General description

Perfluorooctanoic acid (PFOA) is a perfluorinated carboxylic acid, that serves as a building block to synthesize perfluoroalkyl-substituted compounds, polymers, and polymeric materials.

Application

PFOA can be used:
  • As a water and oil-repellent coatings on textiles and paper products
  • In the synthesis of fluorotelomer alcohols, which serve as feedstocks to produce polymers, surfactants, textile treatments, and packaging materials
  • As an emulsifier in the production of polytetrafluoroethylene (PTFE) and fluoroelastomers
  • As a reactive intermediate in the synthesis of fluoroacrylic esters
