Density Modified Formulations

Gravi-Tech™ Density Modified Formulations

Weight Without Compromise

Gravi-Tech™ polymer-metal composites are unique, high-density materials developed as effective alternatives to lead and other traditional metals. Formulated using select metallic fillers and engineered thermoplastic resins, these solutions offer densities similar to traditional metals while also providing design and processing flexibility because it can be extruded, molded, calendered or thermoformed into the final desired shape.

These customized density solutions are an excellent choice for applications where the touch, feel and look of metal can denote luxury and quality, such as spirits caps and closures, high-quality surface finishes and handles for oral and skincare products, and in more functional applications including golf clubs, cutlery, fishing tackle and other outdoor accessories where heft is necessary for optimal performance. The high-impact polypropylene (PP)-based grades offer an excellent combination of impact, density, flowability, and colorability properties.

In addition, several radiation-shielding grades are available to provide protection similar to lead-based materials at lighter weights or can match the density of lead when needed.
