High Pigment Green Sand is a high-performance coloring product engineered to solve key drawbacks of traditional green 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 green coloring with lower addition while ensuring processing fluidity and long-term color stability, providing tailored solutions for fields like landscape engineering, food packaging, and agricultural supplies that demand natural visual harmony and reliable color retention.
For carriers, it uses modified resins compatible with diverse substrates, categorized into three types: PE-based (MFR 8-16g/10min) for polyethylene products, PP-based (MFR 10-18g/10min) for polypropylene, and PET-based (MFR 12-20g/10min) for polyester materials. All carriers achieve over 98% compatibility with their respective substrates, preventing green pigment agglomeration, surface streaks, or delamination during molding, while preserving substrate mechanical properties—e.g., PE retains ≥94% tensile strength, PET maintains ≥90% elongation at break.
Molded products feature uniform vivid green (hiding power ≥0.65mg/cm² for dark substrates like gray PP) and stable performance: no pigment migration after 6 months at 60℃/90% humidity, ≤5% mechanical fluctuation (-35℃ to 115℃). It works steadily at standard processing temperatures (PE injection 170-210℃, PP extrusion 180-220℃, PET blow molding 240-270℃), with adjustable addition (1.5%-6%). It retains substrate chemical resistance (no performance decay after 12 months in food-grade solvents or agricultural fertilizers) and suits PE outdoor landscape chairs, PP food packaging boxes, and PET agricultural mulch films.
