Kirkland, Wash.—Prism Worldwide L.L.C. has commercially launched a thermoplastic elastomer featuring 50 percent post-consumer recycled content from end-of-life tires.
AncoraTM C-1000 TPE maintains "the look, feel and processing of a typical petrochemically derived TPE," the clean-tech materials startup said in a statement.
The Kirkland-based company said its patented process uses tire rubber as the primary feedstock in the production of polymer intermediates called PTR. The process chemically and physically converts thermoset rubber into a thermoplastic rubber product.
According to the company, the processing steps leave "essentially all the valuable polymer, linkages and carbon black intact." And most importantly, the process does not break or destroy the sulfur bonds, which according to Prism is "a major breakthrough" for the rubber industry.
