MPM® 1112

MPM® 1112 by Mayzo is a pelletized masterbatch with a high performance proprietary beta nucleant formulation in a polypropylene homopolymer resin. It produces high level beta phase crystallinity in films, extruded sheets, and injection molded parts when added in non-nucleated polypropylene polymers including homopolymers, random copolymers, and impact copolymers. It broadens the processing window for thin gauge thermoforming, and produces thermoformed containers with more uniform material distribution and improved crush strength, rigidity, with lower sidewall density. When extruded sheets are stretched in the solid state to produce oriented films, these films become micro voided, appear white and opaque, and shows reduction in density. Application areas for beta nucleated polypropylene include opaque/matte finish-oriented film, breathable, microporous film, opaque or translucent injection molded parts and opaque thermoformed parts. Recommended addition level is 1.0% to 2.0%. MPM® 1112 is approved by FDA.
