Why PTFE Is Becoming More And More Popular In Electric Heaters

PTFE polytetrafluoroethylene is known as the "King of Plastics" and is a representative product of fluorocarbon polymers. PTFE has a chemical structure in which each hydrogen atom of polyethylene is completely replaced by a fluorine atom. It is a polymer long-chain structure with a molecular weight of 2 million to 10 million. Because the fluorine atoms in fluorocarbon polymers have a strong chemical bonding force, they have better heat resistance and chemical resistance than other similar plastics. The more fluorine atoms contained in the molecule, the more significant this property is.

Advantages of PTFE materials:

Heat resistance

PTFE can be used continuously at temperatures up to 260°C, and the temperature allowed for a short period of time is higher. It also has strong low temperature resistance. Therefore, electrical and electronic components, insulated wires, etc. made of PTFE dispersions are widely used.

Chemical properties

PTFE has excellent drug resistance to commonly used chemical drugs. For general acid and alkaline oxidants, its drug resistance is still good even at high temperatures, and it will not dissolve when in contact with organic compounds.

Electrical properties

The molecular structure of PTFE is non-polar, so it is most suitable for high-frequency insulation materials. PTFE material not only has a wide temperature range, but also has a small and stable dielectric constant and dielectric loss within a fairly wide frequency range.

Corrosion resistance

In general, PTFE has a very low solid friction coefficient and will not creep. In addition, it has good non-stickiness and will hardly adhere to any material.

Therefore, PTFE material has a wide range of uses, especially in the electric heater industry, where it is becoming more and more popular. It has excellent heat resistance, insulation, and corrosion resistance. It is a high-quality material for electric heaters.
