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 rise above 190°C.
As a guide the following temperature profile is recommended:Zone #1 Zone #1 Zone #1 Zone #1 Head Die Celsius 130°C 150°C 170°C 180°C 190°C 190°C Fahrenheit 266°F 302°F 338°F 356°F 374°F 374°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.
