Imagine an environment where the air contains some potentially explosive substance like oil fumes, sawdust, or baking flour. Then some innocent equipment creates a spark of electricity that ignites the substance flowing in the air. People can get hurt in the explosion, and the buildings can damage or even burn down.

This article discusses the processing and use of Premix’s electrically conductive plastics in the injection molding process. The electrically conductive PRE-ELEC® grades can be successfully molded with normal processing equipment. However, the processing conditions require particular attention due to their significant effect on the resistivity of the molded product.

This article covers some fundamentals, practical tips, and pitfalls related to the resistance and resistivity measurements of electrically conductive plastics. To achieve the most precise outcome, it is essential that you understand the basic measurement procedure and the key factors causing uncertainties in measurements. In this way, the probability of errors will be decreased, and analyzing the outcome of the measurement will be easier.

This post takes a look at the key element of conductive compounds – carbon black – and how it is used for creating the perfect compound mix.
