Introduction Polytetrafluoroethylene (PTFE)‚ more commonly known as Teflon‚ is a polymer. Polymer is a substance which contains many structural units that are joined the same type of linkage.(1) Hence‚ the molecular structure of polytetrafluoroethylene is based on a chain of carbon atoms. However‚ unlike some other fluoropolymers‚ in Teflon the chain is completely surrounded by fluorine atoms.(2) There is a very strong bond between fluorine atoms and the carbon as the fluorine atoms act as a protective

GORE-TEX 1. INTRODUCTION There are plenty of clothing options out in the market to keep you warm‚ but how about to keep you dry in wet conditions? Being dry is one of the key components to keeping warm so this is essential. That is were GORE-TEX comes in. GORE-TEX is an inner membrane layer in outdoor clothing containing over nine billion microscopic pores per square inch (Figure 2). These pores are each twenty thousand times smaller then a water droplet but seven hundred times larger then a water

There are many uses of Teflon but the most widely used application is in cookware. PFOA is the main ingredient used in the production of Teflon‚ and there is a claim that there is a trace amount of PFOA left in the cookware after the manufacturing process is completed. And it is also claimed that this PFOA could be harmful to people using the cookware. Research conducted by the US food and drug administration revealed that there is a very small amount of PFOA found in cookware made by DuPont. DuPont’s

We only apply coating and do not undertake lining. Let us describe below the difference between coating and lining‚ as we understand: A coating is applied to a thickness of 10 microns to 1500 microns (0.01mm to 1.5mm). On the other hand lining can be between 3mm to 5mm or 3000 microns to 5000 microns. Lining is normally preferred where one needs to store various corrosive chemicals. Fluoropolymer lining is normally a sheet of Teflon/PFA/Tefzel/PVDF material either stuck to the shape of the vessel/item

and spoons are both kitchen and eating utensils. Non-stick pans are cooking pans made from or coated with materials designed to prevent food from sticking to their surface during the cooking process. Most non-stick pans are made using polytetrafluoroethylene (e.g. DuPont’s Teflon) coating although newer materials are also used. Health concerns have been raised regarding use of PTFE as a cooking pan coating. Pressure cooking is the process of cooking food‚ using water or other cooking liquid‚
