Gravi-Tech™ Density Modified Formulations

Customized densities to meet your application needs

Gravi-Tech™ polymer-metal composites are unique, high-density materials developed as thermoplastic-based alternatives to lead and other traditional metals. These materials have been formulated using select metallic fillers and engineering thermoplastic resins to have densities similar to traditional metals, while also providing the design flexibility and processing ease of conventional thermoplastics. 

HIGHLIGHTS

  • Customized density with a wide range of specific gravities (1.5 - 11 gm/cm3)
  • Broad modulus range, from very flexible to very rigid grades
  • Corrosion resistance that withstands oxidization for long-term use and benefit
  • Chemical resistance that withstands fuels, oils and other harsh chemicals

Additional features:

  • Design flexibility and processing ease
  • Good impact strength
  • Elevated heat deflection temperature
