The plant-derived DuPont Zytel 610 nylon resin is making its debut under the hood on DENSO Corporation’s new automotive radiator end-tank. This marks the first use of DuPont renewably sourced plastic in mechanical components exposed to the hot, chemically aggressive underhood environment.

DENSO engineering and DuPont R&D embarked on development of a new material for use in a higher performance radiator end-tank that meets auto manufacturers’ needs for sustainable solutions. 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.
DuPont has introduced a number of renewably sourced products that are made, in whole or in part, from renewable agricultural feedstocks such as corn, soybeans, castor beans, sugar cane and wheat, rather than petroleum to help industry reduce dependence on depletable petroleum-based products. Among the nine high-performance product families are: DuPont Sorona polymer, DuPont Sorona EP thermoplastic polymer, DuPont Hytrel RS thermoplastic elastomer and DuPont Zytel long chain polyamides.
