K.D. Feddersen Is Your Distributor for CELSTRAN® LFRT from Celanese

Long Fibre Reinforced Thermoplastics (LFRT)

CELSTRAN® is the product series from Celanese for long fibre reinforced thermoplastics (LFRT). Celanese produces CELSTRAN® using special pultrusion technology which ensures that the fibres are fully impregnated, not damaged and have a standard fibre length of 10 mm. The long fibre reinforced thermoplastics have significantly higher strength, rigidity and impact strength than conventional short fibre reinforced plastics and considerably lower creep.

During the injection moulding process, a framework of fibres is created in the workpiece. This framework is extremely resistant to distortion and ensures low warpage and good dimensional stability. CELSTRAN® comprises base polymers made of various thermoplastics (e.g. PA, POM, PP, PPS TPU) along with different fibre materials (glass, carbon, aramid or stainless steel). Thanks to their properties, CELSTRAN® LFRT products are predestined for use as a replacement for metals, for lightweight construction, or for heavy duty applications.

Our Distribution Portfolio for CELSTRAN®


  • Long fibre reinforcement creates a fibre skeleton in the component which easily meets crash-test requirements
  • Impact strength at least twice as high and notched impact strength two to three times higher than for short fibre compounds
  • Mechanical values remain constant over a wide temperature range
  • High heat distortion temperature
  • Low creep, low warpage and shrinkage
  • Standard fibre length: 10 mm


  • Matrix materials: PP, PA, TPU, ABS, PPS, POM, PEEK, PBT (further matrix materials on request)
  • Glass fibre reinforced grades: fibre content 20–60 %
  • Carbon(C) fibre reinforced grades
  • Aramide fibre reinforced grades
  • Stainless steel fibre reinforced grades for electrical shielding
