- They are frequently used in air conditioning and as refrigerants, R-134a is one of the most commonly used HFC refrigerants.
- In order to aid the recovery of the stratospheric ozone layer, HFCs were adopted to replace the more potent chlorofluorocarbons such as R-12, which were phased out from use by the Montreal Protocol, and hydrochlorofluorocarbons such as R-21 which are presently being phased out.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Hydrofluorocarbon article was read about 25,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 52 and blocks with 28: each hit it takes is cut by 11 %.
