Technical Details & Test Data
- Recommended Processing Conditions
Machine : It is recommended that an in-line reciprocating screw machine be used to injection mold ECP 2747
Cylinder Temperature : 240-250°C. The optimum cylinder temperature will depend upon the size and complexity of the molding.
Mold Temperature : 25-80°C. The optimum cylinder temperature will depend upon the size and complexity of the molding.
Mold Design : Molds should be designed to obtain rapid filling. Multiple gates for large area moldings are recommended with the gate positioned to avoid possible formation of weld lines.
Machine and Mold Wear : There is no evidence of any wear associated with this compound.
Moisture : ECP 2747 can absorb moisture therefore prior to molding please ensure thorough drying. Materials should be re-dried if all the material is not used within 2-3 hours of opening the bag. Excess moisture may show as splash marks on the surface of the finished moldings. If necessary the material should be re-dried. Typical drying conditions are 2-3 hours at 95°C.
Use of Regrind : 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
Caution - This material is electrically static dissipative
As this material does not have the insulating properties normally associated with polymers, due safety precautions must be taken in use and it is recommended that all products made from this material be suitably labeled.
