It is a type of hot melting electric filling gel, which refining low-temperature high-purity mineral oil, hydrogenated white oil and thickener as main material to combine by advanced technique. It designed for excellent high and low temperature property, excellent electric property and dielectric property
hot application type LTD-90 electric cable filling gel technical specification
Filling gel is needed to be homogeneous, water repellency, 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.
