Polyamide 610 Reinforced with 30 % Carbon Fiber — Examid® PA610 CF30

Description

Examid® PA610 CF30 is a partially bio-based polyamide 6.10 reinforced with 30 % short carbon fiber. PA610 is synthesized from hexamethylenediamine and sebacic acid derived from castor oil, which gives approximately 40–50 % bio-based carbon in the matrix. A unique combination for a structural composite: a low carbon footprint plus carbon fiber reinforcement for metal-replacement-class mechanical performance.

Compared with PA66 CF30, moisture absorption at saturation is 2–2.5 times lower (~3 % versus 7 %): part stiffness and dimensional accuracy remain stable in humid and tropical conditions. Compared with PA12 CF30, it wins on strength and modulus but has a lower melting temperature (Tm ~220 °C, HDT/A ~200 °C per ISO 75-2, 1.8 MPa).

Service temperature: up to 130 °C continuous, up to 160 °C short-term. Not suitable for automotive under-hood applications above 150 °C — for such applications see PA66 CF30 or PPA CF.

Key advantages

• Bio-based origin: 40–50 % of carbon from renewable feedstock (castor oil) — a lower carbon footprint in Life Cycle Assessment
• Low water absorption: ~3 % at saturation (vs ~7 % for PA66) — stable geometry and mechanical performance in humid environments
• Carbon fiber reinforcement: tensile modulus ~20 000 MPa, yield strength ~180 MPa — stiffness on par with magnesium alloys at lower weight
• Low density: ~1.28 g/cm³ — 40 % lighter than aluminum and 80 % lighter than steel at equal stiffness
• High crack resistance and fatigue strength under cyclic loading
• Static-dissipative behavior thanks to the carbon fiber — surface resistivity 10⁴–10⁶ Ohm
• Low shrinkage (~0.3 % in the flow direction) — high dimensional repeatability in series molding

Applications

• Sports industry: bicycle frames and components, ski and snowboard bindings, tennis rackets, helmets, protective gear — light weight + stiffness + bio-based origin for the premium segment
• Eyewear and wearables: premium eyeglass frames, watch and fitness tracker housings, AR/VR frames — a combination of strength, lightness and “premium sustainability”
• Professional-grade 3D printing: filaments for FDM/FFF printers (Markforged-compatible niches), functional prototypes and short-run carbon composite parts
• E-mobility and lightweight automotive engineering: brackets, harness holders, high-end interior components with brand ESG labeling
• Marine infrastructure and outdoor equipment: components in contact with fresh and salt water — low water absorption + UV resistance with additives
• Precision engineering: guides, gears, flanges with antistatic requirements and tight tolerances
