Masterbatch with a highly effective processing aid for polyethylene, especially PE-HD. By using the PA 0835 HD, the output can be markedly increased and the pressure build-up in the barrel decreased without increasing the screw speed. The result is an increase of the screw lifetime. PA 0835 HD prevents the build-up of deposits in the die that are caused by high pigment concentration (titanium dioxide), flame retardant, and blowing agents. Blown hollow articles from PE-HD types with different densities will get a markedly improved surface by the dosage of PA 0835 HD.Information provided by Silon |
