As a reliable and renowned polymer solutions supplier, ROMIRA has recently developed new lightweight and high strength PA compounds based on re-processed carbon fiber (rp-CF). The rp-CF is produced from residual cuttings/offcuts supplied by leading carbon fiber manufacturers. Consequently, as the fibers are virgin fibers with homogenous properties there is no property fluctuation due to mixed fiber types. This green and sustainable re-processing on prime level, results in up to 90 % less CO₂ footprint compared to prime carbon fiber production.

The PA compounds produced using rp-CF also exhibit excellent mechanical properties. The table presents typical properties of PA6 rp-CF20 (20 % carbon fiber) compared to a commercially available PA6 CF20. This clearly shows that the measured mechanical properties are highly comparable.

As previously mentioned, light-weighting is one of the key areas of interest related to PA compounds. Glass fiber reinforced PAs are used extensively in the automotive industry on account of their low cost and favorable mechanical properties, in particular in terms of impact strength. The table demonstrates that the new PA6 rp-CF20 also offers a standard property level, while achieving a greater reduction in weight than PA6 GF20.
