摘要:
Process for the production of an electrically conducting carbon nanotube polymer composite material with reduced surface resistance, in which carbon nanotubes are dispersed in a polymer melt in a twin-shaft screw extruder to form a mixture, and the mixture is then extruded.
摘要:
A masterbatch comprising pigment and demoulding agent is provided. The demoulding agent is selected from the group comprising low molecular weight polyolefin oils, low molecular weight polyolefin waxes, montan waxes and aliphatic or aromatic carboxylic acid esters of fatty acids and/or fatty alcohols, wherein the pigment content of the masterbatch is from 3 to 70 wt. %, based on the total weight of the masterbatch. The masterbatch is suitable for preparation of a polymer composition having improved pigment dispersion.
