Q1: What is the primary application field for Sanodye Golden Orange RLW?
A: Sanodye Golden Orange RLW is a high-performance solvent-soluble pigment developed primarily for coloration of engineering plastics—especially polyolefins (PP, PE), ABS, PS, and thermoplastic elastomers—where excellent thermal stability, lightfastness, and dispersion characteristics are required.
Q2: Is this pigment suitable for food-contact plastic applications?
A: Sanodye Golden Orange RLW is not pre-qualified for direct food-contact use under global regulatory frameworks. Customers must conduct full regulatory assessment—including migration testing and compliance verification—based on their specific formulation, processing conditions, and target market requirements.
Q3: How should Sanodye Golden Orange RLW be dispersed in polymer melts?
A: Optimal dispersion is achieved using standard melt-compounding equipment (e.g., twin-screw extruders). Pre-dilution in a carrier resin or masterbatch preparation is recommended to ensure uniform distribution. Typical dosage ranges from 0.1% to 2% by weight, depending on desired shade strength and polymer system.
Q4: Does this pigment offer good resistance to heat during processing?
A: Yes—Sanodye Golden Orange RLW exhibits very good thermal stability, maintaining color integrity during standard injection molding and extrusion processes for polyolefins and styrenics. It is formulated to withstand typical processing temperatures up to approximately 260 °C for short residence times.
