Q1: What is the primary application field for Sanolin Red NBG?
A: Sanolin Red NBG is a high-performance organic pigment specifically developed for use in plastics, particularly in polyolefins such as PP and PE, where excellent heat stability, dispersion behavior, and color strength are required.
Q2: Is Sanolin Red NBG suitable for food-contact plastic applications?
A: Sanolin Red NBG is designed to meet stringent regulatory requirements for food-contact plastics in major markets. Its suitability depends on final formulation, processing conditions, and compliance verification by the compounder or end user against applicable local regulations.
Q3: How does Sanolin Red NBG perform under high-temperature processing?
A: This pigment exhibits good thermal stability, enabling reliable performance during typical polyolefin processing operations including injection molding and extrusion, without significant color shift or degradation.
Q4: What is the recommended dosage range for optimal coloration?
A: Dosage typically ranges from 0.1% to 2% by weight, depending on the desired shade intensity, polymer type, and processing method. It is generally used at low concentrations due to its high tinctorial strength and efficient dispersion characteristics.
Q5: Can Sanolin Red NBG be used in masterbatch formulations?
A: Yes, it is widely used in polyolefin-based masterbatches. Its excellent dispersibility and compatibility with common carrier resins support consistent color development and minimal filter pressure build-up during production.
