The Main Properties of PTFE Other useful PTFE properties are its high flexural strength, even in low temperatures, high electrical resistance and dielectric strength, resistance to water (owing to fluorine's high electronegativity), and low coefficient of friction. PTFE's density is also very high, at 2200 kg/m3.
The simple answer is that they are the same thing: Teflon™ is a brand name for PTFE (Polytetrafluoroethylene) and is a trademark brand name used by the Du Pont company and its subsidiary companies (Kinetic which first registered the trademark & Chemours which currently owns it).
It is a safe and non-toxic substance when used as intended. PTFE is stable and non-reactive, and does not break down into harmful chemicals when heated to normal cooking temperatures. However, if PTFE is heated to very high temperatures, it can release fumes that may cause flu-like symptoms in humans.
The main disadvantage of PTFE is that it does not actually melt when heated and is therefore difficult to process. Very unconventional techniques are needed to mould, extrude and weld this fluoropolymer.
Nonstick cookware coated with PTFE is safe to use. Delicate food cooked at lower temperatures comes out better using nonstick cookware. Proper care and storage will prolong the lifespan of your PTFE-coated cookware
PTFE is a high-performance material that is more expensive than other materials commonly used for PCB substrates, such as FR-4. In addition to the cost of the material, the specialized manufacturing processes required for PTFE PCBs also contribute to their higher cost
Polytetrafluoroethylene (PTFE) is a fluoropolymer and is commonly known by its trade name, Teflon®. Unique properties of PTFE include nonreactivity, hydrophobicity, a low coefficient of friction, and good insulating properties. It is most commonly used as a nonstick coating for cookware.
PTFE Sheet is offered in standard width of 1000 mm in thickness from 0.2 mm to 6 mm for skived sheet and 5 mm to 100 mm in 1000 x 1000 sqmm for moulded sheet.
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of applications, though it's perhaps best-known for its non-stick properties.
Essentially, the only difference lies in the name. PTFE is the shortened name of the chemical polytetrafluoroethylene, and Teflon is the trade name of the same polymer. If you are looking for a highly flexible, non-stick material that is chemical, electrical and thermal resistant, look no further than PTFE.
