Protect the Core
Polymer jacket extrusion is the process of forming a polymer jacket of various thicknesses around a core of high-performance fibers, adding protection from mechanical, environmental or chemical damage.
With a wide variety of polymers available, each polymer jacket material is selected to optimize flex, chemical, temperature, & UV resistance according to your application’s unique requirements.
