Engine cover
Castor oil protects the engine
Components in the engine compartment of a car must be able to withstand extreme heat loads of over 200 degrees Celsius. Daimler uses biopolyamide engine covers for the Mercedes A-Class. While conventional plastic is produced from crude oil, the cover consists largely of castor oil. The oil is extracted from the seeds of the castor oil plant Ricinus communis, which belongs to the spurge family.
