        Lead Replacement Formulations

        Gravi-Tech™ Lead Replacement Formulations

        Adds Heft, Replaces Lead

        Using Gravi-Tech™ Lead Replacement Formulations allows manufacturers to avoid the regulatory, disposal and employee exposure challenges associated with traditional lead-based materials. Several grades of Gravi-Tech materials used for X-ray devices provide radiation shielding performance comparable to that of lead, yet these grades are 37 percent lighter. Other radiation-shielding grades are available that match the density of lead (11 gm/cm3). In addition to radiation shielding, Gravi-Tech can be used as a sustainable alternative for adding heft to a product such as spirits caps and closures, where a feeling of weight in a consumer’s hand can denote luxury and quality. With elevated heat deflection temperature and good impact strength, these formulations offer performance and versatility.
