Technical Details & Test Data
- Recommended Processing Conditions
- Machine - It is recommended that an in line reciprocating screw machine be used to injection mold ECP 41899.
- Cylinder Temperature - 180 - 220 °C. The optimum cylinder temperature will depend upon the size and complexity of the molding.
- Mold Temperature - 25 - 50 °C. The optimum mold 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 evicence of any wear associated with this compound.
- Moisture - ECP 41899 can absorbs 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 these finished moldings. If necessary the material should be re-dried.
- 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
Caution - This material is electrically conductive
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 are suitably labeled. These materials are stable at ambient and normal processing temperatures and can be processed safely in molding and extrusion equipment.
Acrylic based materials are stable at ambient and normal processing temperatures and can be processed safely in molding and extrusion equipment up to 2350C.
