Polyethersulfone (PESU) is a high-performance amorphous thermoplastic known for its excellent thermal stability, chemical resistance, and good mechanical properties. Thanks to its inherent sterilization resistance and strength at high temperatures, PESU is frequently used in medical, electronic, and food-related applications.Polyethersulfone (PESU) is a high-performance amorphous thermoplastic known for its excellent thermal stability, chemical resistance, and good mechanical properties.

• Medical industry: Sterilizable components such as device housings, surgical tools, sterile filters, and sample containers.
• Filtration and purification: Membranes and filter components for food, pharmaceutical, and industrial use.
• Electronics: Insulating parts, high
• voltage housings, and other thermally and electrically stable components.
• Aerospace and railway: Cabin interiors and technical parts requiring flame retardancy and thermal durability.
• Food industry: Components in coffee machines, heating vessels, and steam systems exposed to hot water and steam.
• Outstanding thermal resistance: PESU can operate continuously at around 180 °C and withstand steam sterilization (autoclaving), making it ideal for medical and laboratory applications.
• Excellent chemical resistance: The material resists a wide range of acids, bases, alcohols, and detergents, allowing usage in chemically aggressive environments.
• Good mechanical strength and rigidity: PESU maintains its strength even at elevated temperatures, without deformation or performance loss.
• Excellent hydrolytic stability: Resistant to water and moisture, PESU performs well in humid environments over time.
• Flame resistance: Naturally flame
• retardant with low thermal expansion, ensuring safety and stability under critical conditions.
• Higher cost: More expensive than standard technical thermoplastics, limiting use to specialized applications.
• Not UV
• stable without additives: Requires UV stabilizers for outdoor use.
• High processing temperature: Requires specialized equipment due to its high glass transition and viscosity.
