Pigments Powder for Masterbatch Applications

Partnering with Masterbatch Producers

Deqing Demi Pigment Technology Co., Ltd. is a key supplier to the global masterbatch industry. We provide the high-intensity inorganic powders required to create cost-effective color concentrates. Our production facility focuses on the "wetting-out" characteristics of the pigment, ensuring that masterbatch manufacturers can achieve high throughput and excellent dispersion quality. We understand that the consistency of the pigment powder directly dictates the quality of the final masterbatch and the efficiency of the "let-down" process.

Masterbatch Industry Usage

• Mono-Masterbatches: High-purity single-pigment concentrates.
• Tailor-Made Color Concentrates: Multi-pigment blends for specific brand colors.
• Additive Masterbatches: Combined color and UV/antistatic packages.
• Liquid Masterbatches: Dispersion of pigments in liquid carriers for specialty dosing systems.

Masterbatch Grade Specifications

Operational Features for Compounding

• Maximum Loading: Low oil absorption allows for higher pigment-to-resin ratios in the concentrate.
• Efficient Wetting: Surface treatments reduce the mixing time and energy required for full encapsulation.
• Consistent Color Strength: Standardized tinting strength ensures the masterbatch has the same "let-down" value every time.
• Low Volatility: Prevents the formation of bubbles or "silver streaks" during the masterbatch pelletizing process.

• Q: What is the benefit of low FPV in masterbatch pigments?

  A: A low Filter Pressure Value indicates that the pigment has very few agglomerates, meaning it will not clog the fine mesh filters in fiber or film extrusion lines.

• Q: Can these pigments be used in engineering plastics masterbatches?

  A: Yes, our high-temperature stable series is suitable for use in masterbatches based on PA, ABS, or PET carrier resins.

Quality Verification for Concentrates

We test our pigments by producing a 50% concentration masterbatch in-house. This allows us to verify the dispersion and color development in a real-world scenario before the product is approved for shipping.

Formula Optimization: We provide technical data to help masterbatch formulators choose the right wetting agents and waxes to maximize the pigment loading and improve the flow properties of the final concentrate.

The Science of Let-Down Consistency

In masterbatch science, the "let-down ratio" is critical. We use CIELab data to ensure that the relationship between pigment concentration and color intensity is linear. This allows masterbatch producers to provide their customers with precise dosing instructions. We provide the spectral reflectance data for the concentrated pigment, ensuring that even at high dilutions, the color remains within the specified ΔE tolerance, maintaining the integrity of the final product's appearance.
