Carrier for fluorine lubricating oils
solvents and dispersion media
thermally conductive liquid
insulation fluid
Can replace a variety of fluorine liquids such as R141b, PFC, R113, etc.
Safety/flammability
SF33 is a non-flammable liquid and will not become a flammable substance during boiling and evaporation. They are also not flammable liquids in the open and closed NATT and DOT classifications. Its thermal stability is higher than that in the cup test and there is no flash point. At 250℃.
storage and disposal
R1336mzz has good thermal stability. It does not oxidize and will not degrade during storage. Store in a cool, clean and dry area. Prevent leaks and potential contamination.
The boiling point of R1336mzz is only 33 degrees, so the product should be stored at a low ambient temperature, below the boiling point, to avoid pressure on the packaging drum.
Packaging specifications:
23kg/barrel, 230kg/barrel.
Application areas
Grouped by equipment type, for selection reference only; the equipment manufacturer's requirements and local regulations prevail.
