1.Product Description
Pigment Red 48:1 (P.R. 48:1) is an innovative high-performance azo-based barium salt lake organic pigment, redefining yellowish red coloration for industrial applications with its exceptional migration resistance and heat stability—setting it apart from Pigment Red 48-1 (calcium salt) and other red lake pigments. Unlike ordinary red pigments that easily migrate in plastic formulations, suffer from poor heat stability, or have low color fastness, our P.R. 48:1 features a proprietary diazotization-coupling and precision barium salinization process, delivering three client-centric advantages: a stunning vivid yellowish red hue, exceptional migration resistance, and superior heat stability—solving manufacturers’ pain points of color bleeding, fading during high-temperature processing, and uneven color distribution.
Crafted with advanced low-temperature diazotization, coupling technology and high-purity barium salinization purification process, Pigment Red 48:1 boasts a uniform fine powder particle structure (0.14–0.20 μm) and optimized dispersion performance, ensuring seamless integration into plastic melts, solvent-based inks, and rubber formulations, even in high-speed and high-temperature processing. Its distinct vivid yellowish red hue offers a warmer, more saturated alternative to conventional red pigments, elevating product aesthetics. Additionally, it is 100% compliant with REACH, RoHS, and EINECS 231-494-8, non-toxic, heavy metal-free, and suitable for diverse high-end industrial applications, including PVC artificial leather, latex gloves, and high-end packaging printing.
Engineered for long-term reliability, Pigment Red 48:1 boasts Grade 5 lightfastness and thermal stability up to 200℃ (short-term processing), retaining its vivid yellowish red hue even after high-temperature processing and moderate outdoor exposure. Its excellent solvent resistance (resistant to esters, xylene, ketones, and common organic solvents) and superior migration resistance (optimized via barium salt modification) effectively prevent color bleeding in plastic and ink formulations—outperforming calcium salt-based P.R. 48-1 in anti-migration performance. With broad compatibility, high tinting strength, and long-term durability, it is a versatile one-stop solution for plastic, ink, and rubber industries, delivering consistent, vibrant yellowish red results that set your products apart—combining performance, durability, and compatibility in one high-quality pigment.

3.Product Application
Pigment Red 48:1 is a versatile, high-performance organic pigment, tailored to meet the specific needs of plastic, ink, rubber, and coating industries with its exceptional migration resistance, vivid yellowish red hue, and superior heat stability. Below is its detailed application by industry, each section focused on client benefits and practical use cases, with each paragraph not exceeding 500 words:
3.1 Plastic Coloring
Pigment Red 48:1 is a top choice for high-end plastic coloring, especially suitable for PVC (soft and hard), PE, PP, and ABS plastics, as well as PVC artificial leather. Its excellent compatibility with plastic melt formulations ensures uniform dispersion during injection molding and extrusion, eliminating streaking or color unevenness. Compared to Pigment Red 48-1, it features superior migration resistance, effectively avoiding color bleeding in soft PVC applications and ensuring consistent color in long-term use. With high tinting strength, only 0.9% loading is needed to achieve standard color depth, significantly reducing raw material costs. Ideal for plastic parts, PVC artificial leather, and high-end plastic stationery, it delivers a vivid, consistent yellowish red hue that retains its vibrancy even after high-temperature processing and long-term use.
3.2 Printing Inks
Perfect for solvent-based printing inks, including gravure, offset, and flexographic inks, Pigment Red 48:1 is widely used in high-end tobacco labels, wine labels, and food packaging printing. Its excellent dispersion capability ensures smooth ink flow, eliminating sedimentation even in high-speed printing, and it can be well combined with ketone, acrylic, and polyurethane resin systems. The vivid yellowish red hue delivers sharp, bright prints with good gloss, enhancing the visual appeal of packaging products. Its superior solvent resistance and migration resistance prevent color fading or bleeding in ink formulations, ensuring prints retain their vibrancy for a long time. With reliable performance and high color fastness, it is a preferred choice for high-end label and packaging printing.
3.3 Rubber Products
Applicable to rubber products, including latex gloves, rubber seals, and rubber toys, Pigment Red 48:1 features good compatibility with rubber formulations and excellent processing stability. It disperses uniformly in rubber during vulcanization, ensuring consistent color distribution without affecting rubber mechanical properties. Its superior heat stability (stable below 200℃) ensures no color fading during vulcanization, outperforming Pigment Red 48-1 in high-temperature rubber processing. The vivid yellowish red hue adds a bright, appealing color to rubber products, while its non-toxic, eco-friendly properties comply with global rubber product safety standards, making it suitable for latex gloves and consumer-facing rubber products.
3.4 Industrial Paints & Stationery
Pigment Red 48:1 is suitable for industrial paints (metal protective paints, wood paints) and stationery coloring (color pencils, crayons). Its good dispersion in paint formulations ensures uniform color and good coverage, while its vivid yellowish red hue delivers an eye-catching finish. In stationery, it features good color fastness, resisting fading and smudging, making it ideal for high-quality color pencils and crayons. Additionally, it can be blended with other pigments to create custom red shades, expanding its application scope. Its superior migration resistance and heat stability make it a reliable choice for industrial paint and stationery manufacturers, delivering consistent, high-performance results.
