PA12 (Nylon 12) vs PEEK CF30
Side-by-side chemical composition and mechanical property comparison.
Overview
PA12 (Nylon 12)
Polyamide 12 — the long-chain polyamide with the lowest moisture absorption of all PA grades (0.1-0.15% vs PA6: 1.5%). Excellent dimensional stability in humid environments. Best chemical resistance among polyamides (oils, fuels, hydraulic fluids). Lowest density of all PA (1.01 g/cm³). Also the dominant 3D printing (SLS/MJF) material. Trade names include Rilsamid (Arkema), Grilamid L (EMS), TECAMID 12 (Ensinger), Vestamid L (Evonik). Used for fuel lines, brake lines, pneumatic tubing, cable sheathing, and 3D-printed functional parts.
PEEK CF30
PEEK with 30% short carbon fiber — the stiffest and strongest injection-moldable thermoplastic compound available. E-Mod ~24 GPa (vs 11 GPa GF30, 4.1 unfilled). UTS ~212 MPa. Electrically conductive (antistatic/EMI shielding). Outstanding wear/friction properties. Trade names: Victrex 450CA30, TECAPEEK CF30 (Ensinger), KetaSpire CF30 (Solvay). Used for semiconductor wafer handling, bearing cages, compressor components, and metal-replacement structural parts.
