| Teflon™ AF is a family of amorphous fluoroplastics similar to other amorphous polymers in optical clarity and mechanical properties, including strength. They also resemble fluoroplastics in their performance over a wide range of temperatures, outstanding electrical properties, and chemical resistance. They are distinct from other fluoroplastics in that they are soluble in selected solvents and have high gas permeability, high compressibility, high creep resistance, and low thermal conductivity. They have the lowest dielectric constant and refractive index of any known fluoroplastic. Products labeled AF 2400 and AF 2400 X are equivalent. Applications: optoelectronic devices, low-refractive index coating or covering for optical devices.Information provided by Chemours. |
