R12 refrigeration
character and using£º
R12 is achromaticity gas in normal temp and achromaticity liquid in self press,£¬innocuity and no burn self£¬it has better stability of heating and chemistry.it don't canker with other metal without magnesium and magnesium metal.it hard dissolve water.but can dissolve with any proportion carbohydrate ,some impregnant.it is a cryogen of using expediency and safety£¬it usual use for many kinds of refrigeration for get the freeze temp.about -60- 10¡æ,and it using in flavor,medical treatment, plastic are.
