The plant-derived resin radiator end tank, which can be found in some 2009 Toyota Camrys, has just earned the Most Innovative Use of Plastics award in the Environment Category from the Society of Plastics Engineers (SPE) Automotive Division for Toyota and partners DENSO and DuPont Automotive. "We are proud to receive this prestigious award, which recognizes our collaborative efforts in developing an environmentally friendly component that can withstand the extreme environment in the engine compartment," said Sojiro Tsuchiya, senior managing director responsible for overall production affairs. "DENSO aims to expand the use of the radiator tank to more vehicles and incorporate plant-derived resin into a wide range of products."
Not only is the resin made from environmentally friendly materials, but the new radiator tank releases less carbon dioxide (CO2) emissions into the atmosphere during its life cycle than the conventional product. This can partially be attributed to the fact that Zytel® RS is extracted from plants, which absorb CO2 through the photosynthesis process. Also, because less petroleum is used to produce the end tank, the new product also helps conserve oil.
Since engine compartment components - like the radiator tank - need to be extremely durable and heat resistant, it was previously difficult to develop a resin with a high percentage of plant-derived ingredients.
