Description

n‑Pentane, 95% is a high‑purity aliphatic hydrocarbon widely used in PU/PIR foam blowing, chemical processing, and industrial solvent applications. This grade contains a minimum of 95% normal pentane, offering fast evaporation, high volatility, and excellent solvency for non‑polar systems. It provides stable performance for foam production, extraction processes, and hydrocarbon blending. The product is supplied in UN‑approved steel drums to ensure safe handling, compliant storage, and reliable international shipment.

Key Features:

• Purity: n-Pentane ≥95%

• Balanced Composition: Optimal ratios of Isopentane and Cyclopentane

• Low Impurities: Butanes and lighter ≤0.5%, Aromatics ≤100 ppm, Hexanes and heavier ≤0.5%

• Packaging: Available in drums and ISO tanks for flexible industrial use

Applications:

• Polyurethane foam production

• Insulation materials

• Industrial and construction foams

• Other foaming agent applications where high-purity pentane is required

Benefits:

• Delivers uniform foam quality

• Enhances production efficiency

• Low environmental impact due to minimal impurities

• Reliable performance in large-scale industrial processes

Handling & Safety:

• Store in a cool, dry, and well-ventilated area

• Keep away from heat and open flames
