Teflon O rings, a trademark of polytetrafluoroethylene (PTFE O-ring) is a chemical compound that was discovered in 1938 by Roy Plunkett in the Jackson Laboratory of the firm Dupont in the American state New Jersey.
At the time Plunkett applied for a patent on this substance, which was granted on 4 February 1941. Later in 1949 Teflon® was introduced as a commercial product.
Teflon® is often referred to as a spin-off of the American space program even though this material was brought to the market before this. The assumption that the spin-off originated from the Manhattan project is more likely.
The Manhattan project was the name of the very secret operation, led by the United States, with the help of Canada and the United Kingdom. With this project, the United States was able to develop the atomic bomb during the Second World War.
After the American Food and Drug Administration (FDA) did its research on Teflon®, it was approved for use in food preparation.
What is a PTFE Teflon® Oring?
Teflon is an ethylene polymer in which all hydrogen atoms are replaced by fluorine. The polymer has a very large length and is still one of the largest molecules. PTFE is a thermoplastic; however, it cannot be processed in a thermoplastic manner. PTFE is pressed as a powder at room temperature in a mold and then sintered in an oven.

Polytetrafluoroethylene (PTFE)
MATERIAL DESCRIPTION:
Polytetrafluoroethylene (PTFE) is a high molecular weight polymer, one of the most versatile plastic materials known and useful for a large range of products for applications excluded to other materials.
PTFE is generally considered a thermoplastic polymer; at 327°C (620.6°F) it retains a very high viscosity, thus requiring particular transformation techniques for manufacturing of finished and semi‐finished goods. PTFE can be used in a temperature range from ‐200°C (‐328°F) to +260°C (500°F).
OUTSTANDING CHARACTERISTICS:
THERMAL PROPERTIES:
PTFE is one of the most thermally stable plastic materials. There is no appreciable decomposition at 260°C (500°F), so that PTFE, at this temperature, still possesses the greater part of its properties. Appreciable decomposition begins at over 400°C (932°F). The coefficient of the thermal conductivity of PTFE does not vary with the temperature. It is relatively high, so that PTFE can be considered to be a good insulating material. The mixing of suitable fillers improves the thermal conductivity.
