Core Features

1. High tensile strength, controllable elongation and high breaking strength with moderate elongation at break. It is not prone to breakage during high-speed cabling and winding. When binding loose tubes of cable cores, it can maintain constant binding force and prevent the cable core from loosening and shifting.

2. Low thermal shrinkage rate and excellent thermal stability. It can withstand short-term high temperature in the sheath extrusion process, and will not shrink significantly to damage loose tubes and optical fibers when heated, ensuring stable internal structure of optical cables.

3. Extremely low water absorption and good compatibility with grease. It barely absorbs water, does not swell when in contact with optical cable filling gel (cable grease), and does not precipitate harmful substances. Suitable for optical cables used in pipelines and direct burial under humid conditions.

4. Chemical resistance, mildew resistance and microbial resistance. It resists weak acids, weak alkalis and salt spray, and is not susceptible to mildew or insect damage. Its performance degrades slowly during long-term underground service.

5. Insulating and lightweight non-metallic insulating material. It produces no electromagnetic induction and will not interfere with optical signal transmission. With low density, it does not add extra weight to optical cables.

6. Excellent processability with few fuzzes and low powder shedding, compatible with high-speed cabling yarn winding equipment. It can be dyed to produce colored binding yarns for convenient fiber sequence identification during production.
