CRYSTALADD® Nucleating Masterbatch resins are designed to be added to Polyethylene molding and extrusion processes by direct addition to the machine or by pre-blending with the PE resin or other masterbatch additives (i.e. colorants, slip, anti-block etc.) before processing. These masterbatch resins process at temperatures similar to other PE resins and do not require modifications to the melt or mold temperatures, pressures or other processing parameters.
