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 160°C. As a guide the following temperature profile is recommended:

  Zone #1 Zone #1 Zone #1 Zone #1 Head Die
Celsius 130°C 140°C 145°C 150°C 160°C 160°C
Fahrenheit 266°F 284°F 293°F 302°F 320°F 320°F

This profile will vary slightly depending on extruder type, head design and output

Screw Water Temperature - Not mandatory, if present we recommend 40°-60°C

Recommended Screen Pack - Spacer ring or breaker plate only

Head & Tool Design: The head and tools should be so designed as to allow streamlined flow of material. To obtain the optimum in physical properties in the case of tubing tools, a maximum draw down ratio of 1.5:1 is recommended to avoid internal stresses.

Color Masterbatches: EVA, preferable, and PE based color masterbatches including black, up to a maximum of 1%, have no detrimental effect on the properties. It is recommended that all masterbatches should be thoroughly dried before use for 8 hours at 60°C or 4 hours at 80°C in a de-humidifying drier.
