PPSU Rod

PPSU Rod

PPSU is kind of amorphous, high-performance thermoplastic plastic. Compared with PSU and PEI, PPSU has better impact resistance and chemical resistance.
Through high pressure steam sterilizing test, PPSU is proved to have the best hydrolysis resistant better than other amorphous plastic. In fact, PPSU can stand million times of high pressure steam sterilizing, which makes PPSU a very good choice for medical application.
