Q1: What is the primary application field for Hostatint Blue A-BTR 100-ST VP 5481?
A: This pigment paste is specifically developed for coloring polyolefin-based compounds, including PP and PE, in applications such as injection molding, blow molding, and extrusion—particularly where high thermal stability and good dispersion are required.
Q2: Is this color paste suitable for food-contact applications?
A: Hostatint Blue A-BTR 100-ST VP 5481 is formulated to meet general regulatory expectations for indirect food contact in polyolefins, subject to final compliance verification by the compounder or end user based on applicable regional requirements and processing conditions.
Q3: How should this paste be incorporated into polymer melts?
A: It is typically introduced via gravimetric or volumetric dosing directly into the extruder feed throat or hopper, or pre-compounded into masterbatches. Good melt mixing and sufficient residence time ensure optimal dispersion and color uniformity.
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 sources of heat. Avoid freezing, and ensure containers remain tightly closed when not in use to prevent moisture uptake or skin formation.
