MPM® 1113 Beta Nucleant Masterbatch


MPM 1113 is a pelletized masterbatch containing a high performance proprietary beta nucleant formulation in a polypropylene homopolymer resin. This masterbatch can be added to non-nucleated and some pigmented polypropylene polymers including homopolymers, random copolymers, and impact copolymers, in order to produce high levels of beta phase crystallinity in extruded sheets, films, and pipes, as well as injection molded parts. When extruded sheets are stretched in the solid state to produce oriented films, these films will develop microvoids causing them to become white/opaque in appearance and undergo a reduction in density. In thermoforming applications beta nucleation broadens the processing window and produces final parts that have improved material distribution and higher strength and rigidity, thereby allowing the parts to be down-weighted. In polypropylene pressure pipe applications, the use of MPM 1113 leads to improved impact strength and improved long term creep performance, as well as excellent chemical resistance. MPM 1113 may also be used by resin manufacturers and compounders to produce a fully formulated beta nucleated polypropylene resin.
