Q1: What is the primary chemical class of Sanodye Orange 2B?
A: Sanodye Orange 2B is an azo-based organic pigment, specifically designed for high chroma and clean orange hue in demanding polymer applications.
Q2: Is this pigment suitable for food-contact plastics?
A: Sanodye Orange 2B is not intended for direct food-contact applications. It is formulated for general-purpose industrial and decorative plastics where regulatory compliance for food contact is not required.
Q3: How does Sanodye Orange 2B perform under thermal processing conditions?
A: This pigment demonstrates good thermal stability suitable for standard melt-processing temperatures of polyolefins and styrenics, though extended residence at elevated temperatures may affect shade intensity.
Q4: What are typical dosage levels when incorporating Sanodye Orange 2B into plastics?
A: Dosage depends on formulation requirements and desired opacity or transparency, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in the final polymer matrix.
