Perfluorooctanoic acid(PFOA)
Product description
Perfluorooctanoic acid(PFOA) is a per-fluorocarbon monocarboxylic acid that is an organic strong acid with low surface tension and high surface activity, and is used as efficient surfactant,dispersing agent and additive.The perfluorooctanoic acid and it's derogates as important organic intermediates can be used for synthesizing fluoridated hydrophobic and oleo phobic agent, and leather finishing agent. The temperature should be controlled at 140•c or below when the product is heated to melt, protecting it from decomposing.

Application
Perfuorooctanoic acid ammonium salt or sodium salt are anion surfactant with excellent performance, and indispensable raw materials for synthesizing fluororesin(such as PTFE,PVDF,FEP，and ETFE)and FLM. The perfluorooctanoic acid is an efficient metal detergent,as well as intermediate for synthesizing hydrophobic and oleo phobic leather, paper and fiber finishing agent . It's detonates can be used as chromatographic fixer with high efficiency and high resolution.
