[Usage]R32 is also called HFC-32, Freon 32, Difluoromethane. It usually mix with 125 @50:50 to get R410A. As a refrigerant difluoromethane is classified as A2L-slightly flammable. After technology updating, now pure R32 is also used for airconditioner directly, replacing R22 for home.

[packing]R32 usually has two cylinder packing: 670Kg/926L cylinder, 30Kg/40L cylinder.And now also has 30lb cylinder packing.
