Teflon is not a brand of down jackets, it is a coating of down jackets.
Teflon is a registered trademark used by DuPont on a series of fluoropolymer products. Chemist Dr. Roy Plunkett invented polytetrafluoroethylene at DuPont's Jackson Laboratory in New Jersey, USA. Vinyl resin, DuPont uses "Teflon" as the brand name of this product. In China, due to the pronunciation, the trademark "Teflon" is also called Teflon, Teflon, Teflon, Teflon, Teflon, etc., all of which are transliterations of Teflon.
Subsequently, DuPont developed a series of products in addition to Teflon polytetrafluoroethylene resin, including TeflonAF (amorphous fluoropolymer), TeflonFEP (fluorinated ethylene propylene resin), TeflonFFR (fluoropolymer) foam resin), TeflonNXT (fluoropolymer resin), TeflonPFA (perfluoroalkoxy resin), etc.
Characteristics of PTFE fluoropolymer
1. Non-stickiness: Almost all substances do not adhere to the PTFE coating film. Very thin films also show very good non-stick properties.
2. Heat resistance: PTFE coating has excellent heat resistance and low temperature resistance. It can withstand high temperatures up to 300°C in a short period of time, and can generally be used continuously between 240°C and 260°C. It has significant thermal stability. It can work at freezing temperatures without brittleness, and without melting at high temperatures.
3. Sliding property: PTFE coating has a low friction coefficient. The friction coefficient changes when the load slides, but the value is only between 0.05-0.15.
4. Moisture resistance: The surface of the polytetrafluoroethylene coating does not stick to water and oil, and it is not easy to stick to solutions during production operations. If there is a small amount of dirt, it can be removed by simply wiping it. Short downtime, saving man-hours and improving work efficiency.
5. Wear resistance: Excellent wear resistance under high load. Under a certain load, it has the dual advantages of wear resistance and non-adhesion.
6. Corrosion resistance: PTFE is almost not corroded by chemicals and can protect parts from any kind of chemical corrosion.
