Halogen Free Flame Retardant PP Fibrillated Filler Yarn, also known as HFFR PP Filler Yarn (Not Twist), is a high-performance, environmentally friendly cable filler material produced from premium polypropylene with advanced halogen-free flame retardant additives. Through a specialized fibrillation process, it forms a strong mesh structure that provides excellent filling, rounding, and mechanical reinforcement for cables while delivering superior flame retardancy and low smoke emission. This non-twisted fibrillated yarn is the ideal choice for high-grade flame-retardant cables requiring compliance with strict environmental and fire-safety standards.
Key Features and Advantages
- Halogen-Free Flame Retardancy: AOI ≥28% and halogen content ≤1000 ppm ensure low smoke and toxicity during combustion.
- High-Strength Mesh Structure: Fibrillated design delivers excellent tensile strength and breaking elongation for enhanced cable roundness and mechanical stability.
- Low Shrinkage: Shrinkage <6% at 100°C for 30 minutes maintains dimensional stability during cable extrusion and long-term service.
- Excellent Processability: Lightweight, uniform, and easy to handle in high-speed stranding lines.
- Eco-Friendly: Halogen-free formulation meets global environmental regulations while maintaining cost-effectiveness.
Main Applications
HFFR PP Fibrillated Filler Yarn is widely used for filling and rounding in:
- Power cables and control cables
- Mine cables and industrial cables
- Telecommunication and data cables
- High-grade flame-retardant special wires and cables
It effectively fills gaps between conductors, improves cable roundness, increases overall tensile strength, and enhances fire safety performance.
