High Pigment Brown Sand is a high-performance coloring product engineered to solve key drawbacks of traditional brown coloring materials in high-texture scenarios (e.g., outdoor wooden-style furniture, decorative building panels, luxury leatherette packaging): excessive pigment addition causing uneven color, higher costs, and rapid fading under UV exposure. Its core goal is to deliver natural, uniform high-saturation brown coloring with lower addition while ensuring processing fluidity and long-term color stability, providing tailored solutions for fields like furniture manufacturing, architectural decoration, and premium packaging that demand warm visual texture 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 brown 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 natural brown hiding power ≥0.67mg/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, with adjustable addition (1.7%-6.3%). It retains substrate chemical resistance no performance decay after 12 months in wood preservatives or packaging oils and suits PE outdoor wooden-style chairs, PP decorative building panels, and ABS luxury leatherette packaging boxes.
