Color Masterbatch For PA

‌Color Masterbatch for PA/Nylon‌ Specialized pigment concentrates engineered for Polyamide resins (PA6, PA66, PA12, etc.), delivering uniform dispersion and color stability under high-temperature processing. ‌Key Features‌ ‌High-Temperature Resistance‌ Withstands processing up to ‌300–320°C‌ (critical for PA’s melting point). Prevents pigment degradation during injection molding or extrusion. ‌Moisture Control‌ Includes ‌desiccants‌ to counter PA’s hygroscopic nature (pre-drying essential). Reduces bubble formation and surface defects. ‌Compatibility‌ Carrier resins match PA chemistry (e.g., PA6/PA66-based carriers). Compatible with reinforced grades (glass/carbon fiber-filled PA). ‌Performance Enhancements‌ UV stabilizers for outdoor applications (e.g., automotive parts). Options: Heat-stable organics, metallics, or specialty pigments. ‌Applications‌ ‌Automotive‌: Engine covers, connectors, fuel systems. ‌Industrial‌: Gears, bearings, electrical housings. ‌Consumer‌: Power tool housings, sports equipment. ‌Fibers‌: Textiles, fishing lines, carpets. ‌Processing Guidelines‌ ‌Dosage‌: 1–5% (varies by opacity/effect). ‌Drying‌: Mandatory pre-drying (≥80°C for 4+ hours) to <0.1% moisture. ‌Equipment‌: Compatible with injection molding, extrusion, fiber spinning. ‌Specialty Grades‌ ‌Fiber Masterbatches‌: Low-viscosity for fine denier yarns. ‌Flame-Retardant (FR)‌: For electrical components. ‌Food-Contact‌: FDA/EC-compliant formulations. ‌Note‌: PA masterbatches require stricter process controls (vs. PS/ABS) due to temperature sensitivity and moisture absorption. Proper dispersion prevents ‌streaking‌ or ‌mechanical weakening‌ in final parts.
