Description

Cyclopentane CAS NO 287-92-3 is a highly volatile, saturated alicyclic hydrocarbon with a simple five-membered ring structure. Its low boiling point and excellent blowing agent properties make it a critical material for producing energy-efficient, environmentally friendly insulation foams. This versatile chemical intermediate is essential for manufacturers in the polyurethane foam, refrigerant, and specialty chemical synthesis industries seeking reliable, high-purity raw materials.

Application

• Primary blowing agent for the production of polyurethane (PU) and polyisocyanurate (PIR) rigid insulation foams, valued for its zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
• Key component in formulations for appliance insulation (refrigerators, freezers, water heaters) and construction panels.
• Used as a solvent in various chemical processes and laboratory applications due to its non-polar nature.
• Acts as a precursor or intermediate in the synthesis of pharmaceuticals, fragrances, and other specialty chemicals.
• Employed as a fuel additive and in some refrigerant blends.

Quality Control

Our Cyclopentane is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity, water content, and non-volatile residue. Our quality commitment aligns with global standards for industrial and foam-grade chemicals, ensuring reliable performance in your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is below 30°C (86°F).
