PA12 (Nylon 12) vs PP-C (Polypropylene Copolymer)
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.
PP-C (Polypropylene Copolymer)
Polypropylene copolymer (random or block) — better impact resistance at low temperatures than PP homopolymer (PP-H). Random copolymer: excellent clarity for packaging. Block copolymer: high impact for automotive bumpers, containers, and household appliances. Trade names: Moplen (LyondellBasell), Hostalen (LyondellBasell). THE automotive interior/exterior polymer alongside ABS.
