Q: I’m looking for a polymer fastener that can withstand ultraviolet radiation, but is also FDA approved as this is for a pharmaceutical application. Temperatures are around 100C.
A: For this application, a good choice would be PVDF fasteners. PVDF screws are both FDA approved and are ideal for handling ultraviolet radiation. They are often used in pharmaceutical applications. Their max temperature rating is about 150C so they should be a good solution.
