HDSF is widely used in the electronics industry as a dielectric material in semiconductor manufacturing. Its high thermal stability and low electrical conductivity make it suitable for insulating layers in advanced microchips. It is also employed in the production of protective coatings for optical fibers, enhancing durability and moisture resistance. Due to its inert nature, HDSF serves as a key component in specialty sealants and gaskets used in corrosive environments. Additionally, it finds application in aerospace materials where resistance to extreme temperatures and chemical exposure is critical.
