What is the difference between TFE and PTFE?

What is TFE (tetrafluoroethylene):

Chemical formula: C2F4

TFE is an odorless and colorless gas. It is non-toxic, insoluble in most organic solvents, but is soluble in some water.

It is an important organic chemical raw material, mainly used in the production of polytetrafluoroethylene (PTFE), tetrafluoroethylene-ethylene copolymer (ETFE) and perfluoroalkane sulfonate (telomer).

TFE is highly explosive and flammable at room temperature. It must be handled and stored with care.

What is PTFE (polyteflon),

Chemical formula (C2F4)

PTFE is made by polymerizing TFE monomer.

It is a high-quality material with excellent properties. These include its resistance to heat (long-term temperature use up to 260 degrees C), its resistance to low temperatures (can maintain mechanical strength down at -196 degrees C), and its resistance against corrosion (almost unsoluble in organic solvents; can resist corrosion by strong acids, alkalis, strong oxidants etc.). It has excellent properties, such as high temperature resistance (long-term use temperature up to 260 deg C), low temperature resistance (can maintain a certain mechanical strength at -196 deg C), corrosion resistant (almost insoluble in all organic solvents, can resist the corrosion of strong acids, alkalis, strong oxidants, etc.


TFE (tetrafluoroethylene) features:

Chemically stable and not easily reactive with other substances

It is a colorless, insoluble gas at room temperature and pressure.

PTFE (teflon) features:

Temperature resistance: Long-term usage temperature can reach up to 200-260 degrees.

It is resistant to low temperatures: it can be soft even at -100 degrees.

Resistance to corrosion: Resistant to aqua regia, organic solvents and other corrosion-causing agents.

Plastics that are resistant to weather have the longest lifespan.

Small dielectric constant: excellent electrical performance. Can be used as electrical and electronic insulation.

Self-lubricating surface: Surface that is difficult to adhere to other substances.

It has a very low coefficient of friction, making it ideal for cleaning the inner layer of pipes.

TFE and PTFE applications

TFE (tetrafluoroethylene) :

This raw material is mainly used to produce PTFE and polymer materials.

The raw material is also used to manufacture new heat resistant plastics, engineering materials, new fire extinguishing and fogging agents.

PTFE (Polyteflon ):

It is used widely in many fields because of its unique properties.

PTFE materials are widely used for corrosion protection in the textile, petroleum and other industries. This is especially true in harsh environments such as low temperatures and anti-adhesion, where conventional materials can’t be used.

PTFE is a dielectric material with a low dielectric constant. It can be used in the preparation of enamelled wires that are used for micromotors. PTFE glass-laquered cloth and glasscloth can also be used as high-temperature and high-frequency insulation materials. PTFE films can be used for capacitors, etc.

PTFE is a biocompatible material that can be used to create artificial organs, such as artificial heart valves and artificial blood vessels.

PTFE can also be found in other areas such as non-stick pans, lubricants and sealing parts, cable insulation, etc.
