On April 27, 2026, innovative ultra-high specific gravity plastic formulas were unveiled in the materials sector, breaking the low-density limit of conventional plastics to meet demand for high-density materials in specialized industrial scenarios. Most ordinary plastics have a specific gravity of 0.9-1.3, while the newly released nylon-based high-density materials reach 3.8-11.6g/cm³, with some exceeding 10g/cm³, suitable for precision counterweight, electromagnetic shielding, radiation protection and other high-end applications. The core technology lies in efficient blending of nylon with copper powder and osmium powder, with density precisely controlled by adjusting metal powder ratios. Twin-screw extrusion works when metal powder content is below 90%; formulas above 90% require internal mixing plus single-screw extrusion to ensure molding and performance stability. Combining easy processability and corrosion resistance of plastics with high density of metals, these formulas can replace traditional metal parts, cut costs and boost efficiency. They show broad prospects in aerospace, medical electronics, automotive industry and more, driving innovation in plastic-for-metal substitution.
