Optical Fiber UV Coated, Acts as a Thermal Insulator

Published: May 10, 2018
, Last updated: September 17, 2025

Because most optical fiber is typically UV coated, which acts as a thermal insulator, there is almost no absorption of heat by the fiber. This physically causes many problems with polymer extrusion as differential cooling causes many issues in post-extrusion stress.

With these physical differences in mind, we need to recognize that many of the components look the same. You have an extruder which is a plastic melting pump, a water trough, which cools the plastic and a capstan that pulls the material through at a fixed rate. And there is typically a form of diameter control with some form of controlled payoff and take-up devices.
