Case Studies: High-Density Composite Resins

High-Density Composite Resins


Find a material that has the attributes of lead without the associated toxicity issues.


Work with material suppliers to evaluate emerging high-density composite resins that are ideal substitutes for lead.


Some of the advantages/properties of these composite resins are as follows:

  • High specific gravity: 2.0 to 11.0 (lead = 11)
  • Environmentally friendly
  • Excellent chemical resistance
  • Excellent for weighting (inertial discs, ballasts, sinkers, projectiles)
  • Radiation shielding properties equivalent to lead
  • Non toxic classification
  • Eliminate disposal issues
  • More design capability than lead
  • Can be injection molded
