PA12 GF30 vs PEEK CF30: 0% composition overlap. Significantly different materials serving different application areas.
PA12 GF30 vs PEEK CF30
Side-by-side chemical composition and mechanical property comparison.
Overview
PA12 GF30
Glass-fiber reinforced polyamide 12 (30% short glass fiber). PA12 base resin absorbs significantly less moisture than PA6 or PA66 (0.7% vs 2.5-3.0% at saturation), providing more stable mechanical and dimensional properties in humid environments. GF30 reinforcement boosts tensile strength to ~120 MPa and stiffness to ~8.5 GPa. Better chemical resistance than PA6 GF30 against fuels, oils, and brake fluids. Used for fuel lines, automotive under-hood components, cable connectors, pneumatic tubing, sports equipment, and MJF/SLS 3D-printed structural 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.
