PTFE and F4B
Polytetrafluoroethylene (or PTFE), commonly known as "Plastic King", is a polymer compound formed by polymerization of tetrafluoroethylene. It has excellent chemical stability, corrosion resistance, airtightness, high lubrication and non-stick properties, Insulation and good aging resistance. Used as engineering plastics, it can be made into PTFE tubes, rods, belts, plates, films, etc. Generally used in corrosion-resistant pipelines, tanks, pumps, valves, radar, high-frequency communication equipment, radio equipment, etc. with high performance requirements.
Full English name: polytetrafluoroethylene, abbreviation: PTFE
Polytetrafluoroethylene (F4, PTFE) has a series of excellent performance: high temperature resistance-long-term use temperature of 200~260 degrees, low temperature resistance-still soft at -100 degrees; corrosion resistance-resistance to aqua regia
All organic solvents; weather resistance-the best aging life in plastics; high lubrication-the smallest coefficient of friction in plastics ((0.04); non-stickiness-the smallest surface tension in solid materials without adhesion of any substances; non-toxic -Physiologically inert; Excellent electrical properties. It is an ideal C-level insulating material. A thick layer of newspaper can block the high voltage of 1500V; it is smoother than ice.
Teflon is a trademark used by Shebang Company in a series of fluoropolymers.
In 1938, chemist Dr. Roy J. Plunkett invented polytetrafluoroethylene resin in DuPont's Jackson Laboratory in New Jersey, USA. Obtained its patent in 1941, and used the name "Teflon" as a registered trademark in 1944, and realized industrial production in 1950. In China, due to the pronunciation, the trademark "Teflon" is also called Teflon, Teflon, Teflon, Teflon, Teflon, etc., all of which are the transliteration of Teflon.
