  • Applications

    1,1,1,3,3,3-Hexafluoropropane (CAS 690-39-1) is used as a specialty solvent for high-purity cleaning and formulation in electronics and precision manufacturing; it can serve as a solvent or carrier in coatings, inks, and adhesive formulations; it may act as an intermediate or building block in the synthesis of fluorinated polymers and related materials; it is evaluated as a heat-transfer fluid or coolant for closed-loop equipment; it is also used as a processing aid or blowing agent in polymer foams and surface coatings; and in some niche applications it may be considered as a refrigerant or alternative working fluid, subject to regulatory constraints.
