TEXMO PLB HDPE Duct & Micro Duct are manufacured as per norms of G.R.No. TEC/GR/TX/CDS – 008/03 MAR-11 & GR/MDS-01/01 Feb 2010 . It provides housing for fibre optic cable and metal cable, used as basic backbone in communication. TEXMO as a large processor of plastic material in India has introduced PVC, HDPE, Plain, Permanently Lubricated, Ribbed, Tracer & Large diameter ducts for safe placement of cables and future up gradation and replacement of damaged cables. TEXMO provides easy cable insertion and avoid damaging of cables due to its inner surface is very smooth. TEXMO believes in enhancing customer satisfaction and “TEXMO” brand ficilitate for safe placement of cables and future upgradation and easy replacement of damaged cables with a permanent conduit with permanent Lubrication.

  • Low Internal co-efficient of friction facilitate smooth cable insertion and avoid damage.
  • Ductile and tough.
  • Various temperature service range.
  • Resistant to UV and chemicals.
  • Sufficient protection of cable in un-usually stony ground during tectonic movement.
  • Protection against damage during excavation work if required on a later stage.
  • Industrial
    • TEXMO co-extruded permanently lubricated HDPE ducts are used for laying Optical Fibre cable (OFC) as underground conduits.

The main raw material being used for the manufacture of permanently Lubricated Ducts is High Density Polyethylene (HDPE). This raw material is confroming to IS : 7328-1992 or to any other equivalent standard. Testing of this material as per IS 2530 or ISO 1183 & ISO 1133 the following requirements are met strictly.

  • Density : 0.940 to 0.958 gm/cc at 27° C
  • Melt flow Index : 0.20 to 1.1. gm/10 min at 190° C and 5Kg Load.
