What is the recommended moisture content level for Ryton PPS compounds?
Although we have no recommended moisture level, Ryton PPS compounds will be more readily processed if dried thoroughly. Less than 0.02% moisture should be sufficient, and following our standard drying recommendations (300-350F, 149-177C for 2 to 3 hours) should accomplish this. Longer drying times are not harmful, but temperatures above 400 F (204C) may reduce melt flow. The resin itself is not hygroscopic, but some mineral fillers may be, so drying is particularly important for mineral filled compounds.
