SABIC deployed recycled thermoplastics for GENBETA’s injection-molded wheel fins, which are designed to optimize airflow and reduce drag. “As an additional benefit, the fins can increase the car’s overall efficiency and aid in cooling the brakes to improve stopping power,” SABIC notes.
Apparently, the plastic used in fusion deposition modeling is not part of SABIC’s sustainable plastics portfolio, though the company could eventually take it in that direction.If you caught that thing about thermoplastics in the GENBETA electric car, that’s of note from a recycling perspective. Thermoset plastics are favored for durability and heat resistance, but they are much more difficult to recycle than thermoplastics. Instead of melting into a docile puddle when heated, they tend to catch fire.a new method for producing thermoset plastics
. As of 2020, they were also looking into another process, called mechanochemical ball-milling, that renders thermoset plastics into a powder resin.SABIC currently produces some of its sustainable plastics with mechanical processes, which involve washing, shredding, and grinding, among other activities. However, the company has made it known that its long-term plans focus on feedstock recycling. That involves pyrolysis, the application of high heat in an oxygen-free environment.
