Honeywell Gearing Up to Produce New Blowing Agent

MORRISTOWN, NJ — Honeywell has announced that it has filed a Notice of Commencement of Manufacture (NOC) with the U.S. Environmental Protection Agency (EPA) for a new-generation blowing agent, HFC-245fa.

The NOC is the final step in the process necessary to approve a new chemical and have it listed on the Toxic Substance Control Act (TSCA) Inventory.

HFC-245fa is a non-ozone depleting blowing agent designed primarily to replace HCFC-141b, which is used in a variety of rigid insulating foams. HCFC-141b is being phased out as part of the Montreal Protocol.

In addition, Honeywell announced that it is providing semi-commercial quantities of the blowing agent to the U.S. foam industry before the startup of its new commercial facility. “The next step is to work closely with industry to ensure proper supply, effective conversions, and to assist in technical development of formulations using HFC-245fa,” said Carol Bibb, specialty fluorines business director.

Honeywell also noted that its new HFC-245fa manufacturing facility in Geismar, LA, is on target for a mid-2002 startup. The company is working with Kvaerner Engineering on plant design and construction. Also, the nearby Vulcan Chemicals plant being built to supply key feedstock for production is on schedule for completion in early 2002.

According to the company, HFC-245fa is proving to be an alternative to HCFC-141b for a number of applications and industries. At the recent Polyurethanes Conference 2000, several papers highlighted the advantages of HFC-245fa in various foam applications, including appliance, spray foam, and boardstock.
