Whether or not a hazardous chemical: no

R152a and other components of mixed refrigerant refrigerant, widely used in refrigeration system, should use R152a good safety measures should be used exclusively for the R152a detector, with mixed refrigerant, the original halogen leak detector must be calibrated. R152a is used as the main raw material for foaming, aerosol, cleaning and polyvinylidene fluoride.

Chemical name: 1,1- two fluoroethane

Molecular formula: CH3CHF2

The ODP value of R152a is zero, and the GWP is only very small, 0.023. Although the latter is much lower than R134a, it is still not zero, and there is a direct greenhouse effect.

The standard boiling point of R152a is -25 C, and the freezing point is -117 C, which is better than R12 in the refrigeration cycle.

R152a has higher unit volume refrigeration capacity and energy efficiency ratio than R12 and R134a.

The viscosity of R152a is not very different from that of R12, but the specific heat capacity and gasification latent heat of liquid and gas are larger than that of R12, and the thermal conductivity of gas and liquid is significantly higher than that of R12.

.

R152a has flammability, and when the volume fraction of the air reaches 4~17%, it will catch fire.
