Gravi-Tech™ Lead Replacement Formulations

An eco-conscious and better alternative to lead

When Gravi-Tech™ polymer metal composites are substituted for lead, manufacturers can avoid the regulatory, disposal and employee exposure challenges associated with lead. Several grades of Gravi-Tech composites used for radiation shielding applications provide protections similar to traditional lead-based materials, yet these Gravi-Tech polymer-metal composites are 37 percent lighter. Other radiation-shielding grades are available that match the density of lead (11 gm/cm3).

HIGHLIGHTS

  • Customized density offering 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
