PESU/PSU Scrap and Granules
We supply PESU (Polyethersulfone) and PSU (Polysulfone) in both scrap/regrind and granules (virgin, near-prime, reprocessed/compounded). These high-temperature engineering thermoplastics offer excellent heat resistance, hydrolysis/steam sterilization stability, and toughness, making them ideal for demanding, long-life applications.
Key Features
- High heat performance: PSU (Tg ~185 °C), PESU (Tg ~225 °C)
- Hydrolysis & steam-sterilization resistance (repeated autoclave cycles)
- Dimensional stability & inherent flame resistance (grade-dependent UL ratings)
- Good chemical resistance to detergents, hot water, oils, fuels
- Clarity/amber transparency with excellent toughness (opaque/black options available)
- Reprocessable & blend-friendly for cost/performance tuning
Applications : Trusted in high-duty environments
- Medical & labware: instrument trays, sterilizable handles, housings, filter holders
- Water treatment: UF/MF membrane support parts, hot-water contact components
- Automotive & rail: under-hood connectors, pump parts, clips, brackets
- Electrical/Electronics: high-temp housings, coil forms, switchgear (non-live parts)
- Aerospace/industrial: ducts, manifolds, fixtures needing heat + rigidity
Why Choose PESU / PSU Scrap & Granules?
You get premium performance at optimized cost: use virgin or near-prime when certification is critical, and reprocessed/compounded grades where value and durability matter. Our controlled sourcing and QC help ensure consistent melt, colour, and mechanicals for reliable production.
