A new gas that warm earth less

01 Mar 2011

USA’s Environmental Protection Agency approved a new low-global-warming blowing agent for foam and aerosols applications.


New Horizons - Gas producer Honeywell announced that its new low-global-warming-potential product (HFO-1234ze) has been accepted for use in foam and aerosol applications by the US Environmental Protection Agency.

The new product, hydrofluoroolefin (HFO-1234ze), is non-flammable, non-ozone depleting and has a global warming potential (GWP) of 6.

HFO-1234ze can replace HFC-134a (with a GWP of 1,430) and HFC-152a (with a GWP of 142) in aerosol applications, extruded polystyrene board (XPS), rigid polyurethane foam, and one-and two- component insulating and sealant foam.

"End consumers and the environment all benefit from the EPA's acceptance of this low-global-warming-potential fluorocarbon," said Terrence Hahn, Vice President responsible from fluorine products business of Honeywell.

Earlier in 2010, Honeywell launched another low-GWP product, HFO-1234yf, for use in automobile air conditioners.

Fluorocarbon technology benefits society through superior energy efficiency performance in cooling and insulating applications.

Same performance, lower emission

By reducing fuel consumption, fluorocarbons directly reduce greenhouse gas emissions from heating, cooling and electrical power generation, and are cost-effective for the end user compared with fluorocarbon alternatives.

In addition, fluorocarbons are mostly non-flammable and have a low order of toxicity, which makes them significantly safer in use than alternatives such as hydrocarbons and ammonia that are either extremely flammable or highly toxic.

Hydrofluoroolefins (HFOs) are a family of unique products that offer similar performance properties to today's most widely used refrigerants, blowing agents and aerosol propellants, but with the added benefit of having very low global warming potentials.

HFO-1234ze is currently used in Europe and Japan in a variety of foam and aerosol applications.

UNDP Turkey’s project to use the gas in XPS sector

UNDP, Republic of Turkey Ministry of Environment and Forestry and private sector firm B-Plas AŞ were launched a project to use this new gas in XPS sector in 2010.

The affectivities of this gas on XPS product will be determined according to TS EN 13164 standard with the same production processes.

The completion of the project has been planned for the end of July 2011.

Project partners are UNDP, Ministry of Environment and Forestry and B-Plas AŞ.
