Product Introduction
Production introduction：Type LT-400 optical cable adopts high viscosity GTL process oil and high molecular synthetic material as main base materials. They are combined to be silicic optical fiber filling gel by advanced production technique whose features are high temperature resistance, excellent high-and-low temperature performance; excellent thixotropic property and excellent pump lose property. According to various requirements of clients, the technical index of viscosity, penetration, thixotropic and etc. could be adjust in order to satisfy requirements of filling technique.
Technical parameters：
Cold application type LT-410 optical fiber filling gel Technical Specification
1、general technical requirements
Filling gel is needed to be homogeneous, hydrogen absorption, and does not include any dust, metal particles, and other impurities. It should be no sight visible air bubbles, and the mold should be no nutrition. Filling gel should be non-toxic, no stimulation to the skin.
