Beta Nucleating Masterbatch

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

In Oriented Film applications the following benefits can be achieved:

• Reduced Film Density

  –Higher film yield per lb. of resin

• Can be made breathable at very low densities
• Can be used for battery separator membranes and synthetic paper
• Improved Printability
• Uniform White/opaque appearance without fillers or pigments

• Dramatic improvement in impact strength.
• Lower yield stress leading to better ductility and higher break elongations.
• Very small loss in flexural modulus leading to better stiffness/impact balance.
• Reduced warpage in certain applications such as caps and closures.
• A new experimental beta nucleant masterbatch (MPM 1114) that can be used in certain alpha nucleated PP grades to achieve the above-mentioned benefits of beta nucleation.
