Q1: What is the primary chemical nature of 1XS Pigment?
A: 1XS Pigment is an organic pigment dispersion formulated for high chromatic strength and excellent lightfastness. It is neither a dye nor a metallic oxide-based pigment, but rather a stabilized, surface-modified organic colorant designed for compatibility with polar polymer matrices.
Q2: Is 1XS Pigment suitable for food-contact plastics?
A: 1XS Pigment is not pre-approved for direct food-contact applications. Its suitability depends on final regulatory assessment by the formulator, including migration testing and compliance verification against applicable regional frameworks (e.g., FDA 21 CFR, EU Plastics Regulation). It is commonly used in non-food packaging, industrial components, and decorative applications where regulatory clearance is not required.
Q3: How should 1XS Pigment be incorporated into thermoplastic resins?
A: For optimal dispersion, 1XS Pigment is typically introduced during compounding—either via side-feeding or masterbatch dilution. Pre-drying is not required, but thorough melt mixing at recommended processing temperatures ensures uniform distribution without agglomeration or streaking.
Q4: Does 1XS Pigment exhibit good thermal stability during extrusion or injection molding?
A: Yes, 1XS Pigment demonstrates robust thermal stability up to typical processing temperatures for polyolefins and engineering thermoplastics (e.g., ≤260°C for short residence times). Significant color shift or decomposition is not observed under standard industrial processing conditions.
Q5: What is the recommended dosage range for achieving target color intensity?
A: Dosage depends on formulation requirements and desired opacity, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the base polymer. Optimal loading should be determined empirically via lab-scale trials to balance color strength, dispersion quality, and cost efficiency.
