1.In order to obtain more ideal results,the processing temperature can be increased,and the maximum temperature should not exceed 210℃ .
2.The optimum extrusion temperature also ultimately depends on the compression ratio and length-diameter ratio of the user's extruder and the screw structure and other factors.
