Perflourinated Chemicals (PFCs) are the key ingredient in many stain, water and grease repellent coatings that make outdoor jackets water tight and frying pans non sticky. These chemicals consist of long molecules that contain carbon chains surrounded by fluorine. That bond between carbon and fluorine is incredibly tight. They interact so strongly with each other that the normal, inter-molecular forces, that cause substances to stick to each other, don’t stand a chance.While some types of PFCs are either safe or
