"Prius α" uses DuPont bio-based resin

Toyota's "Prius α" internal components use DuPont bio-based resin "Sorona EP"

Dupont announced that Toyota used the "Sorona EP", a bio-based resin jointly developed with Toyota, Kojima Stamping Industry and Toyohwa Chemicals, in the air conditioning outlet of the "Prius α." This part, as the dashboard component that dominates the interior style, requires both high creativity and heat resistance, strength and dimensional stability required to control the strength and direction of the wind.

"Sorona EP" is a bio-based resin derived from plants in a weight ratio of 20 to 37%. The raw material is a polymer of a PTT (polytrimethylene terephthalate) resin "Sorona" obtained by copolymerizing 1,3-propanediol and phthalic acid produced by fermentation of sugars in plants by DuPont Biotechnology. Compared with the original PBT (polybutylene terephthalate) resin, not only can reduce CO2 emissions, but also has almost the same heat resistance and strength as PBT resin, and low flexibility and appearance are also very Excellent, so it is expected to reduce the manufacturing process.
