Polyimide - PI Molybdenum Disulphide Lubricated

Advantages

Lower water absorption and linear expansion, higher surface hardness and better friction compared with unmodified polyimide.

Disadvantages

Lowest flexural modulus and notched impact strength compared with the other polyimides contained within Plascams.
