Plastics for the Long Haul: Polymer Selection Helps Automotive Fuel-system Components Survive for the Life of the Vehicle.

Publisher: Celanese
Overviewing how the use of right polymers could retain fuel systems' strength and dimension, this paper lists some plastics like polyamides, POM, POM-H, HDPE, PBT, and PPS which are used in fuel-system components. It explains how environmental and other regulations affect the use of plastics, and highlights the importance of plastics in designing fuel cells for reducing environmental constraints. A study conducted by Ticona on the interaction of plastics and fuels, featuring nine fuels and three plastics at 65C fuel-tank, and five fuels and four plastics at 121C engine-compartment temperatures is briefly detailed in it. Tables illustrating typical plastics applications in auto fuel systems are also included. The paper concludes that alterations in fuel systems could require the polymers at higher levels and must also adapt with any fuel under any set of circumstances.
