Gravi-Tech™ Density-Modified Formulations High-Performance Alternative to Lead and Other Traditional Metals PRODUCT DESCRIPTION Gravi-Tech™ polymer-metal composites offer a high-performance thermoplastic-based alternative to lead and other traditional dense metals. VALUE SOLUTION Improve safety and reduce costs with Gravi-Tech formulations 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.

Too often, however, the laser-sensitive pigments and colors incorporated into the polymers selected for these applications cannot keep pace with the higher machine speeds, leading to poor legibility and contrast.  In practice, a laser beam activates a laser-sensitive additive embedded in the polymer. We encourage manufacturers to collaborate with our laser marking experts to ensure that marking and contrast can be optimized for each color and polymer.”
