Requirements for PBT for Optical Cables

PBT for optical cables must combine high mechanical strength, thermal stability, hydrolysis resistance, chemical resistance, and processability to protect delicate optical fibers and ensure long-term reliability.Mechanical Properties

PBT used in optical cable loose tubes must have high flexural modulus and tensile strength to withstand bending, stretching, and flattening during installation and operation, preventing fiber breakage or microbending . High elongation at break (typically >50%) and retention after aging ensures flexibility and resistance to brittleness, while creep resistance maintains the stable excess length of optical fibers over time .

Thermal and Environmental Stability

The material must exhibit a low thermal expansion coefficient to maintain dimensional stability under temperature fluctuations and high thermal stability to resist degradation during high-speed extrusion and service . PBT should also have low water absorption and high hydrolysis resistance (hydrolysis rate
