Using hydrofluoroether solvents to replace HCFC-141b, Part II.
The use of hydrochlorofluocarbon (HFC) solvents is banned from the end of 2001. Part of this article assessed the merits of using hydrofluoroethers as replacement solvents. Alternatives to HFCs are more expensive. Part II looks at how to reduce the cost of conversion.
