Product Introduction

 It is a type of silica gel, which refining high-purity mineral oil, naphthenic oil, water-blocking insulating polymer as main material to combine by advanced technique. It is designed for applying to fill into electric cable communication modules. The features are High and low temperature property, damp-proof, smoke protection, mold-proof, high insulation transmission property. The RTD-130 is able to protect that modules, related materials and facilities to be eroded in order to extend service life and ensure safe reliability.


hot application type RTD-130 silica 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.
