[Usage]R245fa is also known as 1,1,1,3,3-Pentafluoropropane, 245fa, HFC-245fa, Pentafluoropropane, Freon 245fa. R245fa is the generation 3 blowing agent, substitute CFCs and HCFCs as blowing agent in rigid foam (PU), in refrigeration, cold house and construction. R245fa is also used as a refrigerant gas, replacing R123, R22. Now R245fa main factories in China and USA.

[packing]R245fa packing usually is 13.6kg/cylinder, 100kg/cylinder, 1000kg/cylinder and ISO TANK.
