HFO foaming agent technology revolution and environmental protection trend
Against the background of increasingly stringent global environmental regulations, hydrofluoroolefins (HFOs), as the fourth generation of physical foaming agents, are rapidly replacing traditional HCFC and HFC foaming agents. With its extremely low global warming potential (GWP<1) and zero ozone depletion characteristics (ODP=0), the HFO foaming system has become a key technical path for the polyurethane industry to achieve sustainable development. According to the latest market research, by 2026, the market share of HFO in polyurethane foaming agents is expected to grow to 58%, with a compound annual growth rate of 12.3%.
Core technical advantages of HFO foaming system
1. Breakthrough in environmental performance
- GWP value <10: more than 99% lower than HFC-245fa (GWP=1030)
- Zero ODP: does not damage the ozone layer and meets the requirements of the Montreal Protocol
- Low VOC emissions: meets green building certification standards such as LEED and BREEAM
2. Excellent insulation performance
The gas phase thermal conductivity of HFO foaming agent (0.013-0.015 W/m·K) is significantly better than that of traditional foaming agents, which can reduce the overall thermal conductivity of polyurethane foam by 15-20%, bringing significant energy-saving effects to refrigerators, building insulation and other fields.
3. Process adaptability challenges and solutions
Due to its special physical properties (such as boiling point, heat of vaporization, etc.), HFO blowing agents put forward new requirements for polyurethane formulations and processes:
- More precise reaction kinetics control is required
- Optimize the balance between foaming and gelling
- Improve the uniformity of cell structure
- Enhance substrate bonding performance
This is the value of our MXC-70 catalyst developed specifically for HFO systems.
