Q1: What is the primary application field for Hostafine Blue B2G 30 Color Paste?
A: Hostafine Blue B2G 30 is a high-performance pigment dispersion designed primarily for coloring polyolefins—especially PP and PE—in injection molding, blow molding, and extrusion applications. It is widely used in technical parts, packaging, and consumer goods where consistent blue hue, excellent thermal stability, and low plate-out are required.
Q2: Is this color paste suitable for food-contact plastics?
A: Hostafine Blue B2G 30 is formulated to meet general requirements for food-contact applications in polyolefins, subject to compliance with applicable regional regulations. Its suitability depends on final formulation, processing conditions, and end-use compliance verification—including migration testing under intended use conditions.
Q3: How should the color paste be incorporated into polymer melts?
A: The paste is typically introduced via gravimetric or volumetric dosing directly into the feed throat of extruders or injection molding machines. Pre-blending with base resin is not required, but uniform dispersion is ensured through standard melt-mixing conditions compatible with polyolefin processing temperatures.
Q4: Does this product offer good resistance to thermal degradation during processing?
A: Yes—Hostafine Blue B2G 30 is engineered for enhanced thermal stability in polyolefin processing. It maintains color consistency and minimizes pigment decomposition or gas evolution even under extended residence times and elevated melt temperatures typical of high-output operations.
