Abstract:
1. An antistatic or electrically conductive, thermoset polyurethane obtained by reacting: A) an organic polyisocyanate; B) a compound comprising NCO-reactive groups; and C) optionally a catalyst, a blowing agent, an auxiliary, an additive, or mixtures thereof; and wherein, the polyurethane comprises a carbon nanotube present in an amount of from 0.1 to 15% by weight based on the total weight of the polyurethane, and wherein the carbon nanotube has a proportion of from 30 to 90% by weight having a particle size of less than 40 μm; and a proportion of from 10 to 70% by weight having a particle size of from 40 to 1000 μm, wherein the carbon nanotubes having a particle size of from 40 to 1000 μm comprises more than 90% of particles having a diameter of from 100 to 200 μm.
