DuPont has announced its next polymer family made with renewable resources: Cerenol. This patented new product line joins DuPont Sorona as the newest polymer family made with corn instead of petroleum.
Cerenol is a family of renewably sourced, high-performance polyols (polyetherdiols). The liquid polyol is made using Bio-PDO from the DuPont Tate & Lyle Bio Products joint venture in Loudon, Tenn. Cerenol is the result of polymerizing Bio-PDO with itself. (Earlier post.)
Compared to existing alternatives such as polytetramethylene ether glycol (PTMEG), DuPont Cerenol has a significantly lower environmental footprint as determined by an ISO 14000-compliant Life Cycle Analysis, because from cradle to gate it has a 40% savings in non-renewable energy and 42% reduction in greenhouse gas emissions. Cerenol is being produced at DuPont operations in the United States and Canada.
Cerenol will be the building block for two other renewably sourced products from DuPont. First, for new automotive primers and clearcoats from DuPont Performance Coatings that will be available in the first quarter of 2008, Cerenol provides increased chip resistance and flexibility. Second, grades of DuPont Hytrel thermoplastic elastomers made with Cerenol will be available in late 2007 and will offer performance comparable to conventional grades.
Cerenol can replace petroleum-based ingredients or finished products without compromising functionality. It offers value-added properties and can increase process efficiencies for a broad range of products in diverse markets including personal care, functional fluids and high-performance elastomers.
