Perfluorooctanoic Acid(PFOA)

Perfluorooctanoic Acid(PFOA)
Product Detailed
PFOA is a kind of strong organic acid, which has low surface tension and high surface activity, being used as surfactant... PFOA (Perfluorooctanoic Acid) Conformable with: Q/DYS 006-2007 PFOA is a kind of strong organic acid, which has low surface tension and high surface activity, being used as surfactant, dispersant and additive. PFOA and its derivatives are important intermediates for fluoride hydrophobic and hydrophilic agent, and leather finishing agent.  PFOA (Perfluorooctanoic Acid)Quality Specification

Main Applications

The ammonium or sodium salt of PFOA is excellent anion surfactant and indispensable for preparation of fluoride resin (PTFE, PVDF, FEP, ETFE) and FKM. PEOA is also effective metal deterget and intermediates of finishing agent for lydrophobic and hydrophilic leather, paper, and fiber. Its ester derivatives can be used as effective and high resolution stationary liquid for chromatogram analysis. Package, Transportation and Storage1,The product is stored in wide-mouth glass bottle, 1.5kg. Each attached attached quality detection report form, and quality certificate which imdicate product name, net weight, grade, production date and manufacturer.2,The product is transported according to dangerous product, and strong shock should be avoided.3,Stored in dry and clean places, and room temperature not above 40°C. Light and heat should be avoided.4,When heating to melt the product, temperature should not exceed 140°C to prevent decompose.
