Non-stick pan coating is a chemical material, also called polytetrafluoroethylene, with resistance to acid and alkali, resistant to various organic solvents. Specifically introduced as follows:
1, English name: PTFE (Polytetrafluoroethylene)
2, Chinese name: polytetrafluoroethylene
3, Chinese aliases: PTFE; Teflon; Teflon; teflon; Teflon; 4F; plastics
4, English name: Polytetrafluoroethylene (abbreviated as Teflon or [PTFE, F4])
5, Molecular Formula: (C2F4)n
6, Chemical Formula: -(CF2-CF2)n-
7, Molecular Weight of Monomer: 100.015612(C2F4)
8 Melting point: 327℃
9, Performance:
Nonstick coating is one of the corrosion-resistant materials in the world today, except for molten alkali metals, chlorine trifluoride, chlorine pentafluoride and liquid fluorine, it can resist all other chemicals, and it doesn't change by boiling in aqua regia, so it is widely used in a variety of occasions that require resistance to acids, alkalis and organic solvents.
It also possesses sealing, high lubrication and non-stickiness, electric insulation and good anti-aging ability, excellent temperature resistance (can work for a long time under the temperature from positive 250℃ to negative 180℃), and its itself has no toxicity to human beings.
10, Application:
Polytetrafluoroethylene can be molded by compression or extrusion process; it can also be made into aqueous dispersions for coating, impregnation or made into fibers.
Polytetrafluoroethylene in atomic energy, national defense, aerospace, electronics, electrical, chemical, mechanical, instrumentation, instrumentation, construction, textile, metal surface treatment, system, medical, textile, food, metallurgy and smelting and other industries are widely used as high and low temperature resistance, corrosion-resistant materials, insulating materials, anti-adhesive coatings and so on, so that it has become an irreplaceable product.
