DuPont and Honeywell feel comfortable with all toxicity
test results conducted to date and will continue the
commercialization of HFO-1234yf for use in MAC
Based on toxicity testing conducted to date, including the second
species developmental and the 2-generation reproductive (1generation interim results) studies, we believe HFO-1234yf will not
be classified as a developmental or reproductive toxin, and it will
likely be classified as ASHRAE Class A (low toxicity).
There appear to be no health safety hazards or properties that
would preclude the safe use of HFO-1234yf in MAC applications.

HONEYWELL BEGINS COMMERCIAL SHIPMENTS OF VERY LOWGWP BLOWING AGENT FOR ONE-COMPONENT FOAM AND
AEROSOL APPLICATIONS IN EUROPE
Development follows clearance from the EU to import quantities of
HFO-1234ze last year based on positive toxicity results
SAN ANTONIO, Texas. - Oct. 1, 2008 — Honeywell (NYSE: HON) announced today it
has fully commercialized HFO-1234ze, its novel low-global-warming-potential (GWP) blowing agent
for one-component foam and aerosol applications, in Europe.
HFO-1234ze has zero ozone-depletion potential and has a GWP of only six, which is well
below the threshold of 150 set by the EU F-Gas regulation. The material is not classified as dangerous
under EU Directive 67-548-EEC. It serves as a direct replacement for HFC-134a in one-component
foam and aerosol applications.
“We are pleased to provide an environmentally superior and energy-efficient solution for
foam and aerosol manufacturers,” said Rene Mueller, managing director of Fluorine Products for
Europe, the Middle East, Africa and India. “We are committed to helping our customers meet
current and potential regulatory requirements.”
“Any replacement material must maintain or improve energy efficiency and be a less potent
greenhouse gas,” said Ian Shankland, technology leader for Honeywell’s low-GWP initiative. “Our
next-generation blowing agent meets these criteria while offering similar performance properties as
its predecessor.”
Honeywell made the announcement at the Polyurethanes 2008 Technical Conference, which is
sponsored by the U.S. Center for the Polyurethanes Industry (CPI). Honeywell is presenting a
technical paper at the event, which will further update attendees on full commercialization
developments.

1234ze(E) One-Component Foam
• One-component polyurethane foam used to
seal cracks and openings in construction
applications.
• Foam is delivered and expanded using HFC134a from a pressurized container
• EU F-Gas regulation requires that onecomponent foam made after July 4, 2008 use
a blowing agent with a GWP < 150
• EU F-Gas regulation requires novelty
aerosols made after July 4, 2009 use a
propellant with a GWP < 150
