Abstract
The invention relates to an injection molded part comprising a composition comprising: a. Polyarylene sulfide (PAS) in an amount of between 50 wt % and 90 wt %; b. Glass fibers in an amount of between 10 wt % and 50 wt %; wherein the composition has a sodium content of at most 3500 ppm as measured by Inductively coupled plasma atomic emission spectroscopy (ICP-AES) and wherein the composition has a iodine content of at most 100 ppm as measured by X-ray fluorescence (XRF) and wherein the weight percentage and ppm is with respect to the total weight of the composition. The invention further relates to a fuel cell comprising the injection molded part.

Injection molded part comprising a composition comprising:
- a. Polyarylene sulfide (PAS) in an amount of between 50 wt % and 90 wt %;
- b. Glass fibers in an amount of between 10 wt % and 50 wt %;
- wherein the composition has a sodium content of at most 3500 ppm as measured by Inductively coupled plasma atomic emission spectroscopy (ICP-AES) and wherein the composition has a iodine content of at most 100 ppm as measured by X-ray fluorescence (XRF) and wherein the weight percentage and ppm is with respect to the total weight of the composition.
Method for preparing a composition comprising polyarylene sulfide and glass fibers, wherein the composition has a sodium content of at most 3500 ppm as measured by Inductively coupled plasma atomic emission spectroscopy (ICP-AES) and wherein the composition has a iodine content of at most 100 ppm as measured by X-ray fluorescence (XRF) and wherein the weight percentage and ppm is with respect to the total weight of the composition, comprising the steps of heating the PAS to a temperature above its melting temperature, for example with an extruder, and subsequently adding glass fibers to obtain a mixture, after which the mixture is cooled and may be suitably pelletized.
