BNX® 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.

Applications: BNX® MPM 1110 is specifically designed to beta nucleate a non-nucleated polypropylene resin when used at addition levels in the range of 0.20% to 1.0%. The major application areas for this masterbatch include thick walled extruded products such as pipe and pre-cursor sheet used to make oriented PP geogrids , as well as opaque or pigmented injection molded parts. This masterbatch can also be used for extruded sheet that is used to thermoform PP products. Beta nucleated polypropylene is not suitable for applications requiring high clarity.

Advantages:

• Can be added at the extruder hopper to produce sheet with high levels of beta crystallinity.

• Broadens the processing window for thermoforming PP, and produces thermoformed parts with more uniform material distribution and improved crush strength and rigidity, with lower sidewall density.

• In pressure and drainage pipe applications the BNX® MPM 1110 results in improved impact strength, improved long term creep resistance, and excellent chemical resistance.

• Beta nucleation improves the impact strength and ductility of injection molded or extruded polypropylene without leading to a significant decrease in modulus.

• All of the components of the masterbatch are FDA approved for food contact applications.

• The BNX® MPM 1110 will impart a slight gray color into the final part.

• The BNX® MPM 1110 can also result in more uniform shrinkage and reduced warpage in extruded and injection molded applications.
