<p>The invention is concerned with a method of preparing a conductive plastic product with the blowing method wherein the product is formed from a melt plastic mixture by means of an annular extrusion nozzle and blast gas. Conductive polymer or a plastic mixture containing conductive polymer to be doped is lead to the extrusion nozzle and blast gas is lead inside the product to be formed which blast gas contains doping agent in gas form to achieve conductivity.</p> |
