The Philosophy of "Less is More": Why Phthalocyanine Pigments Dominate Plastics and Inks

In the balance between vivid aesthetics and industrial durability, Phthalocyanine Pigments stand out as one of the most successful discoveries in modern chemical engineering. As the absolute leaders in the blue and green spectrum, Hanwu Technology supplies premium Phthalocyanine Blue (PB15:3) and Green (PG7) series, helping countless downstream factories solve issues related to color instability and cost control.

1. Astonishing Tinting Strength: Minimal Dosage Required Compared to inorganic pigments, the core advantage of organic Phthalocyanine pigments lies in their “High Tinting Strength.” This means that in plastic granulation or ink formulation, only a minimal amount is needed to achieve deep, saturated shades. For Masterbatch manufacturers, using our high-concentration Phthalocyanine Blue not only reduces raw material costs per ton but also minimizes the risk of compromising the physical properties of the plastic due to excessive pigment loading.

2. Superior Heat Resistance and Migration Resistance In plastic processing (such as injection molding and film blowing), temperatures often reach 200°C or higher. Ordinary pigments tend to decompose or discolor under such heat, or cause color migration (bleeding) in the finished product. Hanwu Technology’s Phthalocyanine series undergoes rigorous thermal stability testing, ensuring hue stability in processing environments ranging from 240°C to 280°C. Furthermore, their excellent solvent resistance makes them ideal for packaging inks, preventing bleeding when in contact with contents like oils or alcohol.

3. Broad Application Compatibility Our product range covers various crystal structures, with a focus on:

• Phthalocyanine Blue 15:3 (Beta form): With a bright, greenish-blue shade, this is the most widely used general-purpose blue in the industry, suitable for the vast majority of polyolefins (PE/PP/PVC) and industrial coatings.
• Phthalocyanine Green 7: Featuring outstanding lightfastness and weather resistance, it resists fading even under long-term outdoor exposure, making it perfect for artificial turf, agricultural films, and outdoor plastic products.

Conclusion Choosing a pigment is not just about picking a color; it represents choosing safety and stability for your production process. Hanwu Technology is committed to providing global clients with high-performance organic pigments that offer consistent quality and excellent dispersibility.
