Core Features

1. Excellent low-temperature resistance and low-temperature toughness. HDPE can maintain its toughness at -40℃ and is not prone to brittle cracking, making it suitable for outdoor optical cables in frigid northern regions.

2. Extremely low water absorption, moisture-proof and waterproof. As a non-polar material, it barely absorbs water and resists water vapor penetration. It has good compatibility with optical cable filling grease without swelling or chemical reactions, ideal for buried and pipeline humid environments.

3. Outstanding chemical stability. It resists weak acids, weak alkalis and salt spray, and is anti-microbial mildew. It is insoluble in common solvents at room temperature and remains stable for a long time in underground soil environments.

4. Superior electrical insulation performance. It features high insulation resistance and low dielectric loss, and is non-conductive, so it will not interfere with optical signal transmission.

5. Good processability. Being thermoplastic, it enables smooth melt extrusion and fast forming, suitable for high-speed extrusion production of optical cable sheaths. Carbon black can be added to improve its UV resistance and weatherability.
