In the global plastics industry, color consistency, thermal stability, and regulatory compliance are non-negotiable. Among all inorganic blue pigments, Pigment Blue 29 (Ultramarine Blue) continues to be one of the most trusted choices for plastic masterbatch manufacturers, polymer compounders, and bulk buyers worldwide.
As a Pigment Blue 29 manufacturer and exporter, Ultramarine Blue India supplies high-performance ultramarine pigments designed specifically for plastic masterbatch applications, where dispersion quality, heat resistance, and batch-to-batch consistency directly impact production efficiency and final product quality.
This detailed guide explains what Pigment Blue 29 is, why it is widely used in plastic masterbatch, and how to select a reliable Pigment Blue 29 exporter from India for domestic and international supply.
What Is Pigment Blue 29?
Pigment Blue 29, commonly known as Ultramarine Blue, is an inorganic sodium aluminosilicate pigment containing sulfur. It is produced through a controlled calcination process using natural minerals, making it structurally stable and chemically inert for most industrial applications.
Unlike organic blue pigments, Pigment Blue 29 offers:
- Excellent thermal resistance
- Strong alkali stability
- Non-bleeding behavior
- High opacity and brightness
- Cost-effective performance for bulk plastic applications
Because of these properties, Pigment Blue 29 is extensively used in plastic masterbatch manufacturing, where pigments must survive high processing temperatures without color degradation.
