Built for High-Tenacity Yarns. Engineered for Tire Cords and Safety Belts

Consistent IV, Low Shrinkage – For Critical Technical Textile Applications

Product Description

HanLink’s High Modulus Low Shrinkage (HMLS) PET chips are specifically developed for high-tenacity technical textiles such as industrial yarns, tire cord fabrics, and seat belts. Through precise polymerization and solid-state polycondensation (SSP) processes, our chips achieve high intrinsic viscosity, low carboxyl end group content, and excellent crystallization behavior—ensuring stable spinning and consistent downstream performance.

 

Product Features

1. Uniform Particle Size: Precisely controlled granulation ensures smooth melt filtration and excellent spinning performance.
2. Low Oligomer Content: Reduces fume generation and surface residue, improving product cleanliness.
3. Stable IV: Intrinsic viscosity variation within ±0.005, minimizing pressure fluctuation and yarn breakage.
4. Low Heat Shrinkage: Superior thermal stability enables excellent dimensional control during processing.
5. High Strength & Modulus: Excellent mechanical properties, especially under tension and high-stress conditions.
6. Compatible with High-Speed Spinning: Optimized melt flow and crystallinity support modern high-efficiency spinning lines.

 

Applications

HanLink HMLS chips are widely used in applications requiring high strength, heat resistance, and dimensional stability, including:

🔹 Tire Cord Fabrics – High stability under heat and pressure

🔹 Seat Belts& Lifting Straps – High tenacity, low elongation, enhanced safety

🔹 Conveyor Belts & V-Belts – Strong, wear-resistant, and long-lasting

🔹 Coated Fabrics – Excellent dimensional stability under thermal processing

🔹 High-Tenacity Industrial Yarn – Suitable for twisting, coating, and composite uses
