| description | A flame retardant air-blown microcable, comprising a central reinforcement member (1), wherein a loose tube (2) is stranded on an outer surface of the central reinforcement member (1), an optical fiber unit (4) and a first water blocking substance are provided in the loose tube (2), wherein the optical fiber unit (4) is an optical fiber bundle, the first water blocking substance is a water-blocking fiber paste, an outer sheath (6) is clad on an outer surface of the stranded loose tube (2), and the outer sheath (6) is further filled therein with a cable paste (7). The outer sheath (6) comprises following components: 50-60 parts of ethylene-vinyl acetate copolymer EVA, linear low-density polyethylene LLDPE, flame retardant, synergistic flame retardant, plasticizer, lubricant, coupling agent, compatilizer, antioxidant, carbon black, and amide slipping agent. It has a small preparation thickness, effectively ensuring the mechanical performances, and has good flame-retardant performance, ensuring excellent performances of the optical cable such as meeting requirement of category C bunched combustion, high light transmittance, and a low acid value. |
