Long fiber reinforced thermoplastics (LFT)

What are long fiber reinforced thermoplastics?

Long Fibre reinforced thermoplastic (LFT) forms by fibres of granulate length which are subjected to the so-called pultrusion process. In this process the fibre strands are continuously drawn through a polymer melt, embedded in the polymer matrix and finally granulated after cooling. The impregnation quality determines the subsequent component quality. So different combinations of polymer matrix and fibre material result in a large variety of possible LFT materials.

  • Impregnation of individual fibres in Pellets
  • consistent quality
  • No wear/tear of screws and barrels
  • Easily processable on standard injection modling machines
  • wide range of grades

Product portfolio

Long-fiber-reinforced thermoplastics (LFT) are mainly processed by injection molding and enable weight reduction while maintaining high load-bearing capacity for complex components. For this reason, they are of great importance not only for the automotive sector.
