Hyflon® AD 40H is an amorphous perfluoro-polymer available in powder form. Hyflon® AD polymers resemble semicrystalline perfluoropolymers in their performance properties as they exhibit high temperature stability, excellent hydrophobicity and chemical resistance as well as very low surface energy. Key distinctive feature of Hyflon AD polymers is that they are soluble in selected solvents. In particular, their high solubility in perfluorinated solvents and their low solution viscosities make them suitable for solution process technologies. Hyflon® AD can provide uniform and thin films or coatings (down to submicron thicknesses if required) by casting or coating techniques and thermal treatments, well below the typical baking temperatures of semicrystalline perfluoro-polymers. Examples of typical applications include protective coatings, interlayer dielectric films and pellicles for electronics. Main features of Hyflon® AD 40H include: - Amorphous glassy polymer structure - Solubility in perfluorinated solvent - Low dielectric constant of 2.0 at 1 kHz - Excellent optical properties -- high UV transmittance -- low refractive index
