Lanxess are characterised by their high inherent flame-retardant properties. One of the reasons for this is their high fibre content. They therefore already pass many of the flammability tests required for typical applications without flame protection. However, for some applications such as housings for control cabinets or components of high-voltage batteries for electric vehicles a V-0 classification in the UL 94 flammability test from the US testing institute Underwriters Laboratories is often mandatory. For such cases, Lanxess has developed three new halogen-free, flame-retardant Tepex variants with a polyamide 6 matrix. One of the three materials, Tepex dynalite 102fr-RG600(ⅹ)/47 per cent, is reinforced with roving glass fibres. These can also be arranged multiaxially and thus precisely matched to the load transfer points and load paths in the component. The composite is universally applicable and is suitable for high-voltage components of electric vehicle batteries, such as separator plates, cover plates and control unit housings.
