Polyethylene (PE) optical cable sheath material is a high-performance protective layer material designed specifically for optical fiber cables. It has excellent mechanical strength, weather resistance and environmental adaptability, and is widely used as an outer sheath of optical cables in the fields of communications, electricity, transportation, etc. Its low friction coefficient, UV resistance and chemical corrosion resistance can ensure long-term stable operation of cables in complex environments.
Product Features:
1. Excellent mechanical properties
– High tensile strength and toughness, effectively resisting stretching, extrusion and wear during construction.
– Good flexibility, easy bending operation during cable laying.
2. Weather resistance and durability
– Anti-ultraviolet (UV) additive formula to prevent aging and cracking caused by long-term outdoor exposure.
– Adapt to extreme temperatures (-40°C to +70°C), suitable for a variety of climate conditions such as cold and tropical zones.
3. Safety
– Optional flame retardant grade (such as UL94 V-0) to meet stringent fire protection requirements.
4. Chemical stability
– Resistant to acid, alkali, salt spray and grease corrosion, suitable for harsh environments such as industrial areas and coastal areas.
5. Low friction coefficient
– Reduce the friction resistance when laying cables in pipelines and reduce the difficulty of construction.
