PES — Polyethersulfone Resin

PES — Polyethersulfone Resin

PES (Polyethersulfone) is a high-performance amorphous thermoplastic with outstanding thermal stability, excellent hydrolytic resistance, and inherent flame retardancy. It maintains its properties over a wide temperature range and is suitable for repeated sterilization.

Key Properties

• High continuous use temperature (up to 180°C)
• Excellent hydrolytic stability and steam resistance
• Inherent flame retardancy (UL94 V-0)
• Good optical clarity and dimensional stability

Typical Applications

• Medical sterilization equipment
• Membrane filtration for water and food processing
• Aerospace interior components
• High-temperature electrical connectors
