Technical Details & Test Data
- Processing
Extruder - An extruder with an L/D ratio (length/diameter) between 15 and 24 and a screw with a compression ratio 1.2:1 are recommended.
Extruder Temperature Conditions - It is important that the melt temperature is not allowed to increase above 160oC. As a guide the following temperature profile is recommended:Zone #1 Zone #2 Zone #3 Zone #4 Head Die Celsius 130°C 140°C 145°C 150°C 160°C 160°C Fahrenheit 266°F 284°F 293°F 302°F 329°F 329°F This profile will vary slightly depending on extruder type, head design and output. Initial purging of the extruder should be performed without the addition of catalyst masterbatch to reduce risks of pre-curing.
