BNX MPM 1110 Beta Nucleant Masterbatch


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 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.


  • 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 MPM 1110 results in improved
    impact strength, improved long term creep resistance, and excellent chemical
  • Beta nucleation improves the impact strength and ductility of injection molded
    or extruded polypropylene without leading to a significant decrease in
  • All of the components of the masterbatch are FDA approved for food contact
  • The MPM 1110 will impart a slight gray color into the final part.
  • The MPM 1110 can also result in more uniform shrinkage and reduced
    warpage in extruded and injection molded applications.

Loading Instructions:

The loading data and results are based on laboratory work (and field-testing) under controlled conditions and do not necessarily indicate the result that the buyer or user will attain. For this reason, we strongly recommend testing of your own system under the actual conditions of processing and end-use prior to full scale testing. The generally recommended loading concentration range is between 0.20% and 1.0% depending on the base polypropylene resin, the processing conditions used, and the presence of any other additives that may have slight nucleating characteristics such as certain pigments. When added to polypropylene resins that already contain certain weak nucleating additives, the higher end of the addition range should be used.

FDA Status:

The components of this product fall under one or more of the following categories for use in contact with food:

  • Colorants listed in 21 CFR 178.3297 “Colorants for Polymers”.
  • Components that are exempt from regulation under 21 CFR 170.39 “Threshold of Regulation for Substances Used in Food Contact Articles”.
  • Polymers and/or additives listed in the appropriate parts of 21 CFR (174, 175, 176, 177, 178, 181, 184 and 186).
  • Substances that, based on legal opinion, supplier certification, and/or extraction results from food-simulating solvents, are not food additives and are acceptable for this application in full compliance with the Federal Food, Drug, and Cosmetic Act and all applicable food additive regulations.
  • Substances that are GRAS (Generally Recognized as Safe) for direct addition to food or for use in contact with food.
  • Substances that are “Prior Sanctioned” for use in this application.


In order to maximize the beta crystal content of extruded sheet, the cast roll should be heated to at least 80oC, and should preferably be in the range of 90 – 130 degrees Celsius. In thick sheet or thick walled applications (thickness > 2mm) lower cooling temperatures can be used successfully.

It is also important that no other additives which nucleate the alpha crystalline form, such as clarifying agents, be present in the beta nucleated polypropylene material. Mayzo will provide technical assistance to customers in order to help them optimize the processing conditions for their particular application.

Toxicity & Safety: 

This material is not intended for use in products for which prolonged contact with mucous membranes or abraded skin, or implantation within the human body is specially intended, unless the finished product has been tested in accordance with the Food and Drug Administration and/or other applicable safety testing requirements. Because of wide range of such potential uses, Mayzo, Inc. is not able to recommend this material as a safe and effective for such uses and assumes no liability for any such uses.
