Application
1. Pentane is the main blowing agent used in the production of polystyrene foam and other foam materials. Normally, mixtures of n-pentane, isopentane, and more and more cyclopentane are used for this purpose.
2. Due to its low boiling point, low cost, and relative safety, pentane is used as the working medium of geothermal power stations. It is also used in the composition of mixed refrigerants.
3. Pentane is also used as an active ingredient in some pesticides.
