ABSTRACT
This chapter sounds silly to anyone who works with materials or has knowledge of them or designs parts and devices in just about any industry. Uses of fluoropolymers in internal combustion automobiles rely on several basic properties including high temperatures and chemical resistance, low-friction, and durability. Fluoropolymers have routinely been used in automobile fuel systems, power trains, brake systems, electrical systems, heat, ventilation, and air conditioning systems, chassis, and interiors. The ever-rising under-hood temperatures and requirements to prevent atmospheric emissions of fuel and other fluids can be accomplished quite efficiently using fluoropolymers. PTFE is used to insulate wires connected to oxygen sensors which are mounted in vehicle exhaust manifolds. PTFE is quite suitable for this hot environment by providing reliable dielectric protection for the wiring to ensure adequate control exhaust emissions.
