Normal Pentane is used in consumer merchandise such as spot lifters, cleaners and foaming shave gels and in commercial products such as a blowing agent for expanded polystyrene (foam) insulation. It may also be used as a solvent (extra pure grade) in laboratory, chemical analysis, and other settings where a highly volatile non-polar solvent is needed.

Product Applications

In addition to the above mentioned, Normal Pentane (Pentane) is used principally as a blowing agent in foam production, as a propellant in aerosols and as reaction media for polymerisation processes. It is also used in the laboratory as solvents that can be conveniently and rapidly evaporated.

Highest quality 99+% n-Pentane. Pentanes are relatively inexpensive and are the most volatile liquid alkanes at room temperature, so they are often used in the laboratory as solvents that can be conveniently and rapidly evaporated.

However, because of their nonpolarity and lack of functionality, they dissolve only nonpolar and alkyl-rich compounds. Pentanes are miscible with most common nonpolar solvents such as chlorocarbons, aromatics, and ethers. They are often used in liquid chromatography.
