FUEL HOSE

Plasticizers. Plastici2ers are used to increase the flexibiHty of nylon and improve impact strength. They are most commonly used in nylon-11 and nylon-12 for such appHcations as flexible fuel hoses for automobiles. Unextracted nylon-6 is also used with the caprolactam acting as the plastici2er. Other common plastici2ers are long-chain diols and sulfonamides. [Pg.274]

The excellent properties of these fluoroelastomers come with a high price tag. Kalrez, for example, is extremely expensive ( 33—44/kg). These materials are used in automotive appHcations (seals, gaskets, fuel hose lines, engine parts, etc), where they can withstand under-hood temperatures. They are also used in equipment for oil and gas production and chemical processing. U.S. consumption in 1988 was 3100 t (76). [Pg.185]

Finally, one variation on the weight-loss method— Fuel hose testing modified GM 9061 fill and plug method —applies for fuel line aspects of fuel containment—here the sample can be from an actual hose or its liner. [Pg.640]

Because of its excellent range of properties and reliability, poly(fluoroalkoxyphosphazene) elastomers are used as seals, gaskets, and shock mounts in demanding military, aerospace, petroleum and industrial applications. In addition, applications under development for this elastomer include fuel hoses for artlc use, coated fabrics for protective clothing, sealants, coatings and medical devices. [Pg.279]

The development and optimisation is described of a new curing system to replace lead-based compounds used in epichlorohydrin elastomers currently used in automotive applications. The system is based on 2,4,6-trimercapto-1,3,5-triazine and dialkyldithiophosphate, which is shown to produce a scorch-safe curing system and which confers excellent physical and ageing properties on epichlorohydrin rubbers. Trials are conducted in formulations for multilayer fuel hoses. 9 refs. [Pg.52]

Fuel hoses such as those used to dispense methanol into vehicles have been developed that are methanol compatible. Cross-linked polyethylene has been found to be a compatible methanol fuel material. Fuel hoses designed for gasoline will harden and crack while depositing significant amounts of plasticizer into the methanol. [Pg.82]

Little is known about fuel transfer hose compatibility with ethanol. Some of the hoses used for gasoline may be adequate. Experience has demonstrated that dispensing hose made for gasoline will tolerate gasoline that has 10 volume percent ethanol [3.10]. Suppliers of fuel hose should be consulted when choosing hose that will be used for transferring ethanol. [Pg.84]

Propane is a good solvent for other hydrocarbons and the plasticizers4 used in elastomers. It is important that the right fuel hoses be used for propane. Hoses made from butyl rubber are not compatible with propane and will swell and leak. Hoses made from nitrile or neoprene should be used and are compatible with LP gas. However, even in hoses made from compatible materials, residues may result from these hoses primarily from two sources grease inside the hose from manufacturing and plasticizers present in the hose that are leached out by the propane upon first contact. (The extent of leach-out can be a function of the... [Pg.87]

They combine the high strength, oil- and gas-resistance of polyurethanes with the advantage of thermoplastic processability. They are about 15 percent of the total thermoplastic elastomer market, used in auto parts, wire and cable, medical products, and fuel hose. [Pg.655]
