Product Overview

PP Cable Filler Yarn / PP Filler Rope is an essential auxiliary cable material, manufactured from 100% virgin polypropylene or PP compound with CaCO₃ filler. Available in both twisted and untwisted (fibrillated split‑film) versions, it fills inner gaps inside cable cores to keep cables round‑shaped, stable in structure and consistent in appearance.

Boasting outstanding chemical stability, high mechanical tenacity, soft elasticity and non‑hygroscopic property, our PP filler rope will not rot, mildew or absorb moisture during long‑term service inside cables. It stays anti‑slip during cable production and delivers uniform round filling performance for diverse wire‑cable projects.

Jiangxi Longtai is a trusted Chinese leading manufacturer & supplier of PP cable filler yarn, serving wire and cable manufacturers across the globe. Every production step — raw material procurement, extrusion, fibrillation, twisting to finished spool winding — is under strict quality control, fully meeting strict technical requirements from cable producers worldwide.

In cable manufacturing, cable filler is used to make the cable round, maintain its shape, and fill the gaps between insulated cores. This is especially important for multicore cables.

How cable filler makes a cable round

The insulated cores of a multicore cable usually leave gaps when assembled together. Cable filler occupies these gaps to create a more circular profile before the inner sheath or outer jacket is extruded.

Core Features of Longtai PP Filler Rope

1. Uniform, pure color, free of impurity and contamination
2. Gentle stretching forms evenly‑meshed fibrillated network
3. Soft texture, high flexibility for easy bending during cable stranding
4. Twisted type with consistent twist count and stable outer diameter
5. Neat, tight winding without loose unwinding for smooth machine feeding
6. Non‑hygroscopic, rot‑proof & chemical‑resistant for long service life
7. Customizable denier, diameter, tube size, color and twist options available

Main Applications

Our polypropylene filler yarn is widely used for gap filling of various cable types:

• Power cables (low‑medium voltage)
• Control cables & signal cables
• Communication / telecommunication cables
• Also compatible for partial LSZH low‑smoke‑zero‑halogen cable assemblies

It effectively optimizes cable roundness, stabilizes internal cable core structure and improves overall cable finished quality.

Packaging Options

We offer multiple packing solutions according to roll weight & dimension:

1. Bare pallet packing: Rolls stacked directly on pallets and wrapped with stretch film
2. Small‑size rolls: 4 or 6 rolls packed inside woven bags, then loaded on pallets with stretch‑film wrapping
3. Large‑size twisted filler rope: Individual woven‑bag packing or bare pallet‑stack packing
