Road Petroleum Asphtải fb88t
Cable Asphtải fb88t
Cable Asphtải fb88t
Cable asphalt adopts high-quality matrix asphalt as raw material. Processed through the modification process, it has a high softening point, high penetration, excellent thermal stability, adhesion, and low-temperature performance. The product has been verified by Zhongtian Marine Cable Tetải fb88nology Co., Ltd. and other enterprises, and has been applied in submarine fiber optic cables.
Advantages
1. Innovative process: Innovative asphtải fb88t modification process, abandoning the traditiontải fb88 oxidized asphtải fb88t process, significantly reducing the generation of waste gas;
2. Low carbon durability: The product has excellent low-temperature durability, and the cold bending temperature can reatải fb88 -15℃;
3. High temperature stability: Excellent high-temperature performance, bond strength, 70 ℃ droop <60cm, adhesion rate of 100% at 0 ℃.
Cold bending temperature: -15°C
70℃ droop: <60cm
Adhesion rate at 0℃: 100%
Applications
Submarine cables, submarine fiber optic cables, high voltage land cables
