Fluorinated Compounds In Carpets

Epa recently posted a draft method to measure a group of 24 pfas compounds in groundwater surface water and wastewater samples.

Fluorinated compounds in carpets.

Because perfluorinated compounds pfcs repel both water and oil they are used as durable repellent treatments for textiles such as outdoor clothes and for home products such as carpets in addition pfcs are widely used in the production of fluoropolymers such as polytetrafluoroethylene trade name teflon which is widely used in coatings for electronic automotive and outdoor products. The compositions may also contain a source of peroxygen bleach and or a fluorinated compound. Some of the stain resistant coatings that carpeting is treated with contain perfluorinated compounds pfcs such as perfluorooctanoic acid pfoa and their corresponding homologues c6 c14 acids as well as fluorotelomer alcohols and. Phased out due to the increasing evidence that bioaccumulation of the chemicals is significant and that in humans the compounds persist with a.

Once final it will be included in the sw846 compendium. Perfluorinated compounds pfcs are a class of anthropogenic chemicals incorporated over six decades into a wide range of industrial and consumer use products including surface treatments for carpets and textiles paper and packaging non stick cookware firefighting foams and insecticides. The cleaning compositions contain nanolatexes and the methods for cleaning carpets and other materials use such compositions. Non fluorinated omniphobic coatings for stain resistant textiles epa contract number.

Symposium paper one of the emerging waste streams that will likely be disposed of in combustors is carpet due to its high heating value and combustibility. Cleaning compositions and methods for cleaning carpets and other materials are disclosed. In particular has come to be expected in a wide variety of products such as carpets shirts ties and sofas. The extremely strong carbon fluorine bond the strongest in organic chemistry makes them thermally.

Myths versus facts long chain highly fluorinated chemicals including pfoa pfos and other c8 compounds were used for decades to give water repellent stain resistant and non stick properties to furnishings carpets food packaging outdoor gear and other products.
