  2. HC-12a - Wikipedia

    en.wikipedia.org/wiki/HC-12a

    HC-12a is a mixture of hydrocarbons, specifically propane (R-290) and isobutane (R-600a), and is therefore considered nearly non-ozone-depleting. The hydrocarbon blend is compatible with hoses and oils used in R-12 systems. As it is flammable, it is illegal for use as an R-12 replacement in the United States.

  3. Compatibility (chemical) - Wikipedia

    en.wikipedia.org/wiki/Compatibility_(chemical)

    Chemical compatibility is a rough measure of how stable a substance is when mixed with another substance. [1] If two substances can mix together and not undergo a chemical reaction, they are considered compatible. Incompatible chemicals react with each other, and can cause corrosion, mechanical weakening, evolution of gas, fire, or other ...

  4. Dichlorodifluoromethane - Wikipedia

    en.wikipedia.org/wiki/Dichlorodifluoromethane

    Mineral oil used with R-12 is not compatible with R-134a. Some oils designed for conversion to R-134a are advertised as compatible with residual R-12 mineral oil. Illegal replacements for R-12 include highly flammable hydrocarbon blends such as HC-12a, the flammability of which has caused injuries and deaths. [10] [11]

  5. 1,1,1,2-Tetrafluoroethane - Wikipedia

    en.wikipedia.org/wiki/1,1,1,2-Tetrafluoroethane

    1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...

  7. Polyolester - Wikipedia

    en.wikipedia.org/wiki/Polyolester

    Polyolester oil (POE oil) is a type of wax-free synthetic oils used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A, and R-12. [1] POE oils are used as a lubricant in systems using the refrigerant HFC-134a when replacing CFC-12, as these systems traditionally use mineral oil, [2] which HFC-134a does not mix ...

  8. Surfactants in paint - Wikipedia

    en.wikipedia.org/wiki/Surfactants_in_paint

    The solvent also modifies the curing rate and viscosity of the paint in its liquid state. There are two types of paint: solvent-borne and water-borne paints. Solvent-borne paints use organic solvents as the primary vehicle carrying the solid components in a paint formulation, whereas water-borne paints use water as the continuous medium.

  9. R-407C - Wikipedia

    en.wikipedia.org/wiki/R-407C

    It is a zeotropic blend of difluoromethane (R-32), pentafluoroethane (R-125), and 1,1,1,2-tetrafluoroethane (R-134a). Difluoromethane serves to provide the heat capacity, pentafluoroethane decreases flammability, tetrafluoroethane reduces pressure. [1] R-407C cylinders are colored burnt orange.
