China Suppliers Factory Cold Application Type Optical Cable Filling Gel - Water Repellent, High Resistance, 180kg
Product Introduction
Product introduction: Optical cable filling gel adopts GTL process oil and high molecular synthetic material as main base materials. They are combined to be soft, low-viscosity, high thixotropic index, colorless transparent filling gel by advanced production technique whose features has water repellency, excellent processing technic and high- and-low temperature properties. It can keep soft under -40℃ and no-drip on the high temperature of 80℃. Filling process is simple which can be filled at general temperature, especially suitable for particular cable sheath and cable core. According to various requirements of clients, the technical index of viscosity, penetration, thixotropic and etc. that could be adjust in order to satisfy requirements of filling technique.
