Plasticizers hydrocarbon process oils

Several types of plasticizers are used in ABS. These include hydrocarbon processing oil, phosphate esters (e.g., triphenyl phosphate, resorcinol bis(diphenyl phosphate), or oligomeric phosphate), long chain fatly acid esters, " and aromatic sttlforramide. ... [Pg.273]

This group of high volume nonpolar elastomers is typically plasticized with soybean and rapeseed oil factices and the full range of hydrocarbon process oils. Only when a special lubricating effect is wanted is a synthetic plasticizer used. To illustrate, the following two examples (a) 10 phr DOA added to an EPDM Arctic CB radio coil cord where it acted as an extreme low temp (LT) flexibilizer (b) a typical LT glycol ester (TEG-2EH) used at 8 phr in BR to achieve both processing and LT enhancements. In both examples, the incompatible plasticizer acted as a lubricant. [Pg.406]

Solvent wiping. Rubbers tend to swell by application of solvents and the mechanical interlocking of the adhesive is favored. Although chlorinated hydrocarbon solvents are the most effective, they are toxic and cannot be used toluene and ketones are currently the most common solvents. The treatment with solvents is effective in the removal of processing oils and plasticizers in vulcanized mbbers, but zinc stearate is not completely removed and antiozonant wax gradually migrates to the mbber/polyurethane adhesive interface. Table 27.1 shows the moderate increase in adhesion produced in SBR by MEK wiping. [Pg.762]

Mechanical properties (stiffness, impact, and shock resistance), electrical properties, clarity, ease of processing, sealing properties, dimensional stability, resistance to hydrocarbons and other organic liquids, resistance to plasticizers, greases, and oils are the characteristic properties desired. In its mechanical properties it approaches polycarbonate most closely. However, since polycarbonate is cheaper than Trogamid T, Trogamid T will be preferred only where polycarbonate cannot be used. [Pg.644]

Rubbers are plasticized with petroleum oils, before vulcanization, to improve processability and adhesion of rubber layers to each other and to reduce the cost and increase the softness of the final product. Large quantities of these oil-extended rubbers are used in tire compounds and related products. The oil content is frequently about 50 wt% of the styrene-butadiene rubber. The chemical composition of the extender oil is important. Saturated hydrocarbons have limited compatibility with most rubbers and may sweat-out. Aromatic oils are more compatible and unsaturated straight chain and cyclic compounds are intermediate in solvent power. [Pg.462]

The main use of mineral oil in medicine has been as a laxative (an alimentary tract lubricant) and in various pharmaceutical preparations such as ointments, and, as such use continues, this quality of oil is finding increasing utilization as a lubricant for food processing machinery and in plastics manufacture. Laxative oils should be free of odor and taste and also be free of hydrocarbons that may react during storage and produce unwanted by-products. These properties are attained by the removal of oxygen-. [Pg.256]

The lifeblood of modern society is found in petroleum products. Cars, planes, trains, ships, and farm equipment all require petroleum products to operate. Approximately 85% of all hydrocarbons manufactured are converted into gasoline. Jet fuel, diesel, heating oils, and liquefied petroleum. The remaining 15% provides the foundation (feedstock) for fertilizers, pesticides, pharmaceuticals, solvents, plastics, and many other products. It is difficult to look around our world and not see the results of modern petroleum manufacturing. Before 1800, though, few people recognized the value or potential of hydrocarbon processing. [Pg.3]

Commercial cmde lecithin is a brown to light yeUow fatty substance with a Hquid to plastic consistency. Its density is 0.97 g/mL (Uquid) and 0.5 g/mL (granule). The color is dependent on its origin, process conditions, and whether it is unbleached, bleached, or filtered. Its consistency is deterrnined chiefly by its oil, free fatty acid, and moisture content. Properly refined lecithin has practically no odor and has a bland taste. It is soluble in aflphatic and aromatic hydrocarbons, including the halogenated hydrocarbons however, it is only partially soluble in aflphatic alcohols (Table 5). Pure phosphatidylcholine is soluble in ethanol. [Pg.98]

Rubbers. Plasticizers have been used in mbber processing and formulations for many years (8), although phthaHc and adipic esters have found Htde use since cheaper alternatives, eg, heavy petroleum oils, coal tars, and other predominandy hydrocarbon products, are available for many types of mbber. Esters, eg, DOA, DOP, and DOS, can be used with latex mbber to produce large reductions in T. It has been noted (9) that the more polar elastomers such as nitrile mbber and chloroprene are insufficiendy compatible with hydrocarbons and requite a more specialized type of plasticizer, eg, a phthalate or adipate ester. Approximately 50% of nitrile mbber used in Western Europe is plasticized at 10—15 phr (a total of 5000—6000 t/yr), and 25% of chloroprene at ca 10 phr (ca 2000 t/yr) is plasticized. Usage in other elastomers is very low although may increase due to toxicological concerns over polynuclear aromatic compounds (9). [Pg.129]

To improve processing and to plasticize the mbber compound, numerous processing agents have been used over the years, eg, petroleum and ester plasticizers, resins and tars, Hquid mbber peptizers, peptizers, fatty acids and derivatives from vegetable oils, and polyethylene and hydrocarbon waxes. [Pg.245]

In the rubber industry hydrocarbon oils are often used to reduce the softness and facilitate the processing of hydrocarbon rubbers. These appear to have a small interaction with the polymer but spacing effects predominate. Such materials are generally referred to as softeners. The rubber industry, like the plastics industry, commonly uses the term plasticisers to describe the phthalates, phosphates and sebacates which are more commonly used with the more polar rubbers. [Pg.132]

Hydrolysis of Chlorinated Hydrocarbons. The production of oxygenated aliphatics by the hydrolysis of chlorinated hydrocarbons includes the synthetic glycerol process and the amyl alcohols process. Glycerol (7) is made from propylene via allyl chloride (CH2 CHCH2C1), and competes with glycerol made from fats and oils for use in dynamite and alkyd resins, as a tobacco humectant and cellophane plasticizer, in cosmetics and pharmaceuticals, and for other applications. Amyl alcohols have been made since 1926 by the alkali hydrolysis of a mixture of amyl chlorides, made by the chlorination of pentanes from natural gasoline. Production from this source far exceeds the supply from the fusel oil by-product of fermentation processes. Amyl alcohol and its derivatives are used mainly as solvents. [Pg.297]

Furan-2-carbaldehyde (furfural) is widely used in the vegetable oil, plastics, rubber and petroleum industries as well as being a versatile starting material for furan syntheses. It is the major source of commercial furans. It is used to extract unsaturated hydrocarbons from hydrocarbon mixtures, a process important in the purification of petroleum and vegetable oils. The chemistry of furfural has been extensively studied because of its industrial importance and availability. [Pg.705]
