There are two well established, similar methods for measurement of conductive plastics, here is a short comparison of them. I’ll add pictures of my solutions in due time – if interested, ask for quotation via contact form
- Current electrodes are on both sides of the sample, aligned and connected with a jumper wiring.
- Load between the current electrodes is varied according to the sample width, which is defined as 1 to 15 cm. The applied force is 300 N/m.
- Pointy voltage electrodes are on the bottom side of the sample. Applied force is 60 N/m.
- More streamlined measurement process.
- Sample is fixed to outer electrodes with more leeway in design, not necessarily from both sides.
- Current electrode load is not specified, while the voltage sensing system mass is defined to exert roughly a force of 0,6 N on the sample across the span of 10 ± 0,2 mm.
- More complicated sampling process.

In case none of these are what you’re looking for, get in touch via contact form and we’ll see if we’ve got something ready, in case not, then we’ll provide you a feasibility check including estimates for cost and lead time.
