    產品名稱:R142b

    Properties and Applications:

    Difluorochloroethane (HcFC-142b for short), achromatism under the normal temperature, insipidity, transparent liquid in RT. Commonly be used in the refrigeration system in the high temperature, blend with HFC-22 as the foam, midway of boost of aviation. It can still be used in the temperature- control element as a medium of induction and chemical material.
