DuPont's plant-derived Zytel® 610 nylon resin has been applied for the first time on a new automotive radiator end tank from DENSO Corp. which illustrates the benefits of close collaboration throughout the value chain. This use marks the first use of DuPont renewably-sourced plastic in mechanical components exposed to the hot, chemically aggressive underhood environment. The new material, developed jointly by DENSO and DuPont in a proprietary process, contains 40% renewable content by weight derived from the castor bean plant, and meets requirements for exceptional heat resistance, durability and road salt resistance - attributes DENSO says were difficult to deliver with many resins containing a high percentage of plant-derived ingredients.
Production of the part for the global vehicle market begins this spring and DENSO has announced intentions to use the material in a wide range of products to reduce use of limited oil resources and reduce CO2 emissions in its processes to help prevent global warming. "The strategy of collaborating throughout the value chain is critical when cost effectively bringing high-value solutions to the market," said Chris Murphy, global accounts director - DuPont Engineering Polymers. Shared goals, objectives and clear timelines were essential elements in this program, according to Masatoshi Ikeda, global account manager of Denso Group, DuPont Engineering Polymers.
