Applications & Uses

- Plastics & Elastomers Processing Methods
- Applications
ECP 245 is recommended for use in applications that require the usual advantages normally associated with Nylon 6 where magnetic detection requirements also exist, for example:-
- Bearings and machine parts where friction characteristics predominate, such as gear, slide, cams and bearings
- Parts that require good physical properties for example cable ties, brush bristles
- Parts that need to exhibit good chemical resistance allied to magnetic properties

Technical Details & Test Data
- Recommended Processing Conditions
- Machine - It is recommended that an in-line reciprocating screw machine be used to injection mold ECP 245, but it is possible to process this material on plunger injection molding machines.
- Extrusion - Normal extrusion equipment should be used.
- Cylinder Temperature - 260 - 280 °C depending on the size and complexity of the molding.
- Mold Temperature - 60 - 80 °C higher mold temperatures generally improve physical properties but the optimum is based on the size and complexity of the moldings.
- Mold Design - Nylon 6 compounds have a sharp melting point and low melt viscosity therefore mold surfaces should mate well to avoid excessive flash. Runners and gates should be as large as practicable to avoid denigration of physical and electrical properties. Sprues and runners should be as short as possible to avoid premature material freezing.
- Moisture - ECP 245 readily absorbs moisture and should be dried to a moisture content of 0.1%. ECP 245 is normally supplied dried, but if for some reason the material has picked up moisture then the material should be dried for a minimum of 4 hours at 100°C in a re-circulatory oven in shallow trays or by any other suitable drying method. The wet compound manifests itself as spitting on the molding.
- Use of Regrind - Runners, sprues and scrap moldings can be reground and blended with virgin material. 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.
