Specification of Gasket Teflon PTFE

Teflon PTFE is a polytetrafluoroethylene (PTFE) derived from a solid fluorocarbon base material, because the molecular weight of the compound consists entirely of carbon and fluorine. Teflon molecular structure is a long chain of carbon atoms, similar to other polymers. This long chain of atoms is surrounded by fluorine atoms. The bond between the carbon and fluorine atoms is very strong.

CarbonTeflon PTFE is present in all living things and is the basis of organic chemistry. This element is also unique in its ability to form chemical bonds with fellow carbon and many other types of elements, forming nearly 10 million known types of compounds. This element is the most stable element among the other elements.

Fluorine is the most electronegative and reactive element when compared to all elements. Pale yellow, corrosive gas, which reacts with many organic and inorganic compounds, such as metals, glass, ceramics, carbon, even water burns in fluorine with a bright flame. Fluorine is so reactive that it is rarely found free, fluorine is found to bind to other elements or compounds.

In the process of making Teflon another chemical called Perfluorooctanoic acid (PFOA or C8) is used which is an ammonia salt. This substance is used as a surfactant in PTFE polymer emulsions. Therefore chemicals in the non-stick coating contain various harmful metals such as mercury and carcinogenic PFOA substances.

Teflon is also a very strong synthetic material, generally white in color. Teflon is resistant to heat up to about 250 ° C, and above 250 ° C the Teflon begins to soften, in the fire it will melt and it becomes difficult to make charcoal. The specific gravity is about 2.2 g / cmI. Teflon is not resistant to alkaline hydroxide solutions. Also less resistant to hydrocarbons containing chlorine.
