Components for blends

The unsaturated components – CFO and HFO – now also used partly originate from plastics production processes. As they are categorised in flammability class 2, they are not used as single component refrigerant. Material compatibility has to be investigated because these substances were not used widely as refrigerants. The three listed substances do not fall under the definition of PFAS in the Registration of Intent for REACH of July 2021.
