PBT Standard for Optical Cables
When selecting PBT (Polybutylene Terephthalate) material suitable for optical cable loose tubes, it is necessary to comprehensively consider the material's mechanical properties, thermal stability, processing performance, environmental adaptability, and compatibility with optical. It has excellent processability, stable size, good surface finish, excellent heat resistance, aging resistance and chemical corrosion resistance, so it is extremely versatile. Fiber optic cables are designed to provide high-speed, no-signal-loss, and EMI-free communication in telecommunication, powergrid, datacenter, broadband, and industrial applications. These materials are strategically employed to fortify and shield the delicate optical fibers within the cable. The PBT material is characterized by comprising the following materials in percentage by weight: 90 to 95 percent of PBT, 3 to 8 percent of polycarbonate, 1 to 5 percent of. PBT resin is a widely used loose buffer-tube material because it works well across a wider range of conditions.
