Product Introduction

 Optical cable water-blocking filling gel adopts refining low-temperature high-purity mineral oil, hydrogenated white oil and thickener as main material to combine by advanced technique. The features of ZLT-290 are excellent high and low temperature property, efficiency thixotropy, pump transports property , alt tolerance, temperature resistance, excellent water-blocking property, and able to solve the problem of water seepage under any circumstances and weathers.


cold application type ZLT-290 optical cable water-blocking 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.
