Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] The commonly known brand name of PTFE-based composition is Teflon by Chemours , [ 4 ] a spin-off from DuPont , which originally invented the compound in 1938. [ 4 ]
Teflon: Polytetrafluoroethylene (PTFE) Very low coefficient of friction, excellent dielectric properties, high melting, chemically inert: Plain bearings, gears, non-stick pans, etc. due to its low friction. Used as a tubing for highly corrosive chemicals. Ultem: Polyimide: Heat,flame and solvent resistant. Has high dielectric strength
Other examples of ingredient branding include: NutraSweet and Canderel, a brand name for the artificial sweetener Aspartame in the food industry (Coca-Cola lite) Teflon as a coating for pots and pans and Gore-Tex for sportswear (both products are brand names for polytetrafluoroethylene) Makrolon, a plastic produced by Bayer MaterialScience
In 1938, polytetrafluoroethylene (DuPont brand name Teflon) was discovered by accident by a recently hired DuPont Ph.D., Roy J. Plunkett. While working with tetrafluoroethylene gas to develop refrigerants, he noticed that a previously pressurized cylinder had no pressure remaining. In dissecting the cylinder, he found a mass of white solid in a ...
Advocates have been asking the FDA for nearly two decades to require front-of-pack labels, which they say help people make healthier choices and prod food manufacturers to reformulate their ...
A new rule from the Food and Drug Administration (FDA) will update what it means for food to be labeled “healthy” for the first time in 30 years, a move that aligns with current nutrition ...
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer used in various applications including non-stick coatings. Teflon is a brand of PTFE, often used as a generic term for PTFE. The metallic substrate is roughened by abrasive blasting, then sometimes electric-arc sprayed with stainless steel.
But buzz is building around so-called "Teflon flu" after a growing number of people have reported getting sick from using pans coated with polytetrafluoroethylene (PTFE), aka Teflon.
