Core Features
1. Firm printing: special scratch-resistant ink. Resistant to ointment, no fading or bleeding. Text will not blur or peel off after contact with the filling gel inside the cable. Markings remain legible for long-term underground and pipeline applications.
2. Excellent mechanical toughness and high tear resistance: PET substrate features high tensile strength, thinness and flexibility. It is not prone to breakage during cable wrapping, and will not crack when bent or twisted, compatible with high-speed cabling equipment.
3. Good thermal stability: capable of withstanding short-term high temperature during sheath extrusion. No deformation under heat, no ink melting, and no contamination of other materials of the cable core.
4. Outstanding chemical stability: resistant to acid, alkali, salt spray and mould. It has good compatibility with PBT, PP tape, water-blocking materials and cable gel, and will not corrode optical fibres and auxiliary cable materials.
5. Insulating property and ultra-low water absorption: non-metallic insulating material, non-conductive. Barely absorbs water, maintains stable dimensions without swelling in humid underground environments.
