Technical Details & Test Data

Recommended Processing Conditions
  • Machine - It is recommended that an in line reciprocating screw machine be used to injection mold ECP 225 but it is possible to process this material on plunger injection molding machines.
  • Extrusion - Normal extrusion equipment should be used.
  • Processing - Processing conditions will vary depending upon the machinery employed but good quality product is achieved using moderate blow ratios with extruder temperatures from 120 - 160 degrees centigrade and die temperatures between 160 - 180 degrees centigrade.
  • Moisture - It is recommended that ECP 225 be dried prior to extrusion.  Excess moisture may show as an inferior surface finish.  Typically 2/4 hours at 80°C is adequate.  Store in a warm dry place to avoid moisture.
  • Use of Re-grind - Runners sprues and scrap moldings can be reground and blended with virgin materials.  Regrind additions should not exceed 10% by weight of the virgin material otherwise some reduction in properties may be experienced.

Safety & Health

Safety and Health

Do not use a magnetic separator in the molding machine and hopper, the grains will separate and stick to the magnet.
