The plastics industry relies heavily on high-performance colorants to achieve desired aesthetics and functionality. Pigment Red 48:1 (CAS 7585-41-3), also known as Barium Red 2B, is a favored organic pigment for numerous plastic applications, particularly in PVC and HDPE. As a leading chemical supplier and manufacturer, we understand the critical role this pigment plays and are committed to providing high-quality, cost-effective solutions for our B2B clients.

Why Pigment Red 48:1 is Ideal for Plastics

Pigment Red 48:1 offers a vibrant, yellowish-red shade that enhances the visual appeal of plastic products. Beyond its color, several key properties make it highly suitable for plastic formulations:

  • Excellent Migration Resistance: This is perhaps its most significant advantage in plastic applications, especially in flexible PVC. Pigment Red 48:1 resists migrating from the plastic matrix to the surface or into adjacent materials, ensuring consistent color and preventing surface contamination. This property is vital for products like artificial leather, films, and molded items.
  • Good Heat Resistance: With a heat resistance of around 200-240℃ for 5 minutes in PE, Pigment Red 48:1 can withstand common processing temperatures for many thermoplastics. This allows for its incorporation during extrusion or molding processes without significant degradation or color change.
  • Non-Blooming Characteristics: Related to its migration resistance, the pigment's tendency to not bloom ensures a clean surface finish for the plastic product.
  • Good Lightfastness: Rated around class 3 to 5, it provides adequate color stability for many indoor and some outdoor applications, though for extreme light exposure, alternative pigments might be considered.

Applications in PVC and HDPE

For PVC applications, such as artificial leather, profiles, and films, the non-migratory nature of Pigment Red 48:1 is invaluable. It ensures that the color remains locked in, providing durable and attractive finishes. When you are looking to buy Pigment Red 48:1 for PVC, you are opting for a pigment that guarantees a stable and aesthetically pleasing result.

In High-Density Polyethylene (HDPE), Pigment Red 48:1 is used for items like caps, closures, and containers. Its heat resistance allows it to be processed effectively with HDPE, providing a consistent red coloration. Manufacturers seeking a reliable supplier for their HDPE colorant needs will find our Pigment Red 48:1 to be a high-quality option.
