Formula: PES
Form: Disk
Material: Polyethersulfone (PES)
Commodity: Polymers
Color:
Clear Amber
The PES Disk is a precision engineered product available in 30 variations for a comprehensive choice of different diameters and thicknesses. Made from polyethersulfone, it exhibits high heat resistance and mechanical strength. PES disks are used across scientific and industrial applications, including spacers, washers, and substrates requiring dimensional stability at elevated temperatures. Their superior chemical resistance also makes them suitable for equipment exposed to aggressive environments
