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.

LANXESS introduces flame-retardant thermoplastic composite materials with a PA 6 matrix
Tepex proves to be highly flame retardant in specific fire tests. Helene Friesen documenting.
However, for some applications a V-0 classification in the UL 94 flammability test from the US testing institute Underwriters Laboratories Inc. is often mandatory. For such cases, LANXESS has developed three new halogen-free, flame-retardant Tepex variants with a PA 6 matrix.
Sabrina Anders, Project Manager at the LANXESS subsidiary Bond-Laminates, said: “These structural materials are the material of choice when a V-0 classification is required and the components need to have a very high degree of strength, rigidity and energy absorption at the same time.”
Tepex dynalite 102fr-RG600(x)/47% is reinforced with roving glass fibers. 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.
Tepex dynalite 102fr-FG290 is targeted at applications in the electrical and electronics sector. With its reinforcement of fine glass fibre, it produces high-quality surfaces suitable for small housings that are required to comply with the DIN EN 45545-2 standard.
Tepex dynalite 202fr is reinforced with carbon fibres and is intended for components subjected to extreme mechanical stress, such as high-strength electronic housings.
All three structural materials are available in quantities for large-scale applications.
All flame-retardant packages comply with the EU RoHS (Restriction of Hazardous Substances) Directive and the European REACH regulation (Registration, Evaluation and Authorisation and Restriction of Chemicals, Regulation (EC) No 1907/2006)).
In addition to the three new products, LANXESS also offers further halogen-free flame-retardant Tepex variants with polycarbonate-based matrices. Most of these are certified as UL 94 V-0.
