DuPont's PFOA progress

I have not realized how vital the use of perfluorooctanoic acid (PFOA) is in many products.

The company's goal is to no longer produce, buy or use PFOA by 2015 or earlier if possible.

Unfortunately, trace levels of PFOA emissions have been found as an unintended byproducts in fluorotelomer products, such as those used in repellants and firefighting foams. For many years PFOA has been used as a processing aid in the manufacture of fluoropolymers that went to a lot of products because of its versatile and durable and possess unique properties such as non-stick characteristics and heat and chemical-resistance.
