Gasoline resistance

EC = Erichsen cupping, FT = film thickness, HK = Konig pendulum hardness, MEK test = resistance to butanone, and Peugeot test = premium-grade gasoline resistance. 

LX-685 [Neville]. TM for a heat-reactive resin used in the manufacture of ready-mixed aluminum paints, grease- and gasoline-resistant coatings, floor and deck enamels, and concrete curing compounds. 

Fluorine-based adhesive with low Young s modulus and high gasoline resistance to be used to bond the glass base to the case. 

In a study designed to prepare new gasoline-resistant coatings, a polymer chemist dissolves 6.053 g of poly(vinyl alcohol) in enough water to make 100.0 mL of solution. At 25°C, the osmotic pressure of this solution is 0.272 atm. What is the molar mass of the polymer sample ...

PC/ABS blends can withstand temperatures as low as minus 40°C, and the abuses associated with recreational skiing. Snowmobile throttle and brake handles are fabricated from PA/ABS alloy to take advantage of the material s gasoline resistance combined with low temperature impact strength about equal to PC. ASA is coextruded with ABS/PC blend for pleasure boat hulls. 

Nitrile rubber (acrylonitrile-butadiene copolymer) is a unique elastomer. The acrylonitrile content of the commercial elastomers ranges from 25% to 50% with 34% being a typical value. This nonhydrocarbon monomer imparts to the copolymer very good hydrocarbon oil and gasoline resistance. The oil resistance increases with increasing amounts of acrylonitrile in the copolymer. Nitrile rubber is also noted for its high strength and excellent resistance to abrasion, water, alcohols, and heat. Its drawbacks are poor dielectric properties and poor resistance to ozone. 

The most important application of nylons is as fibers, which account for nearly 90% of the world production of all nylons. Virtually all of the rest is used for plastic applications. Because of their high cost, they have not become general-purpose materials, such as polyethylene and polystyrene, which are available at about one-third the price of nylons. Nylons have nevertheless found steadily increasing application as plastics materials for specialty purposes where the combination of toughness, rigidity, abrasion resistance, reasonable heat resistance, and gasoline resistance is important.

It Is only in 1978 that the ductility of elastomer impact modified polycarbonate was associated to car bumpers, but it failed to meet the basic gasoline resistance requirements. This led to the polycarbonate-polyethylene terephthalate, non-mlsclble amorphous blends developments in 1979. Those blends showed Improved resistance to accidental contact with gasoline in the absence of stress. 

Polystyrene is miscible with poly(2,6-dimethylphenylene oxide), PPO. The commercial composition actually uses HIPS blended with PPO, again resulting in a very tough product. A blend of poly(vinylidene fluoride) with poly(methyl methacrylate) imparts both light stability and gasoline resistance, making it useful for coating automotive parts.
