Nucleating agents are chemical substances which after incorporation in plastics form nuclei for the growth of crystals in the polymer melt. Nucleating agents promote the crystallization of semi-crystalline polymers. These additives function by presenting a heterogeneous surface to the polymer melt, making the crystallization process more thermodynamically favorable. As a result of this effect, the temperature at which the polymer begins to crystallize from the melt is increased, as are the rate of nucleation and overall rate of crystallization. Nucleating agents also promote the formation of smaller and more numerous spherulites.We provide with NUCLEATING MASTERBATCH which uses polypropylene as the carrier material. Polypropylene is recognized as a relatively easy material to nucleate. This is because the rate of crystallization is low enough to allow the nucleating agent to have a direct impact on the nucleation density.
