AI Technical Summary
Existing communication cable sheath materials do not meet the requirements for communication cable use in terms of oil resistance and tear resistance, and there is also the problem of halogen release.
Sheath materials are prepared by using specific types and amounts of raw material components, including ethylene-vinyl acetate copolymer, ethylene-butyl acrylate copolymer, compatibilizer, composite flame retardant, lubricant, anti-aging and antioxidant agent, and crosslinking agent, through an irradiation crosslinking process.
After irradiation crosslinking, the material exhibits high tear resistance, low smoke and halogen-free properties, high flame retardancy, oil resistance that meets the MIL-DTL-24643C standard, and maintains good mechanical properties after short-term aging.
