Description

Neopentane is a highly branched, saturated hydrocarbon isomer of pentane, known for its unique structural and physical properties. Its high volatility and low boiling point make it a valuable specialty chemical and physical blowing agent in polymer foams. This compound is essential for industries requiring precise control over foam density and insulation properties, such as advanced polymer manufacturing and refrigeration. Key markets include producers of expanded polystyrene (EPS), polyurethane (PU) foams, and specialized laboratories utilizing it as a non-polar solvent or calibration standard.

Application

• Primary use as a physical blowing agent in the production of expanded polystyrene (EPS) and polyurethane (PU) rigid foams for insulation.
• Key component in refrigerant blends and aerosol propellants due to its favorable thermodynamic properties.
• Used as a non-polar solvent and reaction medium in specialized organic synthesis and laboratory research.
• Employed as a calibration standard in gas chromatography (GC) and other analytical instrumentation.
• Acts as a feedstock or intermediate in the synthesis of other high-value, branched hydrocarbon compounds.
• Utilized in the formulation of certain fuel additives and high-octane blending components.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and flammable nature, store in a cool, well-ventilated area away from heat, sparks, and open flames. Keep container tightly sealed when not in use to prevent evaporation and contamination. Storage temperature should not exceed 25°C (77°F).
