PA66 GF30 vs PSU (Polysulfone): 0% composition overlap. Significantly different materials serving different application areas.
PA66 GF30 vs PSU (Polysulfone)
Side-by-side chemical composition and mechanical property comparison.
Overview
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.
PSU (Polysulfone)
Polysulfone — transparent, high-temperature amorphous thermoplastic. Tg 187°C, continuous use to 160°C. Excellent hydrolysis resistance (autoclavable/sterilizable). Good dimensional stability and creep resistance. Positioned between PC (cheaper, lower temp) and PEI (more expensive, higher temp). Trade name: Udel (Solvay). Used for medical devices (sterilizable), hot water plumbing, food processing, membranes (water purification), and aircraft interior panels.
