PA66 GF30
Polyamide 66 with 30% short glass fiber — stronger and more heat-resistant than PA6 GF30 due to higher-Tm base polymer. UTS ~190 MPa dry, HDT ~250°C. THE automotive under-hood material for structural brackets. Trade names include Ultramid A3WG6 (BASF), Zytel 70G30 (DuPont), Durethan AKV 30 (LANXESS), Technyl A218 V30 (Domo). Used for engine brackets, radiator end tanks, air intake manifolds, and electrical connectors.

Related materials
PA66 (Nylon 66)
Polyamide 66 — stiffer and more heat-resistant than PA6. Higher crystallinity gives better creep resistance and ~40°C higher melting point (260°C vs 220°C). Slightly more brittle. More moisture-sensitive at saturation than PA6. Trade names include Ultramid A (BASF), Zytel 101 (DuPont), Tecamid 66 (Ensinger). Dominant in US/UK markets. Used for automotive engine components, electrical connectors, gears, cable ties, and industrial bushings.
PC/ABS (Blend)
Polycarbonate + ABS blend — one of the most widely used industrial thermoplastic alloys. Combines PC impact strength and heat resistance with ABS processability and lower cost. Better chemical resistance than pure PC. Properties tunable by PC/ABS ratio. Trade names include Bayblend (Covestro), Cycoloy (SABIC), Pulse (Techpolymers). Used for automotive dashboards, laptop/phone housings, power tool casings, and 3D printing (FDM filament).
PE-UHMW
Ultra-High Molecular Weight Polyethylene — the highest impact-strength thermoplastic. Molecular weight 2-6 million g/mol. Self-lubricating, extremely wear-resistant (15x better than carbon steel), and chemically inert. Used for hip/knee implant bearings, conveyor guides, dock fenders, chute liners, food processing equipment, and ballistic armor (Dyneema/Spectra fiber form).
