Octafluorocyclobutane C4F8 5N Electronic Grade

Octafluorocyclobutane (also known as perfluorocyclobutane, C4F8, referred to as C-318) is a special fluorine-containing gas developed by DuPont in the United States in the 1950s. At normal temperature, octafluorocyclobutane is a colorless, odorless, non-flammable gas.

 

CAS NO	115-25-3
UN NO	1976
EINECS NO	204-075-2
Molecular weight	200.03
Appearance	Colorless, Odorless

In recent years, the scale of the global semiconductor industry has continued to expand, and the demand for electronic-grade octafluorocyclobutane has also continued to increase. As the size of chip manufacturing processes continues to decrease, the purity requirements for octafluorocyclobutane have become increasingly stringent. Harsh, the purity must reach 5N level or above to meet the chip production requirements.

Octafluorocyclobutane C4F8 is often used in semiconductor PECVD (Plasma Enhance. Chemical Vapor deposition) process, C4F8 is used as a substitute for CF4 or C2F6, used as cleaning gas and semiconductor process etching gas.

Octafluorocyclobutane C4F8 use as Food packaging gas:

A food additive, which is a (usually inert) gas used to encapsulate food during packaging, thereby protecting Octafluorocyclobutane C4F8 Gas from unwanted chemical reactions during subsequent transport and storage, such as food spoilage or oxidation. 

Food propellant:

Octafluorocyclobutane C4F8 used to expel food from aerosol containers.
