Extrusion Notes
DFDA-1980 Natural can be processed on commercial thermoplastic extrusion equipment. Recommended conditions are:

Extruder
  • Extruder L/D: 20:1 to 24:1
  • Screw Suggested: Polyethylene type single flight with metering section
  • Metering Depth: Shallow rather than deep
  • Compression Ratio: 2:1 to 3:1
  • Screen Pack: 20/80/20 mesh

Extrusion Temperatures
  • Feed Zone: 395°F (202°C)
  • Center Zones: 415°F (213°C)
  • Metering Zone: 440°F (225°C)
  • Head/Die Zones: 445°F (230°C)
  • Melt Temperature: 418°F (215°C)

Tooling
  • Pressure or tube-on

Die
  • Single tapered short land die preferred for tube on applications

Draw-Down Ratio (DDR)
  • Tube-On: 1.6 to 2.0

  • Extrusion temperatures over 434°F (240°C) should be avoided to prevent premature decomposition of some components in the compound, resulting in porosity and deterioration of properties.

Compound Drying
  • Drying before extrusion in a dehumidifying hot air dryer for 24 hours at 146°F (80°C) is recommended to avoid jacket porosity and to improve the extrusion quality. Do not heat over 146°F (80°C).

Colorability
  • UNIGARD RE DFDA-1980 Natural is a colorable compound. Color masterbatch materials recommended for use in DFDA-1980 Natural should be of the type used in ethylene copolymer wire and cable products. Generally speaking, color masterbatch added at the 0.5 to 1.0% by weight gives adequate color and disperses well in the extrusion process.
Notes
1Typical properties: these are not to be construed as specifications.
2Tests based on extruded tapes 0.5 mm thickness.
3Tests based on extruded tapes 0.5 mm thickness.
The typical values of DFDA-1980 Natural shown above are based #14 AWG solid copper wire (1.63 mm dia.) with 0.030 in (0.76mm) insulation.
