Engineering Thermoplastics
PES High Temp — Polyethersulfone High Temperature
PES offers a higher temperature capability and better creep resistance than PSU. It shares PSU's transparency, good mechanical properties, and chemical resistance, making it suitable for applications exposed to higher thermal stresses.
