Fluorcarbon fishing lines are good for fishing lures that sink as fluorcarbon fishing line does sink. Because it sinks, it is not good for fishing lures that float on the surface. The fluorocarbon line will sink and you will not get good action from the topwater baits.
Tetrachloroethene is a synthetic chemical. It is a liquid at room temperature, but evaporates readily. It does not burn, but if subjected to flame will decompose into hydrogen chloride and phosgene.Synonyms for tetrachloroethene include tetrachloroethylene, perchloroethylene, perc, PCE, perclene, and perchlor. [1,3].etrachloroethene in the Environment. Humans can be exposed to tetrachloroethene from environmental, consumer product, and occupational sources. Because tetrachloroethene evaporates quickly, the most common exposure to tetrachloroethene comes from breathing air containing it.
