ECP 9603 is a proprietary TBA ECP injection moulding compound utilising multi wall carbon nanotube technology to give a permanently conductive material. Special compounding techniques at low filler loadings ensure the retention of physical properties and excellent cleanliness.

APPLICATIONS

Mouldings made from ECP 9603 exhibit excellent dimensional and chemical stability, and mouldings are clean and non-sloughing.

Typical applications include:

– Production aids for the electronics industry (e.g.,

storage boxes, bins and PCB racks.

– Static safe handling equipment tools, instruments.

Static dissipating equipment housing and ATEX applications

– Applications requiring a degree of EMI shielding

RECOMMENDED PROCESSING CONDITIONS

MACHINE

It is recommended that an in-line reciprocating screw machine be used to injection mould ECP 9603.

CYLINDER TEMPERATURE

230-270°C. The optimum cylinder temperature will depend upon the size and complexity of the moulding.

MOULD TEMPERATURE

40-60°C. The optimum mould temperature will depend upon the size and complexity of the moulding.

MOULD DESIGN

Moulds should be designed to obtain rapid filling, and multiple gates for large area mouldings are recommended with the gate positioned to avoid possible formation of weld lines.

MACHINE AND MOULD WEAR

The intensive compounding action, which takes place during the manufacture of ECP 9603, ensures encapsulation of the reinforcement in polymer. This tends to minimise wear on injection screws and moulds. There is no evidence to show that ECP 9603 causes corrosion of mould steels.

MOISTURE

ECP 9603 absorbs moisture, therefore, prior to moulding please ensure thorough drying (i.e., 90°C for 4 hours). 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 mouldings. If necessary, the material should be re-dried at 80 – 90°C in shallow trays for 2-3 hours. Other forms of drying of equivalent effect are also suitable.

USE OF REGRIND

Runners sprues and scrap mouldings 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.

HEALTH & SAFETY

CAUTION – THIS MATERIAL IS ELECTRICALLY CONDUCTIVE

As this material does not have the insulting 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 labelled.

These materials are stable at ambient and normal processing temperatures and can be processed safely in moulding and extrusion equipment at up to 300°C.
