Is it possible to pigment Ryton PPS to make it a different color?
The dark brown color of the 40% glass fiber reinforced grades is not amenable to pigmenting any color other than black. Some of the lighter color glass and mineral filled grades may be pigmented a variety of colors using commercially available color concentrates blended in at the injection molding machine. However, it is important to understand that the parts will not be color stable if exposed to elevated temperatures, UV light, or outdoor conditions. So, pigmenting Ryton PPS may be useful in some situations for part identification, but pigmenting Ryton PPS is not recommended for cosmetic or decorative purposes. Although Ryton R-7-120NA has a UL “All Color” listing when used in conjunction with certain color concentrates, the addition of pigments may void the UL certification of other Ryton PPS compounds. In general, if color stability and consistency is required, black color Ryton PPS compounds should be used. Natural color Xtel PPS-based alloys (Xtel XK2040and Xtel XK2240) may also
