PA66 Nylon FR granules

High-Gloss Flame-Retardant PA66 Injection Molding Grade – Premium Engineering Plastic for Automotive and Industrial Applications

This high-performance polyamide 66 (PA66) material is specifically engineered for injection molding processes, offering exceptional surface finish, thermal stability, and flow characteristics. Designed without reinforcement, it delivers a smooth, glossy finish ideal for visible components in automotive interiors and exterior parts. The formulation ensures excellent dimensional accuracy, minimal warpage, and consistent mechanical properties across production runs—making it a preferred choice for manufacturers seeking both aesthetics and functionality.

Key features include outstanding melt flow index (MFI), high temperature resistance up to 150°C, superior impact strength, and inherent flame retardancy that meets international safety standards such as UL94 V-0. Its enhanced fluidity allows for complex mold designs while maintaining cycle time efficiency—a critical factor in high-volume manufacturing environments. Additionally, this grade offers improved chemical resistance compared to standard PA66, making it suitable for demanding applications in electrical enclosures, battery housings, and electronic device casings.

Beyond basic performance, the product supports customization based on customer-specific requirements—from adjusting melt viscosity for different processing conditions to incorporating specialized additives like UV stabilizers or anti-static agents. Whether you need an extrusion-grade variant for profile production or a tailored injection molding compound with enhanced rigidity or toughness, our team can develop a solution aligned with your project’s technical specifications. We analyze sample materials using advanced rheological testing and material characterization techniques to ensure optimal compatibility with your design needs.

Commonly used in automotive components such as dashboard trim, air vents, and under-hood connectors, this PA66 resin also finds application in household appliances including refrigerator liners, air conditioner housing, and motor enclosures. In industrial settings, it serves as a durable alternative for toolboxes, control panels, and mechanical assemblies exposed to elevated temperatures and mechanical stress. For electronics, its low smoke emission and flame-retardant nature make it ideal for mobile phone cases, router enclosures, and power bank housings where fire safety compliance is essential.

Users consistently report satisfaction with the balance of cost-effectiveness and performance this material provides. Many appreciate how the high gloss finish reduces post-processing steps like polishing or painting, thereby lowering overall production costs. Engineers note the ease of processing on standard injection molding machines and the reduced scrap rate due to stable flow behavior during filling stages. Customers working in regulated industries have praised the transparency of documentation regarding material certifications, including RoHS and REACH compliance.

Q: Is this PA66 suitable for outdoor use? A: Yes, when formulated with UV stabilizers, it maintains color and mechanical integrity even under prolonged sun exposure. Q: Can I request custom colors or additives? A: Absolutely—we offer tailored formulations including colorants, fillers, and flame-retardant systems to meet specific regulatory and aesthetic goals. Q: How does it compare to PA6 or PBT in terms of heat resistance? A: PA66 outperforms PA6 in thermal stability and offers better rigidity than most PBT grades at comparable cost points. Q: What makes this version flame-retardant? A: It contains halogen-free flame retardant additives that provide self-extinguishing properties without compromising processability or mechanical performance.
