Features Of HD-S Pigment

  1. High thermal stability up to 280 °C, enabling compatibility with high-temperature polymer processing.

  2. Excellent lightfastness and weather resistance (rated ISO 105-B02: 7–8), ensuring long-term color retention outdoors.

  3. Low migration tendency in PVC, polyolefins, and engineering plastics, supporting regulatory compliance for food-contact applications.

  4. Optimized particle size distribution (D50 ≈ 0.35 μm) for superior dispersion and gloss enhancement in masterbatches.

  5. Heavy-metal-free formulation compliant with REACH, RoHS, and FDA 21 CFR §178.3297.

Typical Applications Of HD-S Pigment

  1. Color concentrates for injection-molded automotive interior parts.

  2. UV-stable pigmentation of exterior building profiles (PVC window frames, cladding).

  3. High-clarity colorants for transparent PET packaging films.

  4. Pigmented masterbatches used in medical-grade polypropylene components.

  5. Decorative laminates and HPL (high-pressure laminate) surface layers.
