Key Applications of *n*-Pentane (C₅H₁₂)
1. Foam Blowing Agent (Major Use: ~60%)
Expanded Polystyrene (EPS): Creates lightweight insulation for construction and packaging.
Polyurethane (PU) Foams: Alternative to HCFCs/HFCs (low GWP).
2. Industrial Solvent (~20%)
Electronics Cleaning: Degreasing circuits/semiconductors.
Adhesives & Coatings: Fast-evaporating carrier solvent.
Laboratory Use: HPLC/GC analysis (high-purity grade).
3. Fuel & Energy (~15%)
Gasoline Additive: Boosts octane rating (blended in refineries).
LPG Component: Mixed with butane/propane for burners.
4. Chemical Feedstock (~5%)
Pentene Production: For synthetic rubber (tires, seals).
Pharmaceuticals: Intermediate in drug synthesis.
