Wilmington, Delaware – DuPont has announced a new polymer family, Cerenol, made with corn instead of petroleum. The new polymers will be used in automotive finishes and automotive components, as well as end-use products such as running shoes, cosmetics, and spandex fibre.

The company earlier announced Sorona, a polymer which also uses renewable resources rather than petroleum. Cerenol, which is being produced at DuPont operations in Canada and the U.S., has a significantly lower environmental footprint than existing alternatives such as polytetramethylene ether glycol. According to an ISO 14000-compliant analysis, Cerenol has a 40 per cent savings in non-renewable energy and a 42 per cent reduction in greenhouse gas emissions.

The company says that the new polymer will be used in automotive primers and clear-coats from DuPont Performance Coatings, available in the first quarter of 2008; the new products provide increased chip resistance and flexibility.
