Third, Uses
Hexafluoropropylene is one of the important monomers of organic fluorine materials. It has high chemical activity and can carry out various types of chemical reactions. It is a raw material for preparing a variety of fluorine-containing fine chemical products, pharmaceutical intermediates, fire extinguishing agents, etc. This product is copolymerized with other olefins to produce fluoropolymer materials.
Fourth, the packaging specifications:
800kg/800L, 1000kg/1000L steel cylinder or transport tank
Fifth, note:
The filling factor of the hexafluoropropylene cylinder is 1.06kg/L. After the cylinder valve is closed, the head and the cylinder cap are tightly closed to prevent leakage;
Violent vibration should be avoided during the transportation of cylinders. The cylinders should be placed in a ventilated, dry, safe place and away from heat sources;
Hexafluoropropylene is a Class III toxic substance and avoids direct inhalation.
