PTFE is widely used as a non-stick coating for food processing equipment; [71] dough hoppers, mixing bowls, conveyor systems, rollers, and chutes. PTFE can also be reinforced where abrasion is present – for equipment processing seeded or grainy dough for example. [71] PTFE has been experimented with for electroless nickel plating.
Not all non-stick pans use Teflon; other non-stick coatings have become available. For example, a mixture of titanium and ceramic can be sandblasted onto the pan surface, and then fired at 2,000 °C (3,630 °F) to produce a non-stick ceramic coating. [19] Ceramic nonstick pans use a finish of silica (silicon dioxide) to prevent sticking.
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
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 ...

Teflon flu, aka polymer fume fever, is a term used to describe people who have gotten sick after being exposed to fumes from Teflon pans, according to the National Capital Poison Center.
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
The FDA’s recent ban on Red Dye No. 3, set to take effect by 2027 for foods and 2028 for drugs, marks a significant step in addressing safety concerns over artificial food dyes in the U.S. food ...
