Q. Can I use a Hot Glue Gun to hold the Fiber in place?
A. Yes, it should be fine to hot glue the fiber. The melt temperature for a low melt gun is 150 to 280C. The melt temperature for the fiber (which is a PMMA material) is 320C. Hence, it is reasonably mild on the fiber. However, do not use a high temperature glue gun which runs at 400C as this will surely melt the fiber.
