Cold application type LT-460 low density optical fiber filling gel

  • Product model:Type LT-460
  • Product Features:low density, typical value:0.55g/ cm3 , excellent high and low temperature property, volume do not expand on 100℃ high temperature, volume do not shrink on -50 ℃ low temperature; stable structure, excellent shear property, keeps structure of paste stable
  • Applications:Apply to filling in the optical fiber (bundle) or optical fiber loose casing or skeleton groove, to prevent water into cable vertically infiltrating, to provide good functions of waterproof, moisture proof, buffering to optical fiber.
  • Technical Requirements:

Product Introduction

Product introduction:the product is a type of low density optical fiber filling gel. Because of low density, it can directly reduce the cost of product of optical fiber, decrease the self- weight of optical fiber and make sure non-drip at high temperature. The oiliness of pasty fluid is not enough, so it is easy to construction and going on with work of optical fiber.

Technical parameters:

Cold application type LT-460 low density optical fiber filling gel technical specification


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.
