High Pigment Blue Sand is a high-performance coloring product engineered to solve key drawbacks of traditional blue coloring materials in high-visibility scenarios: excessive pigment addition causing uneven color, higher costs, and rapid fading under strong UV exposure. Its core goal is to deliver vivid, uniform high-saturation blue coloring with lower addition while ensuring processing fluidity and long-term color stability, providing tailored solutions for fields like outdoor navigation, consumer electronics, and marine engineering that demand strong visual distinction and reliable color retention.
For carriers, it uses modified resins compatible with diverse substrates, categorized into three types: PE-based (MFR 9-17g/10min) for polyethylene products, PP-based (MFR 11-19g/10min) for polypropylene, and ABS-based (MFR 14-22g/10min) for ABS engineering plastics. All carriers achieve over 98% compatibility with their respective substrates, preventing blue pigment agglomeration, surface streaks, or delamination during molding, while preserving substrate mechanical properties—e.g., PE retains ≥95% tensile strength, ABS maintains ≥92% impact strength.
Molded products feature uniform vivid blue (hiding power ≥0.68mg/cm² for dark substrates like gray PP) and stable performance: no pigment migration after 7 months at 60℃/90% humidity, ≤5% mechanical fluctuation (-38℃ to 120℃). It works steadily at standard processing temperatures (PE injection 175-215℃, PP extrusion 185-225℃, ABS injection 200-240℃), with adjustable addition (1.6%-6.2%). It retains substrate chemical resistance (no performance decay after 12 months in marine saltwater or electronic cleaning solvents) and suits PE outdoor directional signs, PP electronic device shells, and ABS marine equipment parts.
