  1. DuPont™ FEA-1100: Zero ODP, Low GWP, Non-Flammable Alternative for HCFC-141b Helen Walter-Terrinoni Nov 12, 2010

  2. Desired Properties for HCFC-141b Phase-out • Environmentally sustainable • Zero ODP & Low GWP • Safety & Handling • Low Toxicity • Chemical stable • Non-flammable • Suitable boiling point (25C - 35C) • Good insulation performance • Low vapor thermal conductivity or Lambda • Flexibility to use high level of FEA • Low conversion cost • Potential drop-in to existing process & equipment • Potential drop-in to existing formulations

  3. HCFC-141b Phase-out Options Next Generation Low GWP Zero ODP HIGH ODP LOW ODP ZERO ODP HFC-245fa HFC-365mfc Pentanes Methyl Formate Methylal H2O(CO2) Mixtures FEA-1100 CFC-11 HCFC-141b Next Generation Low GWP HBA-2 AFA-L1

  4. FEA-1100 – a Sustainable & Balanced Option FEA-1100 (HFO-1336mzz) • ODP = 0 • GWP 100 yr ITH = 9.4 (NOAA) • ATM lifetime = 24 days (NOAA) • Nonflammable (ASTM E 681 at 60oC & 100oC) • b.p = 33 oC • λ= 10.7 mW/mK @ 25 oC • MW = 164 CF3CH=CHCF3

  5. Challenges to Develop Low GWP FEAs Reduce GWP while maintaining other desired properties FEA-1100

  6. Foam Expansion Agent Property Comparison

  7. HCFC-141b Phase-out Option Comparisons • FEA-1100 – a zero ODP & low GWP FEA with desired properties

  8. Thermal Conductivity and Vapor Pressure Comparisons • Low vapor thermal conductivity over broad temperature range • Lowest thermal conductivity when temperature >150F Vapor pressure is very close to HCFC-141b

  9. FEA-1100 vs Other Zero ODP FEAs FEA-1100 has the best insulation performance

  10. FEA-1100 Impact on FEA Mixtures • Adding FEA-1100 to other zero ODP FEAs • Same foam formulation & equi-molar FEAs • FEA-1100 improves R-value

  11. FEA-1100 Mixture – Polyester Polyol • Blend FEA-1100 to 50/50 cyclopentane(c-C5)-isopentane(i-C5) mixture • Same foam formulation & equi-molar FEAs • FEA-1100 improves performance

  12. FEA-1100 vs HCFC-141b & HFCs Superior insulation performance compared to HCFC-141b & HFCs

  13. FEA Level & R-value (FEA-1100 vs HFC-245fa) • High level of FEA-1100 can be used without vapor pressure or flammability limitation • High level of FEA-1100 can potentially improve insulation performance * High level of HFC-245fa may cause pressure exceed drum pressure rating

  14. Chemical Stability – Polyether at 50 oC for 6 months FEA-1100 is stable in a generic polyether formulation after 6 months storage at 50 oC

  15. Chemical Stability – Polyester at 50 oC for 6 months FEA-1100 is stable in a generic polyester formulation after 6 months storage at 50 oC

  16. Polyol Solubility FEA-1100 is soluble in commonly used polyols

  17. Material Compatibility - Metal FEA-1100 is compatible with commonly used metals • Changes after 2 weeks at 100oC (212oF) in FEA-1100

  18. Material Compatibility - Elastomers FEA-1100 is compatible with commonly used elastomers • Changes after 2 weeks at room temperature in FEA-1100

  19. Material Compatibility - Plastics FEA-1100 is compatible with commonly used plastics • Changes after 2 weeks at room temperature in FEA-1100

  20. Toxicity Assessment FEA-1100: Favorable Results 4-hr LC50: Very Low acute toxicity Skin Irritation: Non - irritating Ames Test: Non - mutagenic Chromosomal Aberration: No genetic material damage Cardiac Sensitization: Favorable cardiac sensitization potential profile 28-Day Repeat Inhalation: Favorable repeated inhalation profile 90 Day/ developmental:Favorable repeated inhalation profile consistent with 28-day test result
