Rogers Corporation
A maker of high-performance engineered materials, Rogers Corporation supplies circuit materials, ceramic substrates, and cooling parts for electric vehicles, aerospace, and wireless networks, plus polyurethane and silicone foams (PORON, BISCO) used for cushioning and sealing in cars, electronics, and medical gear. It began in 1832 as the Rogers Paper Manufacturing Company, founded by Dutch immigrant Peter Rogers in a former powder mill in Manchester, Connecticut, before evolving into advanced materials. During the Great Depression it partnered with plastics pioneer Leo Baekeland to develop phenolic molding compounds, a step that helped it outgrow its papermaking roots.
