Using ethanol, biodiesel and other biofuels are becoming commonplace as we seek alternatives to nonrenewable oil resources and try to reduce harmful emissions. According to the U.S. Department of Energy, roughly 97% of gasoline in the U.S. contains some ethanol. The problem is that these biofuels and additives are extremely harsh on vehicle fuel systems and components. Furthermore, to avoid damaging fuel system components, manufacturers are using hoses and other parts made with new fluoropolymers. These compounds are able to significantly improve chemical resistance.
Fluoropolymers for automotive components include:
Adhesive ETFE: These resins enable automotive components such as liquid and vapor fuel lines, compressor hoses, fuel tanks and filler necks exhibit outstanding performance in any construction.
High-Temperature ETFE: An ideal material for industrial and automotive wire and cable insulation and under-floor heating cables.
Low-Melting Adhesive ETFE: A cost-effective solution in applications such as hot water hoses, rubber hose mandrels, interlayer insulation film for electronic substrates and multi-layer tubes that convey harsh materials.
Filled PTFE Compounds: Ideal for applications that need to withstand ongoing heat and pressure. For example, fuel tanks, connectors, oxygen sensors and seals for fuel systems.
Because these fluoropolymers exhibit superior performance properties, it’s no wonder why vehicle manufacturers today rely on them throughout automotive systems. From engines and brakes to fuel components and electronics, these compounds provide resistance against corrosion, heat and chemicals.
