Dichlorofluoroethane (HCFC-141b) is a non-toxic and colorless chemical with small ODP value and excellent chemical stability.Since its physical and chemical properties are similar to those of CFC-11 and CFC-113, it can substitute CFC-11 as foaming agent for rigid or soft PU foam without changing process and equipment, or CFC-113 as metal cleaner and solder-remover as well.
