Opteon™ 1100
Foam Blowing Agent

Product Information
Introduction
In response to growing needs for high performance productswith reduced environmental impact, Chemours hascommercialized a new blowing agent, Opteon™ 1100, based onhydrofluoroolefin (HFO) chemistry. Opteon™ 1100 provides an
excellent match of physical properties and performance
characteristics. Opteon™ 1100 offers a sustainable solution tomeet changing regulatory requirements with enhanced
performance to replace hydrofluorocarbons (HFCs),
hydrochlorofluorocarbons (HCFCs), and hydrocarbons (HCs).
• Ozone Depletion Potential (ODP) = 0 (no chlorine)• Broadly Registered in All Relevant Regions• Global Warming Potential (GWP) 100 yr ITH = 2.0 (AR5)• Atmospheric Lifetime = 22 days (NOAA)• Photochemical Ozone Creation Potential (POCP) = 3.4• Molecular Weight = 164

An Effective and Safe Alternative
Opteon™ 1100 foam blowing agent features physicalproperties that make it an extremely effective replacement for
HFCs, HCFCs, and HCs in urethane-based foam applications.
These properties include an optimum boiling point, low vapor
thermal conductivity, and low permeation rate. Opteon™ 1100
offers the added benefits of being nonflammable and having afavorable toxicity profile (Table 1). This provides increased
safety in use for both workers and consumers.

Superior Chemical Stability and Shelf Life
Opteon™ 1100 foam blowing agent chemical stability has
been evaluated by Chemours in both B-side formulations
and foams aged at elevated temperatures for up to 6months. These tests have demonstrated the excellent
chemical stability of Opteon™ 1100 in polyurethane
systems and foams. The high chemical stability of Opteon™
1100 results in longer B-side formulation shelf lives
compared to those employing other blowing agents.
Opteon™ 1100 is also compatible with a wide range ofamine catalysts, therefore, allowing for a high degree offlexibility in formulation reactivity and application
customization. The high chemical stability of Opteon™ 1100
has been confirmed in field testing and large scale trials.

Opteon™ 1100 Materials Compatibility

Opteon™ 1100 Polyol Compatibility

Materials compatibility testing for up to 14 days has shownthat Opteon™ 1100 foam blowing agent is compatible withthe metals, elastomers, and plastics typically used in thestorage, handling, and manufacture of foams. No equipment
or material of construction changes have been required infield testing and larger scale trials.

As seen in Table 2, Opteon™ 1100 exhibits good solubility
in a broad range of polyols. Opteon™ 1100 solubility isgenerally high in polyether polyols, being completely soluble
in most. The solubility of Opteon™ 1100 in polyester
polyols is generally lower, ranging from 5 to 30 weight % atroom temperature.

Physical Properties

The physical properties of Opteon™ 1100 foam blowing
agent compare quite closely to those of HCFC-141b,
a major foam blowing agent of choice for polyurethane
foams, prior to its phaseout under the Montreal Protocol
due to its ozone-depleting properties. Two key Opteon™
1100 properties, vapor pressure and vapor thermal
conductivity, are shown in Figures 1 and 2. Opteon™ 1100
is also nonflammable as determined by ASTM E681 – evenat temperatures up to 100 °C (212 °F).

As a nonflammable, room temperature liquid with excellent
miscibility in many polyols, Opteon™ 1100 provides a safe,
easy to handle foam blowing agent for polyurethane
applications. The low vapor thermal conductivity and low
permeation of Opteon™ 1100 results in the production ofpolyurethane foams with improved initial and aged
k-factors compared to foams prepared with incumbent
HFC, hydrochlorofluoroolefin (HCFO), or HC blowing agents.
Customer field trials with Opteon™ 1100 havedemonstrated superior application behavior coupled withimproved, long lasting k-factors.
