R508B REFRIGERANT

R508B Near-azeotropic Blend Refrigerant

Alias: R508B, R23/R116 blend | Formula: R23 / R116 (46/54) | CAS: —

R508B is a near-azeotropic blend of R23 and R116 (46/54) with a boiling point around -106℃. Designed for ultra-low-temperature cascade systems below -80℃, it is an environmentally friendlier replacement for phased-out R13.
