A plant-derived radiator end tank found in some 2009 Toyota Camry vehicles has been given a big green thumbs up by the Society of Plastics Engineers (SPE).

Made from DuPont Zytel 610 nylon resin, the part marks the first use of DuPont renewably- sourced plastic in mechanical components exposed to the hot, chemically aggressive underhood environment.

Developed through a joint project between DuPont and auto parts manufacturer DENSO Corporation, Zytel 610 contains 40 per cent renewable content by weight derived from the castor bean plant, and was touted as meeting industry requirements for heat resistance, durability and road salt resistance. The SPE agreed, and earlier this year selected the application to receive its 2009 “Most Innovative Use of Plastics” award in the environment category.

Production of the part for the global vehicle market began in spring 2009, and DENSO has announced its intention to use the material in a wide range of products to reduce the use of oil and of CO2 emissions in its processes.
