Polytetrafluoroethylene: Applications, Properties and Manufacture

Polytetrafluoroethylene is made of different materials. It is slippery, non-stick, and has excellent chemical stability. It is resistant to all kinds of corrosion and can be stabilized at high temperatures.

As far as its application is concerned, it is often lined in chemical equipment to protect the body from corrosion. The surface of the cooker is covered, the food does not stick, and it is convenient to cook. In the field of electronics, because of its good insulation, it is the best choice for circuit boards and cables. In aerospace, it is also used for key components due to its characteristics.

In terms of its properties, its extremely low coefficient of friction is comparable to almost nothing. Acid-resistant and alkali-resistant, not afraid of the erosion of strong acids and alkalis. Heat-resistant and cold-resistant, refractory at high temperatures, and not brittle at low temperatures.

As for the manufacturing method, first polymerize with TFE monomer, and carefully adjust the reaction conditions, such as temperature, pressure, and catalyst, to obtain polytetrafluoroethylene. After polymerization, it is re-formed, molded, or extruded, and finally becomes a usable material. With its outstanding properties, this material shines in many fields and is an indispensable material in the world.
