Long fiber reinforced thermoplastics (LFT)

What are long-fibre-reinforced thermoplastics?

Long-fibre-reinforced thermoplastics are produced by continuous fibres that are continuously drawn through a polymer melt in a process known as pultrusion. They are then cooled and pelletized, or cut to the desired length. Standard length for LFT is 10 – 12mm. Thanks to the many possible combinations of polymer matrix and fibre material, there is a wide variety of LFT materials for a wide range of applications.

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

Long fiber reinforced thermoplastics (LFT)
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.

Long fibre reinforced thermoplastics based on recyclate

SKYi Treei OL1135

SKYi Treei OL1135 is a special light and heat stabilized glass fibre reinforced polypropylene grade for injection moulding and extrusion. It is based on a high percentage of recycled PP. The typical recycled content is about 45%. The glass fibres are chemically coupled to the polypropylene matrix, resulting in excellent mechanical properties.

SKYi Treei MU1166

SKYi Treei MU1166 is a special, long glass fibre reinforced polyamide grade for injection moulding and extrusion. It is based on a high percentage of recycled PA66. The typical recycled content is about 55%. The long glass fibres, which are chemically coupled to the polyamide matrix, offer excellent mechanical properties.

SKYi SN 2006

SKYi SN 2006 is a special Nylon 6 grade with MOS2 additive, for injection moulding.

SKYi ST 5889 BR

SKYi ST 5889 BR is a special super tough PA66 grade, for injection moulding and extrusion.

More special types LFT

Long carbon fibre reinforced thermoplastics (LCF)

Long carbon fibre reinforced thermoplastics (LCF) offer the highest strength and stiffness performance in injection moulding and reduce weight in part creation to increase efficiency. Long fibre reinforced thermoplastics based on PA66, PA6 or PP with varying amounts of carbon fibre.
