Carbon Teflon - What Are the Different Types of Carbon PTFE?

Carbon PTFE (also known as Teflon) is used for a wide variety of applications due to its unique properties. It is chemically inert, has a high resistance to water and most corrosives, and has excellent non-stick qualities.

It is also able to resist huge temperature changes. This is why it is often used in the aerospace industry, as well as for food and drink manufacturing, pharmaceuticals and telecommunications.

However, its heat resistance is not perfect and can be damaged by overheating. It can also be poisonous to birds, especially pet birds, as it breaks down into hydrogen fluoride and carbon monoxide when heated over 280degC.

The best way to prevent PTFE poisoning is to avoid contact with it in the first place and not use it on hot surfaces. Another great way to reduce PTFE poisoning is to avoid using it in a seal or ring for reciprocating compressors.

Carbon-Filled PTFE is a combination of virgin PTFE and carbon, which provides increased wear resistance and deformation properties over that of a pure material. The addition of carbon improves the abrasion resistance of PTFE and increases the thermal conductivity.

Fillers for PTFE

The addition of bronze, stainless steel and graphite fillers improves the abrasion resistance and deformation properties of PTFE. The addition of these fillers also enhances the electrical conductivity of PTFE. These fillers can be added in the form of powder or fiber.

Generally, the ratio of the PTFE to the filler should be 25-60% of PTFE. The addition of the filler also improves the mechanical strength, compressive resistance and elasticity of the material.
