Speciality chemicals group Lanxess (Cologne / Germany; www.lanxess.com) is expanding its range of halogen-free, flame-retardant, glass-fibre-reinforced PA 6 compounds to include “Durethan BKV30FN01” and “Durethan BKV30FN04 DUS064”. Both products are designed for use in thick-walled components with optimised requirements for fire resistance. Potential applications include power tools, household appliances, industrial equipment, and electromobility.

The new products have been derived from “Durethan BKV30FN04”, which is already successfully deployed in the mass production of flame retardant components. The compound meets the requirements of the UL 94 flammability test of testing institute Underwriters Laboratories (Northbrook, Illinois / USA; www.ul.com), achieving a V-0 classification with a test body thickness of 0.4 mm. Recently, Lanxess developed a battery housing for electric vehicles, with Korean auto parts specialist Infac, using Durethan BKV30FN04 (see Plasteurope.com of 31.08.2021).

Durethan BKV30FN01 and Durethan BKV30FN04 DUS064 are designed for components with wall thickness of 0.75-1.5 mm and more. The compounds have a UL V-0 classification with 0.75 mm and 1.5 mm. Lanxess said it is planning to expand its Durethan BKV FN range to include exceptionally easy-flow variants for thick-walled components.
