Less is more

  • LANXESS is developing halogen-free, flame-retardant plastics for thick-walled components
  • Focus on applications in the field of electromobility
  • Wide processing window and high-quality component surfaces
  • Exceptionally easy-flowing material settings in the future, too

Cologne, September 22, 2021 – LANXESS is expanding its range ofhalogen-free, flame-retardant, glass-fiber-reinforced polyamide 6compounds to include Durethan BKV30FN01 and DurethanBKV30FN04 DUS064. Both products are designed for use in thickwalledcomponents with specially optimized requirements regardingfire resistance. Potential applications include power tools, householdappliances and industrial equipment. “These structural materials alsooffer outstanding potential in the field of electromobility and itsperiphery – for components such as thick-walled battery covers orcharging plugs and the associated connector holders,” saysAlexander Radeck, expert in flame-retardant plastics at LANXESS.

The new products are derived from Durethan BKV30FN04, which isalready successfully deployed in the mass production of flameretardantcomponents. This compound meets the requirements of theUL 94 flammability test of the US testing institute UnderwritersLaboratories Inc., achieving an outstanding V-0 classification with atest body thickness of 0.4 millimeters.

Less flame retardant

Simply summarized, the thinner the wall, the more flame retardant isrequired in the compound in order for it to be eligible for V-0classification. Many components requiring a high degree of flameresistance, however, are much thicker than 0.4 millimeters, whichmeans that they can be manufactured using compounds to whichless flame retardant has been added but that still offer sufficient fireresistance.

Durethan BKV30FN01 and Durethan BKV30FN04 DUS064 are specially designed for components with wall thicknesses of 0.75 - 1.5 millimeters and more. The compounds have a UL V-0 classification with 0.75 millimeters (Durethan BKV30FN01) and 1.5 millimeters (Durethan BKV30FN04 DUS064). “Due to the specially optimized flame-retardant package, the material types offer excellent processability during injection molding. They also ensure high-quality surfaces, even with large, planar component geometries,” says Radeck.

LANXESS is planning to expand the Durethan BKV FN range to include exceptionally easy-flow variants for thick-walled components.
