|N - nucleating agentMAKROPLUS series N
|*is an organic nucleating agent masterbatch.
*The presence of the nucleating agent at the let-down ratio in the range of 3 to 5 % wt. accelerates considerably polypropylene crystallization and reduces the size of spherolites.
Nucleating effect manifests itself in:
*a considerable increase of article transparency, which is mainly observed on injection molded articles with wall thicknesses below 1 mm and also on blow molded items exposed to increased orientation. In both cases the
described effect is enhanced when highly polished molds are used.
*an improved mechanical properties, particularly of flexural modulus
*a reduced cooling time of individual processing technologies
When polypropylene is processed with the addition of this masterbatch, the processing melt temperature has to be kept above 210℃.
