From HCFC-141b to n-Pentane: The Global Shift in Polyurethane Foam Blowing Agents
The polyurethane (PU) foam industry is undergoing a rapid transformation. With the global phase-out of HCFC-141b, manufacturers are seeking sustainable alternatives that maintain high performance while meeting environmental standards.
That’s where n-Pentane comes in — a clean, efficient, and cost-effective blowing agent that’s redefining insulation foam production.
Why n-Pentane is replacing 141b:
- Environmentally compliant: No ozone depletion potential (ODP = 0) and significantly lower global warming potential (GWP).
- Excellent insulation performance: Ensures fine and uniform cell structure for superior thermal efficiency.
- Lower production cost: Competitive raw material pricing and easy integration with existing foaming equipment.
- Proven applications: Widely used in PU sandwich panels, air duct insulation boards, and cold storage systems by leading manufacturers worldwide.
As demand grows for green insulation materials, switching to n-Pentane is not just a regulatory requirement — it’s a strategic advantage.
Make your insulation greener, safer, and more efficient.
Choose n-Pentane — the new standard for rigid polyurethane foam production.
