PBT, with its high viscosity, low carboxyl end-group content, and exceptional resistance to hydrolysis, emerges as an ideal choice for fiber optic loose tubes and other related applications. Polybutylene terephthalate (PBT) is a highly crystalline engineering plastic. It has excellent processability, stable size, good surface finish, excellent heat resistance, aging resistance and chemical corrosion resistance, so it is extremely versatile. In the communication optical cable industry. Fiber optic cables are designed to provide high-speed, no-signal-loss, and EMI-free communication in telecommunication, powergrid, datacenter, broadband, and industrial applications. Each optical cable is constructed using a precise combination of optical fibers, strength members, buffer tubes. 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 fiber gel. Loose buffer tube diameter varies with the number of fibers enclosed, but is typically 2 to 2. It usually has a wall thickness of 0. As a leading manufacturer of modified plastic pellets, TOPONEW takes immense pride in introducing PBT as a high-viscosity, extrusion-grade resin with low carboxyl.
