Examples of routes for fireproofing

According to the conductivity level, the main additives used are  

Non-black antistatics allow surface resistivities roughly in the range of 10 to 10 ohms per square to be obtained but their action generally depends on the relative humidity. However, new generations are being marketed without this drawback and are efficient at a relative humidity as low as 15%. Some are offered in masterbatches based on polyolefins, polystyrenes, polyesters, acrylics, ABS, polyacetals. .. 

There are specific grades and masterbatches of carbon blacks especially marketed as additives for conductive plastics. It should be noted that the carbon blacks modify other properties of the polymer, especially its colour. 

Specific grades of carbon and steel fibres are especially marketed as additives for conductive plastics allowing resistivities of roughly 10 ohm.cm to be obtained. The other properties of the final material - colour, modulus, impact strength. .. are modified. Carbon fibres have a large reinforcing effect.
