HCFC-142b
Function Description£º
It can replace CFC-12 (CFC-11)
Brief Introduction£º
It is mainly used to replace CFC-11 (CFC-12) to produce polyurethane in industry and business refrigerant line. And it is used as refrigerant in hot pump. In steel works, it is used to substitute for CFC-12 as refrigerant in air-conditioner in hot workroom.
