PP filling rope, also known as PP filler rope, is a type of cable filling material that is made of polypropylene. It is used to fill the gaps and spaces in the cable to provide additional support and protection to the cable structure. PP filling rope is known for its excellent tensile strength, resistance to moisture and chemicals, and durability, which makes it a preferred choice in various industries such as telecommunications, power, and transportation. The use of PP filling rope also helps to improve the cable’s mechanical and electrical properties, such as insulation, voltage resistance, and flame retardancy.
