PA12 (Nylon 12) vs PP-H (Polypropylene Homopolymer)
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-H (Polypropylene Homopolymer)
Polypropylene Homopolymer — the lightest common engineering plastic (0.905 g/cm³). Excellent chemical resistance (esp. to acids and bases), good fatigue resistance (integral living hinges), and low moisture absorption. Becomes brittle below 0°C. Used for chemical tanks, HVAC ducts, pump housings, food containers, automotive battery cases, and medical lab equipment.
