Perfluorooctanoic acid (PFOA), also known as C8 and perfluorooctanoate, is a synthetic perfluorinated carboxylic acid and fluorosurfactant.

PFOA can affect environment, and its usage is being monitored by US Environmental Protection Agency (EPA)


EFiRON® SPC has been successfully developed by Fospia, with our patented Fluorine polymer technology.


EFiRON® SPC excludes not only PFOA but also PFOA generating precursors, maintaining excellent optical, mechanical, and thermal properties similar to EFiRON® PC. All the properties can be tailored upon customers' demands.


EFiRON® SPC can ensure environmentally healthy conditions for both manufacturer and final customers in specialty optical fibers, along with various biomedical applications.
