Beta Nucleating Masterbatch

Beta Nucleating Masterbatch

Mayzo offers a family of beta nucleant masterbatches that are designed to produce high levels of beta phase crystallinity in thermoformed, injection molded and extruded polypropylene applications.


MPM® 1110

Introduction:                        

MPM 1110 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. This masterbatch is particularly suitable for thick extruded applications that are gray or black colored such as geogrids and certain pipe applications.

MPM 1112

Introduction:

BNX MPM 1112 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 polypropylene polymers including homopolymers, random copolymers, and impact copolymers, in order to produce high levels of beta phase crystallinity in extruded sheets, films, and 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.

MPM 1113

Introduction:

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.

MPM 2000

Introduction:

When the MPM 2000 is added to polypropylene at levels ranging from 0.25% - 2.0%, it can produce high levels of beta crystallinity in molded or extruded parts. The high beta crystal content results in dramatically higher impact strength and ductility, with very little reduction in modulus or tensile strength. If the final fabricated article is produced by post-orientation of an extruded sheet at temperatures below the melting point of the beta crystal phase, then microvoids will develop, and the density of the article will go down, and its opacity will go up. In the case of oriented films it is possible to lower the final film density by 15% when uniaxial stretching is done (MOPP), and by up to 70% when biaxial stretching (BOPP) is done. In the BOPP process it is possible to make breathable films when high levels of porosity are achieved. When the thermoforming process is used, the processing window of polypropylene is broadened dramatically, and cycle rates can be increased by 25%. Material distribution in the final part is also improved leading to potential down-weighting of thermoformed food containers by 15%. Beta nucleation can also be used to increase the tensile strength of biaxially oriented geogrids allowing for down-weighting of 15-20%. MPM 2000 can be used effectively in polypropylene resins that are already alpha-nucleated with either sodium benzoate or talc, and MPM 2000 may also work in the presence of other alpha nucleants, such as certain pigments. MPM 2000 is colorless, and has broad food contact approvals.
