Q1: What types of polymer systems is Colanyl Blue B2G 131 compatible with?
A: Colanyl Blue B2G 131 is formulated for use in polyolefins—including polyethylene (PE) and polypropylene (PP)—as well as certain engineering thermoplastics. It demonstrates good thermal stability during standard melt processing conditions and is commonly used in injection molding, extrusion, and blow molding applications.
Q2: How should this color paste be incorporated into a polymer formulation?
A: The paste is typically added directly to the base polymer using standard masterbatch dilution or gravimetric feeding systems. For optimal dispersion, it is recommended to pre-mix with a portion of the carrier resin before full compounding. Avoid excessive shear or prolonged residence time at elevated temperatures to preserve color integrity.
Q3: Is Colanyl Blue B2G 131 suitable for food-contact applications?
A: This product is designed for industrial and non-food-contact applications unless explicitly approved under applicable regional food-contact regulations. Customers intending to use it in food-contact articles must verify compliance with local regulatory requirements and consult Clariant’s technical support for application-specific documentation.
Q4: What is the typical dosage range for achieving target shade intensity?
A: Dosage depends on the polymer type, desired depth of shade, and processing conditions. In most polyolefin applications, effective concentrations generally range from 0.1% to 2% by weight relative to the base resin—typically used at low concentrations due to its high tinting strength.
