Product Introduction

The type LTD-150 is not made up by traditional technical formula, but it uses high viscosity GTL oil, hydrophobicity thickener, high purity polyisobutene and insulating polymeric materials. The features of LTD-150 are high melting temperature, damp-proof function, water resistance function, insulation resistance function, low cable depletion, and compatibility with cable inside and outside tube. The type LTD-150 is designed for simple processing technology, clean production environment, non-pollution, excellent water resistance, which is widely used in optical cable communication industrie.


Cold application type LTD-150 optical cable filling gel technical specification


Filling gel is needed to be homogeneous, water repellency, insulating, and does not include any dust, metal particles, and other impurities. It should be no nutrition. Filling gel should be non-toxic, no stimulation to the skin.
