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.

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.

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 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 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.

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.

(1). As measured on a 2% let-down of the masterbatch in polypropylene homopolymer resin on the second heat using Differential Scanning Calorimetry (DSC) (after cooling from the melt at 10oC/min., and re-heating at 10oC/min.).

Applications:

BNX MPM 1112 is specifically designed to beta nucleate a non-nucleated polypropylene resin when used at addition levels in the range of 1.0% to 2.0%. The major application areas for beta nucleated polypropylene include opaque and matte finish oriented film, breathable, microporous film, opaque thermoformed parts, and opaque or translucent injection molded parts. 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.
  • Stretching the sheet either monoaxially or biaxially produces opaque, microporous film with lowered density, high strength, and enhanced printability. Under the proper conditions the stretched sheet can exhibit high levels of vapor transmission or “breathability”.
  • Broadens the processing window for thin gauge thermoforming, and produces thermoformed containers with more uniform material distribution and improved crush strength and rigidity, with lower sidewall density. The microvoiding effect can reduce the need for TiO2 pigment in order to
    produce white containers.
  • Beta nucleation improves the impact strength and ductility of injection molded polypropylene without leading to a significant decrease in modulus.
  • All of the components of the masterbatch are FDA approved for food contact applications.
  • The MPM 1112 does not impart color into the final film or part that is made.

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.

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.

  • Broadens the processing window for thin gauge thermoforming, and produces thermoformed containers with more uniform material distribution and improved crush strength and rigidity, with lower sidewall density. This higher top load crush strength can be used to down-weight containers by 15%. The microvoiding effect can reduce the need for TiO2 pigment in order to produce white containers.
  • Faster cycle rates in both injection molded and thermoformed part production.
  • Reduces the density of oriented films, and can produce breathability in BOPP films.
  • Improves the tensile strength of biaxially oriented geogrids allowing for down-weighting of 15-20%.
