Japan Polypropylene (JPP) has launched a high melt strength polypropylene (PP) resin dubbed Waymax which consists of a reactor-produced long chain branched (LCB) material based on proprietary catalyst and polymerization technologies.
According to the supplier, existing LCB-PPs are primarily produced via "post-reactor" modification and have some drawbacks such as fish-eye and recyclability. JPP, however, has succeeded in introducing LCB structure into the polymer chain using a metallocene catalyst.
Target applications for Waymax include foamed parts and large thermoformed components where high melt strength properties come into play. Furthermore, in film applications, Waymax can be used as a processing aid to eliminate fish-eyes and produce smooth surfaces.
