R-404A _____ SDS: R-404A Page 3 of 8 Current Issue Date: April 2018 UNUSUAL FIRE AND EXPLOSION HAZARDS: R-404A is not flammable at ambient temperatures and atmospheric pressure. However, this material will become combustible when mixed with air under pressure and exposed to strong ignition sources.

制冷剂r404a是新装制冷设备上替代 氟利昂 r22 和 r502 的最普遍的工业标准制冷剂（通常为低温冷冻系统），r404a最接近于r-502的运作，它适用于所有r-502可正常运作的环境，r404a得到全球绝大多数的制冷 设备制造商 的认可和使用。但是由于r404a与r502和r22物化性能 ...

Refrigerant Gas R404A is a blend of CF3CHF2 (R-125, 44% by mass), CF3CH3 (R-143A, 52%) and CH2FCF3 (R-134A, 4%). Non-combustible, but toxic gases can be produced by thermal decomposition in a fire.

R404A由R125、R134a和R143a混合而成，主要用于低中温制冷系统。 重复充装钢瓶：400L、800L、926L钢瓶及槽车。

R-404A is a ternary mixture consisting of R-125, R-143a and R-134a. Their thermodynamic characteristics constitute as ideal replacement for R-502 for refrigeration sector in new facilities at low and medium temperatures. R-404A is characterized by a remarkable chemical stability and low glide temperature 0.7 ° C. Its classification is A1 group L1.

Freon™ 404A (R-404A) is a blended hydrofluorocarbon (HFC) refrigerant comprised of R-125, R-134a, and R-143a. It was designed to replace R-502 and R-22 used in commercial refrigerator equipment for low and medium temperature ranges. Its properties make it ideal for use in display cases, refrigerated vehicles, ice makers, and other applications.
