The specific volume is 0. Protect it from solar rays and avoid exposing it to temperatures over 50 °C. Introduction Substance 2,3,3,3-tetra uoropropene (R1234yf) relates to a group of Online Propane Density Calculator. 5 SECTION 10. This latter effect has resulted in a higher shaft torque required for the case of R1234yf, as shown in Fig. 1 Flammable Propane R290 A3 2. STABILITY AND REACTIVITY 10. It is obvious that R1234yf and R444A gases exhibit nearly the same density versus pressure distribution, but R445A has greater the density values by 4. 438 R-1234yf belongs to a new family of HFOs (hydro-fluoro-olefins) that have a low GWP. 1 Revision Date: 03/26/2019 SDS Number: 1335696-00043 Date of last issue: 11/19/2018 Date of first issue: 02/27/2017 3 / 14 Dizziness confusion Lack of coordination Drowsiness Unconsciousness Contact with liquid or refrigerated gas can cause cold burns and frostbite. [22] evaluated experimentally and compared the performance of HFC-134a to HFO-1234yf and HFO-1234ze, and concluded that HFO-1234yf had 2. 231 0. 12 × 10–8 m3⋅kg–1. 1 g/cm³ (25°C) Solubility : Water: 198. Relevant identified uses . Table 2. From the coupling factor φ and its variation with density it is possible to estimate the specific magnetic susceptibility of a fluid as detailed by McLinden et al. 21 2. 02. Protect it from solar rays and avoid exposing it to temperatures over 50 °C. 500 1. In fact, Idemitsu PAG’s structure is so exceptional, it is not only used in conjunction with new automotive refrigerant R1234yf, but is also compatible with R134a refrigerant. The density data are converted to specific volume data.
