How much color variation can I expect to encounter with natural color Ryton PPS compounds?
The color of Ryton PPS compounds depends on several factors, including types of fillers and reinforcements, the amounts of these fillers and reinforcements, and the heat history the material sees during processing. Purely glass-reinforced compounds (like Ryton R-4) are a fairly dark brown color, while glass-and-mineral-filled compounds (like RytonR-7) are a lighter brown to dark tan color. These colors can vary somewhat depending on how the compounds are processed. More heat history typically produces a darker molding; however, annealing amorphous (cold molded) parts will result in a lightening of color. Even though there is no color specification for the natural compounds, they are fairly consistent in color, with only slight variations due to the above factors. Variation in color is no indication of diminished mechanical properties.
