aliphatic compound

Any organic chemical compound in which the carbon atoms are joined in straight chains, as in hexane (C6H14), or in branched chains, as in 2-methylpentane (CH3CH(CH3)CH2CH2CH 3).

Aliphatic compounds have bonding electrons localized within the vicinity of the bonded atoms. Cyclic compounds that do not have delocalized electrons are also aliphatic, as in the alicyclic compound cyclohexane (C6H12) or the heterocyclic piperidine (C5H11N). Compare aromatic compound.

Among the principal aliphatic compounds are the alkanes (paraffins), which include methane, ethane, pentane, petrol, kerosene, lubricating oil, and paraffin wax; the alkenes (olefins), including ethene (C2H4); the ethynes (for example, acetylene C2H2); the alcohols, ethers, ethanoic and other acids, esters (for example ethyl acetate), certain classes of amines, the carbohydrates, such as starch, sugar and cellulose; and the fats.

Key statement: A rubber composition comprising (A) an organopolysiloxane end-capped with alkenyldialkylsiloxy, radicals and free of aliphatic unsaturation, (B) an organipolysiloxane containing three alkenyl radicals on molecular side chains, (C) an organohydrogenpolysiloxane, (D) fumed silica and (E) an addition reaction catalyst forms a seal member having improved strength and reduced compression set and useful for sealing a polymer electrolyte fuel-cell separator.
One highlight will be a novel aliphatic PUR cast elastomer technology said to enable production of highly transparent parts with unique property profiles.
What's more, these transparent materials, based on aliphatic isocyanates and polyesters, can be pigmented with any color.
