Polyethersulfone (PES) is a high-performance thermoplastic widely used in medical, aerospace, automotive, and water filtration industries. While PES offers excellent thermal stability, chemical resistance, and mechanical strength, its processing efficiency can be challenging due to its high melting point and sensitivity to moisture. Optimizing processing techniques is crucial for improving productivity, reducing material waste, and ensuring high-quality products. At Polima PES, we specialize in high-quality PES solutions and provide expert recommendations for efficient processing.
Effective Drying: PES is highly hygroscopic and absorbs moisture quickly, leading to defects like bubbles or degradation. Drying at 150–160°C for 3–4 hours in a desiccant dryer ensures a moisture content below 0.02%.
Storage Conditions: Keep PES in sealed containers with low humidity to prevent moisture absorption before processing.
Processing Temperature: PES requires high molding temperatures, typically between 320–380°C, to achieve optimal melt flow. Maintaining a consistent temperature prevents material degradation.
Mold Temperature: Keeping the mold at 140–180°C ensures better flow and reduces internal stresses, leading to improved part quality.
Injection Pressure and Speed: Use moderate to high pressure (80–150 MPa) and a controlled injection speed to avoid defects such as warping or burn marks.
Extrusion Considerations: For continuous production of PES sheets, pipes, or membranes, using multi-zone temperature control in extruders enhances melt consistency and prevents overheating.
Thermoforming Efficiency: PES sheets should be heated uniformly to 200–230°C before forming to ensure proper shaping and avoid cracks.
Recycling Strategies: PES scrap material can be reprocessed with a controlled percentage of virgin resin to maintain performance while reducing costs.
Mold and Die Maintenance: Regular cleaning of molds and extrusion dies prevents contamination and ensures smooth operation, reducing production downtime.
Flow Enhancers: Using processing aids can help reduce viscosity and improve mold filling.
Reinforcement Fillers: Adding glass or carbon fibers enhances mechanical strength and thermal stability for demanding applications.
