Opteon™1100 Commercial Situation

• Registered to meet regulatory conversion around

the globe

• Opteon™ 1100 plant is operational in Changshu,

Jiangsu Province, PRC

• Product available in drums or iso-containers

Purpose: Compare spray application performance at equal weight loadings as

a function of formulation storage time

• The mass of HFC or HFO blowing agent was held constant. The density for the Opteon™ 1100 (FEA-1100) sample was adjusted by using water.

• Graco HV-R Reactor, 125F hoses, 1600 psig, AR4242 mix chamber

• Both systems were aged in 5 gallon pails in a controlled laboratory environment (room temp).

Summary of Cold Adhesion Study

• Combination of Opteon™ 1100 solubility, boiling point and

latent heat impact consistent cold adhesion

• Multiple factors can provide improvements:

– Adhesion promoters

– Solubility additives

– Type and level of gel catalysts

– Type and level of surfactant

– Application conditions

• Balanced approach appears promising for new levels of

improvement

CASE STUDY : APPLICATION DETAILS

• Formulation: medium density (32 kg/m3) spray polyurethane foam

based on Opteon™ 1100 as a high performance insulation product.

• Application: The application was completed over a period of several

days due to weather conditions and the size of the installation job.

– Interior wall cavities filled to 2 inches in 1 lift

– Roofline to 5.5 inches in 3 lifts.

CASE STUDY : PERFORMANCE DATA

• Performance: In comparison to previous HFC-245fa

based formulations, the new Opteon™1100 system

applied easily and with no problems associated tip fouling,

rise time, substrate adhesion or surface appearance.

From a yield perspective, approximately 4500 board feet

per drum set was obtained and increased
