Description

Cyclopentane (CAS 287-92-3 ) is a saturated cyclic hydrocarbon used primarily as a blowing agent and specialty solvent across several industrial sectors. Its low boiling point and high purity availability make it a preferred choice where controlled volatility is a process requirement. In rigid polyurethane foam manufacturing, it is the dominant blowing agent for producing insulation panels used in refrigerators, freezers, and cold-chain equipment. It serves as a critical replacement for older HFC-based alternatives under modern environmental regulations. Pharmaceutical manufacturers use it as a reaction solvent and extraction medium in API synthesis where a non-polar, low-residue solvent profile is required. It ensures high efficiency in chemical processing while maintaining the integrity of sensitive molecular structures. In specialty fragrance and flavor formulations, it functions as a carrier solvent for delivering volatile aroma compounds at controlled evaporation rates. Lubricant formulators also use it as a process solvent during synthesis and blending of cycloparaffinic base stocks. The product is supplied as a liquid, typically in drums, IBCs, and bulk tanker quantities to meet various industrial scales. Standard commercial grades include high-purity technical grade (95%+) and polyurethane foam-grade with tightly controlled purity specifications. These specifications are designed to meet specific blowing agent performance requirements and thermal conductivity standards. Pharmaceutical-grade material is available to buyers requiring documentation aligned with ICH solvent guidelines for manufacturing. Our supply chain ensures consistent quality and availability for large-scale industrial applications. We provide comprehensive technical data sheets and safety documentation to support the integration of this hydrocarbon into your specific production workflows.
