Properties and Applications:

Difluoroethane (HFC -152a for short), achromatism under the normal temperature, insipidity, flammability and explosive transparent liquid in RT, mostly used in the replacement of (R12) and (R114)and(R 134a ). It is usually used as a cryogen, inhalator boost and the raw material for fluorin chemicals.
