Isobutane

Isobutane (CAS 75-28-5 ), also recognized in refrigerant markets as R600a and in food applications as E943b , is a liquefied hydrocarbon gas used as a propellant and solvent carrier. Its low boiling point and clean vaporization profile make it a practical choice where residue-free delivery or efficient heat transfer is required across multiple industrial sectors. In food and aerosol manufacturing, E943b functions as a propellant in spray products, delivering controlled pressure without leaving residue in the final product for consumers. Refrigeration systems, particularly domestic appliances and light commercial units, use R600a as a natural refrigerant with low global warming potential as a preferred alternative to synthetic HFCs. In the oil and gas sector, isobutane is used as a blending component in alkylation processes to produce high-octane gasoline fractions for the automotive and energy industries. Aerosol personal care and household product manufacturers also rely on it as a solvent carrier to dissolve and uniformly disperse active ingredients in various formulations. Isobutane is supplied as a liquefied gas in pressurized cylinders, ISO tanks, and bulk transport vessels. Refrigerant-grade R600a is available to high purity specifications. Food-grade supply conforming to E943b specifications is available for aerosol and propellant use in regulated food contact applications and meets necessary safety requirements.
