Refrigerant R134a For Automobile A/C
R134aR134a is internationally recognized as one of the main refrigerant working substances to substitute CFC-12. It does not contain chlorine atom, gives no bad effects against ozonosphere and has excellent safety performances, such as non-toxicity, non-inflammability, non-explosive ability , non-pungency, and non-corrosive ability. It is a colorless gas under ordinary temperature and a colorless & transparent liquid under the pressure of itself. As the substitute for CFC-12, it is often used in the refrigerating systems of auto air conditioners, commercial and industrial purposes, and as the vesicant, it is used to produce the heat-protective material made of rigid plastics, and also to prepare other blend refrigerants, such as R404A & R407C.Properties：IndexUnit(R134a)Chemical formulaCH2FCF3Molecular weightg/mol102.0Boiling point 101.3KPa (℃)℃-26.2Freezing point 101.3KPa (℃)℃-96.6Critical temperature℃101.1Critical pressureKPa4066.6Saturated liquid density (25℃)Kg/m31188.1Specific heat (25℃liquid)KJ/kg.k1.42Critical densityg/cm30.512Vaporization heat at boiling pointKJ/kg215.0Water solubility (25℃)W%0.15ODP0GWP0.29Quality Specification：IndexExcellent GradeGrade IAppearanceColorless &transparent liquidPurity % ≥99.999.5Moisture % ≤0.0010.005Acidity (as HCl) % ≤0.00010.0001Evaporation residue % ≤0.010.01Chlorides(Cl-) test % ≤0.0003No condensable gas (V/V) % ≤1.0Packing：13.6kg, 800kg/L, 950kg/926L steel cylinders.PS：HS Code 29033090.90.
