Perfluorinated compounds
I want to introduct something about solar mould junction box. 1.PV-GZX0602 junction box provide to user with safty,swifty and reliable way to connect. The product has got Germany TUV Certificate 2.Appearance Dimension94mm×94mm×28mm ;* Rated Current16A; * Rated VoltageDC 1000V ;* Ambient Temperature-40~+85; * Class Degreecalss ; * Waterproof DegreeIP65; * Rated Connecting Capacity: 4mm2; * MaterialAmerican GE PPO; solar mould junction box Mo Note: PFC refers to more than one chemical. Please see PFC.Perfluorinated compounds (also PFC's) refer to compounds manufactured with fluorine, and noted particularly due to dangers in humans. They are a family of fluorine-containing chemicals with unique properties to make materials stain and stick resistant, and are widely used in diverse applications. Like their halogenated counterparts, PBDE's and PCB's, PFCs are incredibly resistant to breakdown (see persistent organic pollutant) and are turning up in unexpected places around the world. Although these chemicals have been used since the 1950s in countless familiar products, theye been subjected to little government testing. Perfluorocarbons are a subset of perflourinated compounds.There are many forms of PFCs, but the two getting attention recently are:PFOA or perfluorooctanoic acid, used to make Teflon products. PFOS or perfluorooctanesulfonic acid, a breakdown product of chemicals formerly used to make Scotchgard products. Types of products with PFC'sFood Packaging Grease-resistant food packaging and paper products, such as microwave popcorn bags and pizza boxes, contain PFCs. Stain, Oil or Water resistant items Carpet w/kidPFOS was used until 2002 in the manufacture of 3M's Scotchgard treatment, used on carpet, furniture, and clothing. PFOA is used to make DuPont's Teflon product, famous for its use in non-stick cookware. If Teflon-coated pans are overheated, PFOA is released. teflon frying pan PFCs are in cleaning and personal-care products like shampoo, dental floss, and denture cleaners. Much waterproof clothing contains PFCs. Medical Applications, for more complete list see perfluorocarbons Eye surgery Liquid breathing Imaging Artificial blood Electronics Dielectric fluid Ion-mass spectroscopy Refrigerants Adverse Health AffectsPFOA is a likely human carcinogen; it causes liver, pancreatic, testicular, and mammary gland tumors in laboratory animals. PFOS causes liver and thryoid cancer in rats. PFCs cause a range of other problems in laboratory animals, including liver and kidney damage, as well as reproductive problems. PFOA half-life in our bodies, or the time it would take to expel half of a dose, is estimated at more than 4 years. PFOS half-life is estimated at more than 8 years.
