Automotive fuels permeation

High temperature resistance of ETEE and other fluoropolymers ia automotive fuels and their permeation resistance have been discussed (28,29). [Pg.369]

Because TF1V Fluoroplastic is highly flexible, resistant to chemicals and automotive fuels, and has good barrier properties, it is used as a permeation barrier in various types of flexible hose in automotive applications and in the chemical process industry. Liners and tubing can be made from an electrostatic dissipative grade of TFIV, which is sometimes required for certain automotive applications.60... [Pg.85]

While the polyketone terpolymer derived from carbon monoxide, ethylene, and propylene is economical with some attractive properties, such as heat, chemical, permeation, and abrasion resistance, it suffers from low-impact strength. One cost-effective approach to overcoming this shortcoming and upgrading its performance profile for automotive applications such as wheel covers, wheel caps, fuel filter necks, fuel tanks, fuel tubes, center fascias, door handles, roof rack covers, gears, junction boxes, connectors, and seat backs, as well as electric/electronic components and durable household items involves blending with polyamides including a rubber modification (Lee et al. 2013). [Pg.1435]

With the trend to higher temperature of fuel cell operation, as is needed for both automotive and stationary applications, and the requirement for high performance, recent developments have tended towards the use not only of low-EW PFSA polymer membranes, but also in the employment of membranes of thickness only 25-30 pm (compared with the use of films of ca. 175 pm ten years ago) for their lower area specific resistance and increased water permeation rate, and both of these factors impact the membrane s mechartical strength. The difficulty lies in... [Pg.43]

Fuel and vapor tubes are typically extruded from fluoroplastics such as Tefizel EPTF inner layer and a nylon outer layer. The tubes are temperature resistant above 225°F (107°C) to fuels, fuel vapor permeation, and automotive chemicals, and the retain flexibility above 300°F (149°C). A fuel defivery tube can be constructed with Viton fluoroelas-tomer inner layer, Vamac ethylene acrylic synthetic rubber tie layer, and Kevlar fiber reinforced Teflon FEP middle layer. Flnoroelastomers have high-temperature, fuel-resistant properties that make them ideal for underhood and chassis fuel defivery components. ... [Pg.610]

Applications for epichlorohydrin are primarily automotive due to the key properties including heat, fuel, ozone, and permeation resistance coupled with very good low temperature and dynamic properties. It is also used in the roller and mechanical goods industries where the electrical properties and chemical resistance of ECO are of advantage. Basic properties of epichlorohydrin compounds given in Table 7.18 will help in determining if this elastomer is suitable for a given application. [Pg.266]

A large use of epichlorohydrin is in automotive air duct tubing because of the excellent resistance to fuel and gas permeation, fuel, heat, and low-temperature resistance of the polymer. Table 7.19 illustrates recommended compounds for Ford WSE M2D470-A4 Air Ducts. In addition, three other Hydrin C2000L compounds. [Pg.267]
