PIN FR polyamide for 3D-printing for e-mobility

Clariant has launched a range of glass fibre reinforced polyamides for 3D-printing which use phosphorus-based PIN flame retardants to achieve demanding fire performance and low smoke toxicity. A PA6 + 20% glass fibre formulation achieves a GWIT (glow wire ignition temperature) of 775°C @ 3 mm, and UL 94-V0 @ 0.4 mm and a PA6/66 + 20% glass fibre formulation meets the EU EN 45545-2 and North American NFPA 130 railway norms. Clariant showcased parts produced using these formulations through 3D-printing at Formnext. The 3D printer filaments are compatible with printers using enclosed or heated chambers. The materials are available in a range of colours and offer mechanical performance including low temperature use (-40°C), wear resistance, impact strength and stiffness and long-term stability to weathering.
