Additional Information

Processing Techniques:

It is recommended to use a low smoke zero halogen special screw, with a length to diameter ratio of L/D=20-25 and a compression ratio of 1.2-1.8. Because the actual temperature of the melt is related to the length diameter ratio, compression ratio and screw structure of the extruder, the appropriate extrusion temperature should be selected according to the specific situation of the extruder.
The recommended setting temperatures for each zone of the 70 extruder are as follows:
