Environmental regulation or restriction . . . .
Environmental regulation is now driving commercialization
Markets Served:Mobile and Stationary Air conditioning, Refrigeration, Insulation Foam for Buildings and Electrical Appliances, Cleaning Solvents, Nuclear Power, Aerosols, Heat Pumps, Geothermal and Solar Renewables
and Very High Global
Non-Ozone Depleting but has High Global Warming Potential
Low-Global-Warming Potentials and No Ozone
Innovation Tied to Environmental Compliance
HCFC’s successfully phased out in many countries
Attributes support governments’ and industry’s preferences
Honeywell HBA-2 Blowing Agent promising low GWP molecule
trans – 1,3,3,3 – tetrafluoropropene
Non-ODS / Low GWP / Non-Flammable / Low POCP
= Environmentally Sustainable Molecule =
HFC-245fa: Low capital, medium term safe route to ODS management
Transitioning: HCFC-141b HFC-245fa HBA-2 maintains energy efficiency
Low water formulation
High water formulation
Why are HFC-245fa and HBA-2 blowing agents low capital investment?
Why are Non-HFC (hydrocarbon & methyl formate) blowing agents challenging?
HBA-2 is a LOW capital investment, near ‘drop-in’ transition from HFC-245fa
* LTTR: Long Term Thermal Resistance
Non-HFC PUR requires additional costs to achieve equal performance
Environmental solutions have/will meet regulatory needs timing
