HFO-1234yf HFO-1234ze(E) Vapor Pressure Vs. Temperature Vapor Pressure Vs. Temperature Pressure, MPa Pressure, MPa Temperature, oC Temperature, oC • Environmental • ODP = 0 • GWP100 = 4 • Atmospheric Life: 11 days • Toxicity & Regulatory Approvals • Low toxicity : Honeywell PEL = 400 ppm • Key toxicity testing complete; good results • Notified to ELINCS, hence registered to REACH. Submit HPV update by Dec 1. • U.S. PMN & SNAP applications in progress • Preparing Japanese notification • Environmental • ODP = 0 • GWP100 = 6 • Atmospheric Life: 18 days • Toxicity & Regulatory Approvals • Low toxicity : Honeywell PEL = 1,000 ppm • Significant testing completed; good results • EU Notification Annex VIII Level 1 • ELINCS 471-480-1 • U.S. PMN & SNAP applications in progress • Preparing Japanese notification Excellent Environmental & Toxicological Properties
1234yf – The Leading Replacement For R-134a In Auto A/C • Excellent environmental properties • Very low GWP of 4, Zero ODP, Favorable LCCP • Atmospheric chemistry determined and published • Low toxicity, similar to R-134a • Low acute and repeated exposure toxicity • Significant testing completed • Initial PEL 400 ppm • System performance very similar to R-134a • Excellent COP and Capacity, no glide • From both internal tests and OEM tests • Thermally stable and compatible with R-134a components • Potential for direct substitution of R-134a • Mild flammability (manageable) • Flammability significantly less than 152a • Expect “A2L” ISO 817 classification versus “A2” for 152a • Potential to use in a direct expansion A/C system • Global Solution • Lowest total cost of transition than any alternative • Good performance in all climates, and car sizes
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 (1-generation 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.
