Ecomass Technologies and compounds are continuously being developed for weighting, balancing, radiation shielding and vibration dampening products. To date, Ecomass Compounds have been used as a replacement or substitute for aluminum, steel, stainless steel, brass, bronze, copper, lead, and tungsten in a variety of applications. Ecomass® Compounds are nontoxic, high density, thermoplastic composite materials that can be formulated up to the density of lead (11.0 g/cc). These eco-friendly materials can be used as a lead replacement or lead substitute, but unlike lead, they are completely nontoxic and can meet some of the most demanding physical property requirements utilizing a variety of polymers and metal powder weighting agents. Ecomass Compounds meet the EU RoHS Directive and are completely lead-free (Pb-Free).
