1.Properties and Applications:
is a colorless and transparent liquid at room temperature.It has low ODP value and excellent chemical stability.Since its physical and chemical properties are similar to those of CFC-11,CFC-113,it can substitute CFC-11 as foaming agent for rigid or soft PU foam ,or CFC-113 as metal cleaner and solder -remover as well.
It has following characteristics:
1).Chemical Stability: It is stable while stored at roon temperature and will not decompose.
2).It can dissolve in most organic solvents, alcohol and ether.It has excellent compatibiity with grease and lubricant ,and no abvious effects on most polymers including plastic an rubbers.
3).HCFC-141b is not irritate to human skin and eyes ,but inhale HCFC-141b of high concetration eill cause anesthesia.
4).HCFC-141b is flammble ,and should be stored in well-ventilated place without flame.
