Description

Poly(Disperse Red 1 Methacrylate) is a functional polymer dye synthesized by polymerizing the methacrylate derivative of the classic azo dye, Disperse Red 1. This product matters for its ability to impart permanent, stable red coloration to polymeric materials with excellent compatibility and processability. It is primarily needed by manufacturers in the plastics, specialty coatings, and advanced material sectors seeking to create intrinsically colored polymers with enhanced light and migration fastness.

Application

• Masterbatch Production: For coloring polyolefins (PP, PE), polystyrene, ABS, and engineering plastics.
• Synthetic Fiber Spinning: Incorporation into polyester, nylon, or acrylic fibers during polymerization or melt spinning for deep, uniform coloration.
• Optical Materials & Filters: Manufacturing of colored optical lenses, light filters, and laser-sensitive polymeric components.
• Specialty Coatings & Inks: Formulation of high-performance, weather-resistant industrial coatings and printing inks for plastics.
• 3D Printing Filaments: Coloring of photopolymer resins or thermoplastic filaments (PLA, ABS) for consistent, vibrant results.
• Security & Authentication Features: Use in traceable pigments for brand protection, currency, or secure document applications.
