Product Introduction
Product introduction：Type LT-420 optical fiber filling gel adopts high viscosity GTL process oil, high molecular synthetic material and organic thickener as main base materials. They are combined to be non-silicon optical fiber filling gel by advanced production technique whose features are low density, excellent temperature performance, high thixotropic index, wide application, tiny acid value and hydrogen evolution value. Type LT-420 also has steadily temperature performance between -45°C to 80°C. 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.
