Teflon coated cookware - what is it?
My employer asked me to pick up either a pot or a pan made of stainless steel, with a teflon finish, and no other kind of finish. I went to a store called The Bay (www.hbc.com/bay) which is probably the largest high end department stores in Canada, and possibly one of the best in North America. They had about 30 different brands of pots and pans and many were stainless steel, but not one of them had a "Teflon" coating. There was T-Fal and Stoneware and a couple starting with an E, but no Teflon.
Can someone tell me if teflon is a brand name or a product that goes into other non-stick coatings. I would really like to find out.
Please either give me the answer or tell me where to look on the web.
Teflon is a trademark of Dupont for PTFE--polytetrafluoroethylene. It is a very slippery, very chemical resistant, very high temperature plastic, which I always believed to have been invented by Dupont.
The company which makes T-Fal also claims to be the inventor of PTFE. I would not want to slander either by saying there is no difference, but for your boss' purpose, I think the answer is "T-Fal = Teflon = non-stick".
Nonetheless, most non-stick cookware is aluminum rather than stainless steel. You may need to shop a bit to find stainless cookware with a non-stick coating =>

As said Ted, Teflon* is a trademark of DuPont, and under this name they sell different polymers and copolymers like PTFE, FEP, PFA, ETFE, etc. There are in the market other trade names for PTFE coatings like Silverstone, Teflon S, Teflon 2, from Dupont; Xylan, Excalibur, Dykor, Xylar from Whitford Plastics, etc. There are some companies who sell PTFE dispersions to be applied on frying pans with different names.
