Polyurethane Spray HCFC-R141B Used for Prouduce Urethane Foam

Properties: Dichlorofluoroethane (HCFC-141B) is a no-toxic and colorless chemical   with low ODP value and excellent chemical stability. Since its physical and   chemical properties are similar to those CFC-11 and CFC-113, it can replace   CFC-11 as foaming agent for rigid or soft PU foam, or it can be a substitute   for CFC-113 as metal cleaner and solder remover as well, it’s a worldwide   acknowledged CFCs substitute.

Application:

1)       Used as foaming Agent for polyurethane spray

2)       Used for polyurethane foam

3)       Used to produce urethane foam

4)       Used for expanding polyurethane foam

Package and   Storage: Packed   in iron drum, It should be stored in cool, dry and ventilated place, and kept   away from sunlight and rain.

Characteristics:

1. Chemical Stability: It can be stored at normal   temperature without decomposition.

2.Corrosion: Even being boiled, it does not corrode   iron, stainless steel, copper. Brass, aluminum and zine etc.

3. Solubility: It is soluble in most organic solvents,   alcohol and ether, it has excellent compatibility with grease and lubricant,   has no obvious in effects on most polymers including plastics and rubbers.

4. Toxicty: The toxicity trials conducted by the   international society PATT II indicates that is has on irritant effect on   human skin and eyes, but inhalation of high-concentrated HCFC-141B will cause   anaesthetic effect
