Overview LFT / LFRT

Long-fibre-reinforced thermoplastics (LFT/LFRT) can be processed by injection molding and are therefore of great importance not only for the automotive industry with regard to the possibility of weight reduction while maintaining high load-bearing capacity for complex components.

In addition, 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.

Special LFT

The product series are recyclate based long fibre reinforced thermoplastics.

SKYi MU1166is a special utility long glass fibre reinforced polyamide grade, for injection moulding and extrusion. It is based on a high proportion of recycled PA66. The typical percentage of recycled material is about 55%. The long glass fibres, chemically coupled to the polyamide matrix, providing outstanding mechanical properties.

PA66 30 LFT (MU1166)

SKYi OL1135 is a special light and heat stabilized glass fibre reinforced polypropylene grade, for injection moulding and extrusion. The glass fibres, chemically coupled to the polypropylene matrix, providing outstanding mechanical properties.

PP 30 % GF (OL1135)

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