Teflon™ PTFE (Polytetrafluoroethylene) / Resin Information & Properties. Teflon™ PTFE is a performance thermoplastic known for its chemical inertness & resistance to attack, low coefficient of friction, broad operating temperature range, excellent dielectric properties, thermal & electrical insulating, negligible water absorption and non-stick

Whereas, Delrin is composed of polyoxymethylene. Teflon has dielectric properties and is used in electric circuits. On the flip side, Delrin is not hydrophobic and does not impact the environment negatively.

Follow the links below to view complete property information. The unique combination of properties inherent to all Teflon™ industrial coatings make them a natural choice in a number of industries. NON-STICK - Very few solid substances will permanently adhere to a Teflon ™ coating. While tacky materials may show some adhesion, almost all substances release easily. Teflon® – a polytetrafluoroethylene – has outstanding dielectric properties that remain stable 5.

The properties of PTFE include three common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare PTFE to: fluoroplastics (top), all thermoplastics (middle), and the entire database (bottom).

Teflon uppfanns av misstag 1938 av Roy J. Plunkett, anställd vid Kinetic Chemicals, ett företag som var ett samriskföretag mellan DuPont och General Motors. Egentligen forskade man på att ta fram ett nytt köldmedel ( CFC ) till kylskåp som skulle ersätta giftiga varianter som ammoniak , metylklorid och svaveldioxid .

PTFE’s density is also very high, at 2200 kg/m3.

Teflon has a high dielectric strength over many different frequencies, low dissipation factor and high surface resistivity .It can withstand high voltage before it breaks down.In addition to this teflon has a low dissipation factor; that is the percentage of electrical energy absorbed and lost when current is applied to an insulating material.
