Refrigerant HCFC-141B : :

Description
R141B products belong to HCFC series refrigerant. It is colorless liquid under ordinary temperatures. Non-toxicity, low ODP and good chemical stability is R141b? character, which is similar with R11 and R113, so it can be used to replace the R11 as the foamer of plastic, and replace R113 as a cleaner.
