Product Introduction

Product introduction:Optical Fiber PP filling gel (LT-390) is made up by imported high viscosity synthesis oil, ester oil, and high molecular synthetic material which are combined by advanced production technique. This series has excellent thixotropic, steadily temperature performance, colloid stability and good compatibility with PP tube. Optical Fiber PP filling Gel can apply to prevent problem arises under any circumstances, and guarantee the optical cable transmission performance.

Technical parameters:

Cold Application Type LT-390 PP Optical Fiber Filling Gel

1、General Technical Requirements

Filling gel is needed to be homogeneous, hydrogen absorption, and does not include any dust, metal particles, and other impurities. It should be no sight visible air bubbles, and the mold should be no nutrition. Filling gel should be non-toxic, no stimulation to the skin.
