Influence of the carbon black type<br />
on the resistivity:<br />
Compounding: ZSK57 twin screw extruder.<br />
Processing: injection moulding.<br />
Influence of the carbon black type on mechanical and<br />
rheological per<strong>for</strong>mances:<br />
Compounding: ZSK57 twin screw extruder.<br />
Processing: injection moulding.<br />
Although the concentration <strong>for</strong> percolation is double the level with<br />
ENSACO ® 250 G, most mechanical properties are still better.<br />
Tensile Strength <strong>for</strong> both carbon blacks is almost at the same level.<br />
