C318 (Octafluorocyclobutane, C4F8, RC318, perfluorocyclobutane) is a colorless, odorless, transparent and incombustible liquefied gas with stable chemical properties.
boiling point: -5.85 ℃, melting point: -41.4 ℃, liquid density (25 ℃ ): 1.62g / cm3.
Applications：It is mainly used as an propellants in food industry, refrigerants, etchant in integrated circuits, and semiconductors productions. It also can be mixed with sulfur hexafluoride to use as dielectri medium and medium for the polymerization of fluorine-containing compounds.
Packing: It is filled with steel cylinder, tontank or ISOTANK
After closing the cylinder valve, close the bulkhead and cylinder cap to prevent leakage. Shock should be avoided during the transportation of steel cylinders. Steel cylinders should be stacked in a ventilated, dry and safe place and away from heat sources. When the concentration of the product reaches to reduce the oxygen content in the air to less than 19.5%, it will cause suffocation; rescuers must wear self-contained breathing apparatus; contact with the product will cause frostbite
