The document discusses alternatives to HCFC-141b for use as blowing agents in insulating foam, noting that Honeywell has developed lower global warming potential (GWP) replacements such as HFOs and HBA2 that offer improved energy efficiency, safety, and environmental profile compared to other alternatives like hydrocarbons and HFCs currently used as 141b replacements. Honeywell has commercialized several of these new blowing agents for use in applications like refrigeration, stationary air conditioning, spray foam, and extruded polystyrene foam. The document presents performance data showing that HBA2 provides energy efficiency gains of 10-12% compared to
