PA12 (Nylon 12) vs PC (Polycarbonate): 0% composition overlap. Significantly different materials serving different application areas.
PA12 (Nylon 12) vs PC (Polycarbonate)
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.
PC (Polycarbonate)
Polycarbonate — the transparent high-impact engineering plastic. Amorphous with outstanding impact strength (virtually unbreakable at room temp), optical clarity (~90% light transmission), and good heat resistance (Tg 145-150°C). Trade names include Lexan (SABIC), Makrolon (Covestro). Used for safety glazing, machine guards, automotive headlamp lenses, CDs/DVDs, riot shields, and electronic housings.
