Applications：0.6/0.9mm Tight Buffer Fiber is produced as that fiber is sheathed by buffer material. Extrusion Material PVC、LSZH 、Hytrel、Nylon etc.

 Features:

Self-centering extruder head designs

Tensions of optical fiber Payoff  and takeup are accurate and constant

Fast and easy set-up of the line allows easy operation.

The modular line component concept allows the  production of the buffers for a variety of different kind of fiber optical indoor cables.
