Hyflon® AD is a family of amorphous perfluoropolymers which resemble semi-crystalline ones in their performance properties.
Key characteristics of this family are:
High temperature stability
Good chemical resistance
Excellent hydrophobicity
Very low surface energy
Low dielectric constant
Very high gas permeability and selectivity
Outstanding optical properties (i.e., high UV transmittance, low refractive index)
A key distinctive feature of Hyflon® AD polymers is their solubility in selected solvents. In particular, their high solubility in perfluorinated solvents and their low solution viscosities make Hyflon® AD suitable for solution process technologies.
Hyflon® AD can provide uniform and thin films or coatings (down to submicron thicknesses) by casting or coating techniques and thermal treatments, well below the typical baking temperatures of semi-crystalline perfluoropolymers.
Markets and Applications
Typical industries and application served by Hyflon® AD are:
Filtration: Films and membranes for gas separation
