Avient’s Gravi-Tech™ polymer-metal composites offer a high-performance thermoplastic-based alternative to lead and traditional metals. Using a variety of metallic fillers, these compounds have densities similar to traditional metals, while offering design and processing flexibility.


More Information

Gravi-Tech polymer-metal composites allow for greater design freedom and eliminate the costly and time-consuming finishing operations associated with traditional metal die casting and machining.



The primary features and benefits of Gravi-Tech compounds are:

  • Customized density, offering a wide range of specific gravities from 1.5 to 11 gm/cm3
  • Broad modulus range, from very flexible to very rigid
  • Corrosion resistance, withstanding oxidation for long-term use and benefit
  • Chemical resistance, withstanding fuels, oils, and other harsh chemicals


Gravi-Tech polymer-metal composites can be custom formulated for your exact end use application.
