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.
