Q1: What is the primary application field for Sanodye Red RLW?
A: Sanodye Red RLW is a high-performance, solvent-stable azo pigment specifically developed for coloring polyolefin masterbatches and thermoplastic compounds, with strong suitability for injection molding and extrusion processes.
Q2: Is Sanodye Red RLW suitable for food-contact plastics?
A: Sanodye Red RLW is designed to meet stringent regulatory requirements for food-contact applications in polyolefins, subject to compliance with applicable regional regulations and final formulation validation by the compounder or converter.
Q3: How does Sanodye Red RLW perform under thermal processing conditions?
A: This pigment exhibits excellent thermal stability, maintaining consistent color strength and hue during standard polyolefin processing temperatures up to approximately 280 °C, with minimal risk of degradation or gas-phase staining.
Q4: What is the typical dosage range when using Sanodye Red RLW in PP or PE masterbatches?
A: Dosage depends on the desired shade intensity and base polymer, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in masterbatch formulations.
