R32 refrigerant's chemical name is difluoromethane, and its molecular formula is CH2F2. Difluoromethane is a refrigerant with zero ozone depletion potential. It is a gas at room temperature and a colorless transparent liquid under its own pressure. It is easily soluble in oil but difficult to dissolve in water.

R32 refrigerant is used as a special refrigerant or a raw material for mixed refrigerants such as R407/R410/R504.

Refrigerant cylinders are pressurized containers and should be stored away from fire and heat sources and avoid direct sunlight. They are usually stored in a cool, dry and ventilated warehouse.They should be loaded and unloaded gently during transportation to prevent damage to the cylinders and accessories such as valves.
