| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| preparation | The PPS Resin was dried under vacuum at 120 °c for 12 h, and then in accordance with 0. 5%, 1. 0%, 3. 0% and 5. 0 %(mass fraction, the same below) mixing ratio of the antioxidant GA 80 and PPS Resin are mixed evenly, and then the micro twin-screw extruder is used for melt blending and extrusion, the partition temperature of the screw extruder was 280, 285, 290 ℃, the blending time was 3 min, and the screw speed was 25 r/min, where x is the content of the antioxidant GA Δ80. |
| effect | The antioxidant GA Δ80 has good compatibility with PPS, and can be uniformly dispersed in the PPS matrix, when the content of GA +80 is more than or equal to 3. 0%, GA 80 will produce partial agglomeration. |
