Propellant R141b

HCFC-141b  

● Property Uses  

is a colorless transparent liquid at room temperature, non-toxic, low ODP, and has good chemical stability. Because of its similar physical properties to CFC-11 and CFC-113, CFC-11 can be used as a foaming agent for rigid and soft polyester foams, or as a metal cleaning agent or defluxing agent instead of CFC-113. HCFC-141b has the following characteristics:  
1. Chemical stability: storage at room temperature, stable performance, no decomposition. 
2, soluble in most organic solvents, alcohols and ethers, good compatibility with greases and lubricants, but has no obvious effect on most plastics such as plastics and rubber. 
3. HCFC-141b has no stimulating effect on human skin and eye mucosa, but when inhaled high concentration of HCFC-141b, it will produce anesthesia.
