Polychloro-trifluoroethylene

Fluorolube . [OxyGiem] Polychloro-trifluoroethylene lubricating grease. 

Heat capacity (specific heat) n. The amount of heat required to raise the temperature of a unit mass of a substance one degree. In the SI system, the unit of heat capacity is J/kgK, but kJ/kgK, or J/gK are often more convenient. Conversions from older units are 1 cal/g°C = 1 Btu/lb°F = 4.186 J/ gK. Most neat resins have heat capacities (averaged from room temperature to about 100°C) between 0.92J/gK for polychloro-trifluoroethylene and 2.9 for polyolefins (The heat capacity of water, one of the highest of all materials, is 4.18J/gK at room temperature.) A term loosely used as a synonymous with heat capacity but not truly so is specific heat. 

The resistance of polyfvinylidene fluoride) to solvents and chemicals is generally good but inferior to that of polytetrafluoroethylene and polychloro-trifluoroethylene. Some highly polar solvents such as dimethylacetamide dissolve the polymer at elevated temperature whilst organic amines cause discoloration and embrittlement. Fuming sulphuric acid leads to sulphon-ation.
