At constant exposure to high temperatures (e.g. 180 C), many grades of PPS discolor badly. Does anobody know of PPS grades that have superior color stability?
 
Many times discoloration of a polymer is due to the antioxidants and other additives and not the polymer itself.

Can you try masking the color change e.g. using carbon black or TiO2 as pigments?
