A fundamental and important property of polytetrafluoroethylene (PTFE) and other fluoropolymers is their resistance to organic and inorganic chemicals. Chemical properties of PTFE are not affected by fabrication conditions. Another aspect of the interaction of this plastic with chemicals is permeation. ...

Alkaline earth metals, like calcium and barium, are very likely to form ionic compounds after reacting with nonmetals like oxygen, fluorine, and sulfur that have high electronegativities. This results in a melt and boiling point higher than the norm because of the strong ionic bonds which exist...
(5 to 40%) and different flow rates (700 to 1,100 L/h). At 20% excess oxygen and a flow rate of 860 L/h, the amount of fluorine emitted ranged from 850.7 ng/kg at 950 °C to 3,632.8 ng/kg at 750 °C. The greatest amount of PAHs emitted were observed at 750 °C (...
A second chemical property of alkanes is halogenation. Halogenation is a chemical reaction used to add a halogen to a compound. Halogens consist of five elements that are chemically related to one another: fluorine, chlorine, bromine, iodine, and astatine. Lesson...
2.3Property Clustering Technique in Reverse Problem Formulation Since the properties of a chemical compound or mixture affect the usefulness of a product, a property based solution approach would seem to be most appropriate. The property clustering technique is a property-based visualization tool that ...
