Polyester Chip Series Product Overview
1. Cationic Polyester Chips
Enhanced Dyeability & Color Brilliance
Specially modified polymers enable superior cationic dye absorption, achieving vibrant hues with exceptional color fastness. Ideal for producing deep-tone fabrics in automotive textiles, premium apparel, and home furnishings.
Key Features:
- 30% higher dye uptake vs. conventional polyester
- Wash/light fastness: Grade 4-5 (ISO 105 standards)
- Low oligomer content (<0.5%)
2. Flame-Retardant Polyester Chips
Built-in Fire Safety
Incorporates phosphorus-based compounds for self-extinguishing properties (LOI ≥28). Meets EN11612, NFPA 701, and GB/T 5455 standards for industrial protective gear, curtains, and transportation interiors.
Performance Highlights:
- UL94 V-0 certification achieved
- Maintains fiber strength (≥85% retention post-treatment)
- Halogen-free formulation
3. Semi-Dull Polyester Chips
Sophisticated Matte Finish
Controlled TiO₂ content (0.3-0.5%) delivers reduced surface reflectivity for premium matte aesthetics. Perfect for luxury packaging films, anti-glare textiles, and high-end sportswear.
Advantages:
- Gloss level: 15-20 GU (60° measurement)
- Consistent spinnability (CV% <1.8)
- Recyclable (GRS-certified options available)
4. High-Gloss Polyester Chips
Brilliant Surface Optics
Ultra-transparent formulation with crystallinity optimization creates mirror-like reflectivity. Optimized for LED lighting films, metallic yarns, and holographic packaging materials.
Technical Superiority:
- Light transmittance: ≥89% (ASTM D1003)
- Haze: ≤2%
- Thermal stability: ≤1% IV drop @280°C
