Product Introduction

Production introduction:Type LT-410-B optical fiber filling gel adopts low viscosity synthetic oil and high molecular synthetic material 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-410-B also has steadily temperature performance between -50°C to 100°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.

Technical parameters:
