CELEFIN® 1233Z Background of development and characteristics

Stronger regulation on these products are driving demand for new products with both zero-ODP and low GWP. In the area of fluorine-based solvents and cleaning agents, CFC-113 or HCFC-225, which have a high ozone depletion potential (ODP) were used. Currently, HFCs and HFEs, which have a high global warming potential (GWP), are being used.
Other than fluorine-based, highly toxic brominated agents (such as 1-bromopropane) and flammable hydrocarbons are used, and there is a growing demand for products that meet safety requirements (low toxicity and nonflammability) while maintaining cleaning performance.
Under these conditions, Central Glass has developed CELEFIN® 1233Z (HFO-1233zd (Z)), a fluorine-based solvent that satisfies all of the requirements of environmental performance, cleaning performance, safety, and easy handling.
