  • Product model:Type ZLT-60
  • Product Features:Low density (density of ordinary cable gel is around 0.95g/cm3 , the density of ZLT-60 is around 0.55g/cm3 ), density adjustable, reduces cable weight after filling gel; high thixotropic index, stable mechanical property, heat stability, easy to filling;
  • Applications:Apply to the gaps of filling between the optical cable loose tubes, or air gaps of multi conductor wire and cable core, or any gaps between constructions of cable components, in order to avoid that liquid moves into optical cable, to provide excellent fun
  • Technical Requirements:

Product Introduction

 The type ZLT-60 is a new developed low density optical cable filling gel. Because of quite low density, it can directly reduce the cost of product of optical cable, decrease cable weight; to make sure that cable is safety applied under any circumstances such as river, sea, lake, mountain, land and etc.


Cold application type ZLT-60 low density 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.
