PBT optical cable recycled materials
Through advanced depolymerization and transesterification processes, recycled PET is converted into high-purity bis (2-hydroxyethyl) terephthalate (BHET) monomers (≥95% purity), which are subsequently polymerized with 1,4-butanediol (BDO) to yield PBT with mechanical properties. Some optic cable manufacturers list PBT materials as the procurement scope of Class A materials. Since the optical fiber is light, thin and brittle, a loose tube is required to combine the optical fiber in the optical cable structure. Producing the fiber optic cables that connect us around the globe is a complex and massive process. Polybutylene terephthalate recycled content grade represents a transformative approach to sustainable engineering thermoplastics, leveraging chemical recycling of post-consumer and post-industrial polyethylene terephthalate (PET) to produce high-performance PBT resins. It has excellent processability, stable size, good surface finish, excellent heat resistance, aging resistance and chemical corrosion. These materials are strategically employed to fortify and shield the delicate optical fibers within the cable. These cables, originally installed to support communication networks, become obsolete due to technological advancements.
