PSU Rod

PSU rods are an, translucent, amorphous high-performance engineering plastic profile. Known for their excellent heat resistance, hydrolysis resistance, and dimensional stability, they are the most cost-effective basic material in the polysulfone family. Core Performance of PSU Rods** The molecular structure of PSU gives comprehensive properties stability in high-temperature and hydrolytic environments. Keyed 🔥 High-Temperature Resistance**: Can be used long-term within a wide temperature range of -50°C to 150, with high. 💧ional Hydrolysis Resistance**: Can withstand repeated and hot water environments, maintaining stable performance in damp or water-ex. 📏ior Dimensional Stability**: Low water absorption, small thermal expansion coefficient, minimal post-processing deformation—ideal for precision-fit components. ⚡ Electrical Insulation**: Maintains stable dielectric a wide frequency and, suitable for electrical and electronic parts. 🧪 Good Chemical Resistance: Resistant to most acids, alkalis, salt solutions, alcohols, oils, and other organic solvents. ⚠️ Main Weak: Lower impact toughness compared to PPSU ( brittle); poor weatherability—long-term outdoor use causes aging. Primary Applications of PSU RodsLeveraging advantages of heat resistance, hydrolysis resistance, and dimensional stability, PSU rods are widely used in: - Devices: Surgical tool handles, trays, endoscope components, and other parts requiring repeated sterilization. - Food Processing: Pump valves, filters, pipe fittings for food machinery. - **Electronics/ Insulating components, microwave oven parts, connectors, coil bobbins. - ****: Bushings, gears, pulleys, pump valve structural parts, heat-resistant seals.
