Q1: What is the primary application area for Sanolin Blue EHRL Pigment?
A: Sanolin Blue EHRL Pigment is specifically developed for coloration of polyolefins—especially injection-molded and extruded parts—where high thermal stability, excellent dispersion, and good lightfastness are required. It is widely used in automotive interior components, consumer goods, and industrial packaging.
Q2: Is Sanolin Blue EHRL suitable for food-contact applications?
A: Sanolin Blue EHRL Pigment is designed to meet general requirements for food-contact plastics under applicable global regulatory frameworks. Its suitability for specific food-contact use must be confirmed based on the final formulation, processing conditions, and regional compliance requirements—including migration testing where applicable.
Q3: How does Sanolin Blue EHRL perform under high-temperature processing?
A: This pigment exhibits very good thermal stability, enabling reliable performance during standard polyolefin processing—including temperatures up to 280 °C for short residence times. It maintains color strength and shows minimal degradation or gas-phase volatilization under typical extrusion and injection molding conditions.
Q4: What is the recommended dosage range for optimal color development?
A: Dosage depends on the desired shade intensity, polymer type, and processing method. It is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—and offers excellent tinting strength and batch-to-batch consistency when properly dispersed.
