Q1: What is the primary application field for Hostatint Oxide Yellow A-CR 100?
A: This color paste is specifically developed for coloring polyolefin-based plastics—especially PP and HDPE—in applications requiring excellent thermal stability, good dispersion, and consistent hue under processing conditions such as injection molding and extrusion.
Q2: Is this product suitable for food-contact plastic applications?
A: Hostatint Oxide Yellow A-CR 100 is formulated with inorganic oxide pigments and is designed to meet general regulatory expectations for indirect food contact applications in polyolefins; however, final compliance depends on the complete formulation, processing parameters, and applicable regional regulations—users must conduct their own due diligence and verification.
Q3: How should this color paste be incorporated into polymer melts?
A: It is typically introduced via gravimetric or volumetric dosing directly into the feed throat of an extruder or injection molder, or pre-blended with base resin using a high-shear mixer. Good dispersion is achieved at standard processing temperatures for polyolefins without requiring additional dispersing aids.
Q4: What are the key handling and storage recommendations?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and moisture. Avoid freezing. Stir gently before use if phase separation occurs during prolonged storage, as this paste contains a non-volatile carrier system optimized for polymer compatibility.
