PA6 – Polyamide 6 PA6 GF60

AKROMID® B25 GF 60 LA black (8494)

AKROMID® B25 GF 60 LA black (8494) is a 60% glass fiber reinforced, laser markable polyamide 6. It is characterised by an improved flowability compared to a standard PA 6 GF 60. Furthermore, the material impresses with its high stiffness and strength. It is therefore perfectly suitable for technical applications in industrial engineering and in the automotive industry.
