FEP is inert to UVC and does not become brittle or discoloured over time. The added-bonus is that very little UVC is absorbed by FEP and so the output of the lamp is not greatly affected.
Fluoroplastics can also be sterilised using ETO, autoclaving and gamma methods.
We worked with a UVC sterilisation customer to create a custom UVC lamp cover. The coating needed to follow strict criteria to fit the UVC sterilisation application precisely.
