FIELD: manufacturing technology.
SUBSTANCE: invention relates to fiber-optic cable components. Extruded protective component of a fiber-optic cable contains a polymer composition containing polybutylene terephthalate, an ethylene-based polymer and a maleinised ethylene-based polymer. Optionally, the polymer composition can additionally contain one or more additives, such as filler. Components of the fiber-optic cable can be selected, for example, from buffer tubes, inner tubes and profiled cores.
EFFECT: invention reduces shrinkage, improves retention of properties after aging in a lubricant and maintains Izod impact strength with notch of components of the fiber-optic cables.
