PC GF30 vs PSU (Polysulfone)
Side-by-side chemical composition and mechanical property comparison.
Overview
PC GF30
Glass-fiber reinforced polycarbonate (30% short glass fiber). Combines PC's inherent impact resistance and transparency with dramatically improved stiffness, strength, creep resistance, and dimensional stability. UL94 V-0 flame rating. Very low moisture absorption (<0.15%) ensures stable properties in humid environments. HDT ~145°C under load. Trade names: Makrolon GF, Lexan GF, TECANAT GF30. Used for structural housings, electrical connectors, automotive lamp bezels, precision jigs/fixtures, load-bearing brackets, and 3D-printed functional parts (FDM).
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.
