Q1: What types of polymer systems is Colanyl Oxide Yellow BV 100 compatible with?
A: Colanyl Oxide Yellow BV 100 is formulated for use in a broad range of thermoplastics, including polyolefins (PP, PE), PS, ABS, and engineering polymers such as PA and PBT. It demonstrates good thermal stability and dispersion behavior during standard melt processing.
Q2: How should this color paste be incorporated into the base polymer?
A: The paste is typically introduced via gravimetric or volumetric dosing directly into the extruder feed throat or upstream of the melting zone. Pre-blending with carrier resin or masterbatch dilution may be used to ensure uniform distribution, especially in high-precision applications.
Q3: Is Colanyl Oxide Yellow BV 100 suitable for food-contact or medical-grade applications?
A: This product is not pre-qualified for regulated food-contact or medical applications. Customers must conduct full regulatory evaluation—including migration testing and compliance verification—based on their specific formulation, processing conditions, and end-use requirements.
Q4: What is the recommended dosage range for achieving target shade intensity?
A: Dosage depends on the base polymer, desired chroma, and processing method, but typical usage generally ranges from 0.1% to 2% by weight. Lower concentrations are often sufficient due to the high tinctorial strength of the oxide yellow pigment system.
