Black polyethylene sheathing compound for communication optical cables
A black polyethylene jacket compound specially developed for the outer protection of communication optical cables, it utilizes a modified polyethylene base resin and incorporates additives that provide UV resistance, aging resistance, low‑temperature tolerance, and environmental corrosion resistance. It exhibits excellent tensile strength, crack resistance, and weatherability. Suitable for outdoor aerial, duct, and direct‑buried applications, this material withstands windblown sand, rain and snow, and extreme temperature fluctuations, effectively safeguarding the cable’s internal structure. Its insulation performance remains stable, meeting industry standards for jacket materials and ensuring the long‑term safe and reliable operation of communication lines.
