The rotors of EBC are made of OE-spec grey cast iron and are backed by a 10-year warranty. The EBC rotors feature a unique geometry that promotes high air throughput. Its EBC rotors are also made of high-quality silicone, which is safer than PVC-coated wire. And, unlike many other brands, EBC does not use BPA.
Fluorine-enameled round copper wires have a low friction coefficient compared to ordinary round copper wire. This is because of the fluorine-containing chains and segments. The fluorine-containing segments in enameled wires have a radius greater than that of a hydrogen atom. As a result, the fluorine-containing chains have a lower surface free energy than hydrogen atoms, which makes them more resistant to friction.
