The synthesis of ethylene diformate can be performed through several methods, with the most common being the direct esterification of ethylene glycol with formic acid. In this process, the reactants are typically heated in the presence of a catalyst to promote the formation of the ester bond while releasing water as a byproduct. Alternatively, transesterification reactions involving other esters and ethylene glycol can also yield ethylene diformate. These approaches can be optimized by controlling temperature, pressure, and reaction time to improve yield and purity.

Anti-fog plastics are engineered materials that have been treated or coated to reduce the occurrence of condensation buildup. This condensation leads to fogging, which can obstruct vision. Anti-fog technologies work primarily through two methods hydrophilic and hydrophobic treatments. Hydrophilic coatings spread moisture evenly across the surface, preventing bead formation and allowing for improved clarity. In contrast, hydrophobic treatments repel water, causing it to bead up and roll off the surface instead of clinging to it.

The brake drum is a cylindrical component that houses the braking mechanism. It is typically made of cast iron or aluminum, designed to withstand the high temperatures generated during braking. Brake shoes, on the other hand, are curved pieces of friction material that press against the inner surface of the brake drum to create the necessary friction to slow down or stop the vehicle.
