Text Box: Polyethersulfone (PES) 
 Polysulfone (PSU)

Polyethersulfone (PES) and Polysulfone (PSU) both are transparent amber colour thermoplastic, it can retain its mechanical properties well at temperature between −100C to 150C.

The materials have high dimensional stability; when its exposed to boiling water or 150C hot air or steam, under this application condition its dimension change generally falls below 0.1% .

Both PES and PSU are highly resistant to mineral acids, alkali and electrolytes and oxidizing agents, its chemical resistant PH value ranging from PH2 to PH13.

But be caution that it have poor resistant to ketones, chloride hydrocarbon and aromatic hydrocarbons substances, also It is have poor whether resistant and poor fatigue strength.
