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

In Injection Molded or extruded products the use of beta nucleation leads higher impact strength and reduced warpage, with very little loss in flexural modulus.

In Thermoformed applications the following benefits can be achieved:

• Reduction in Part Weight

  –Typically 10-15% weight reduction

• Improved Productivity

  –Up to 20% reduction in cycle time

• Improved Dimensional Stability at High Use Temperatures
• Improved Material Distribution Leading to Higher Crush Strength and Rigidity

  –Thicker and more uniform sidewalls

• Broader Processing Window

  –Less sagging and lower processing temperatures

• Natural White/Opaque Appearance

  –30-50% Less TiO2 is needed to make a white container.

In Geogrid products the following benefits can be achieved:

• More uniform drawing (smaller node regions & wider, thicker strands)
• Higher Tensile Strength
• Higher Torsional Rigidity
• Significant raw material savings due to down-weighting potential (up to 25% lighter weight)
• Higher line speeds (productivity improvement)
    –up to 50% increase in through-put rates observed
