| melting point,ºC | -136 | boiling point evaporation potential,KJ/Kg | 390.5 |
| density(25ºC) liquid, g/cm³ | 0.960 | vapour pressure(25ºC),Mpa | 1.702 |
| critical temperature,ºC | 78.52 | critical pressure,Mpa | 5.808 |

| ODP | 0 | GWP | 0.11 |
Quality index(Q/320623 NTD 01-2012):
| purity,% | ≥99.8 |
| moisture,% | ≤0.001 |
| acidity,% | ≤0.0001 |
| evaporated residue,% | ≤ 0.01 |
| chloride (cl-)experiment | test permition |
| noncondensable gas(v/v),% | 1.5 |

Packing specification: 7kg,670Kg/926L, 30Kg/40L steel cyinder
Uses: as refrigerating fluid
Our Advantages over other factories in the production of refrigerant gas
We are the supplier of many big air conditioner and commerical condioning customers.
The cylinders have CE/DOT/KGS certificate
New technology cylinder, 100% safety no leakage
We have our own labs to guarantee the gas purity 99.91%-99.97%
R134A gas has REACH certificate
We have R32,R152,R22,R134A,R410A,R407C,R404A…
Through comparative analysis of experimental results, it is found that R32 is relatively safe in terms of flammability and is difficult to burn unless it encounters an open flame. Even if the internal components of the air conditioner fail to cause local overheating, it is difficult to burn or explode. Moreover, the price of R32 is lower than that of R410A, and the air-conditioning displacement using R32 is smaller. Therefore, R32 has broad application prospects in the air-conditioning manufacturing industry. With the development of the air-conditioning manufacturing industry, R410A and R22 will gradually be replaced by R32.
