Solstice® Liquid Blowing Agent

Solstice LBA Conversion Manual

A Low GWP Foam Blowing Agent with All the Benefits of HFCs

Solstice Liquid Blowing Agent (LBA) is our latest advancement in foam blowing agent technology. Based on hydrofluoro-olefin (HFO) technology, Solstice LBA has a global warming potential (GWP) of 1, 99.9% lower than HFC blowing agents. It is a cost-effective replacement for other liquid foam blowing agents.

Honeywell Solstice LBA is:

  • Non-ozone-depleting
  • Nonflammable (ASTM E-681 and EU A11)
  • Listed under the U.S. EPA’s Significant New Alternatives Policy (SNAP) program to replace ozone-depleting substances
  • Listed on the TSCA inventory/registered under REACH
  • VOC-exempt (per U.S. EPA)
  • Manufactured in the U.S.
  • Foam Performance
  • Physical Properties
  • Lower Conversion Cost
  • Environmental
  • Nonflammable
  • Atmospheric Impact

Next-Generation Technology

The energy efficiency benefits of Solstice LBA, combined with its low environmental impact and nonflammability, make it the right replacement for hydrocarbons, HFCs, and HCFCs. Solstice LBA performs better than hydrocarbons in refrigerator insulation and other foam applications by delivering:

  • Better low-temperature efficiency that saves energy costs.
  • Lower capital costs by avoiding expensive flammability risk mitigation equipment and preventive maintenance

Compared to HFCs, it provides:

  • Superior thermal performance
  • Higher foam yield
  • Improved sprayability

Solstice LBA exhibits certain physical properties similar to HFC-245fa (boiling point, flammability) and superior to cyclopentane. It has a GWP of 1, 99.9% lower than HFCs it replaces and equal to C02. See table for comparisons.

Lower Conversion Cost

Solstice Liquid Blowing Agent is a near drop-in replacement for liquid HFC blowing agents. It is liquid at room temperature and can be used in most existing foam equipment, regardless of current blowing agent used, with little or no modification.

Replacing existing foam blowing agents with Solstice LBA eliminates the need for large capital conversion costs. And our foam blowing agent does not require costly hydrocarbon storage and handling or risk mitigation equipment.

The flammability characteristics and VOC mitigation required with other foam blowing agents (such as hydrocarbons) make them less desirable as replacements for existing blowing agents.

The Best of HFCs, Plus Ultra-low GWP

Honeywell’s fourth generation foam blowing agent was formulated to have a significantly lower global warming potential (GWP) and improved energy efficiency while retaining nonflammability and ease of conversion.

Honeywell Solstice LBA is a near drop-in replacement for liquid HCFC, HFC, hydrocarbons and other foam blowing agents. In addition, these properties continue to differentiate Honeywell foam blowing agents as the best choice for high performance rigid foam insulation applications and for those applications where a flammable foam blowing agent is unsafe, too costly to use, or fails to provide the desired foam performance.

Solstice LBA is distinctly different from hydrocarbon foam blowing agents in flammability characterization. The shipment, storage, handling and processing of Solstice LBA does not require flammability risk mitigation. Flammable foam blowing agents, such as cyclopentane, require flammability risk mitigation, which can add significant capital costs.

Solstice LBA is classified as a nonflammable liquefied gas by the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), United States Department of Transportation (DOT), International Air Transport Association (IATA), and International Maritime Dangerous Goods Code (IMDG) codes and regulations. Solstice LBA is designated as a Class 2 (nonflammable) Liquefied Gas per U.S. DOT definition (49 CFR 173.115). A summary of flammability characteristics for Solstice LBA can be found in the table.

Ultra-low GWP of 1

Solstice LBA is unsaturated (double bond structure) with a short atmospheric lifetime. This has a dramatic, positive impact on its environmental properties.
