Glossary

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It is one of the most well-known and widely applied PFAS. The commonly known brand name of PTFE-based composition is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938.

In an industrial context, Teflon is a brand name for a type of fluoropolymer resin used in various applications due to its non-stick, non-reactive, and high-temperature properties. Teflon is often used in industries such as food processing, chemical manufacturing, and aerospace. Here are some examples of Teflon in different contexts:

1. Food processing: Teflon is used to coat cooking surfaces and food processing equipment to prevent sticking and make cleaning easier. Examples of Teflon-coated equipment in food processing include frying pans, baking sheets, and conveyor belts.

2. Chemical manufacturing: Teflon is used in the production of various chemicals due to its non-reactive properties. Examples of Teflon applications in chemical manufacturing include pipes, tanks, and valves.

3. Aerospace: Teflon is used in the aerospace industry due to its high-temperature resistance and non-stick properties. Examples of Teflon applications in aerospace include bearings, seals, and gaskets.

4. Electrical: Teflon is used in electrical applications due to its high dielectric strength and chemical resistance. Examples of Teflon applications in electrical equipment include wire insulation, circuit boards, and connectors.

Other terms related to Teflon in industrial contexts include:

1. Non-stick coatings: Coatings used to prevent materials from sticking to surfaces. Examples of non-stick coatings include ceramic coatings and silicone coatings.

2. Fluoropolymers: A group of polymers that contain fluorine atoms and are known for their non-stick and non-reactive properties. Examples of fluoropolymers include PTFE (Teflon), PFA, and FEP.

3. High-temperature materials: Materials that can withstand high temperatures without melting or degrading. Examples of high-temperature materials include ceramics, refractory metals, and some polymers like PTFE.

4. Chemical-resistant materials: Materials that are resistant to damage or degradation from exposure to various chemicals. Examples of chemical-resistant materials include metals such as stainless steel and plastics such as Teflon.
