PA6 Filled Reinforced is an engineering-grade glass fiber reinforced polyamide 6 compound enhanced with selected mineral fillers such as talc, calcium carbonate, mica, wollastonite, and barium sulfate. Designed for applications demanding low warpage, high thermal endurance, and superior electrical safety, this material offers an optimized balance of stiffness, dimensional stability, and OEM-level formulation flexibility.
Product Overview
PA6 Filled Reinforced is a high-performance polyamide 6 compound combining glass fiber reinforcement with functional mineral fillers, including talc, calcium carbonate, mica, wollastonite, and barium sulfate.
This multi-filler system is engineered to fine-tune stiffness, thermal stability, and dimensional control beyond conventional glass fiber reinforced PA6. By synergizing fibrous reinforcement with plate-like and particulate fillers, the material effectively reduces molding warpage, improves surface stability, and enhances electrical insulation behavior.
The formulation is especially suitable for complex structural components, thin-wall electrical parts, and heat-exposed assemblies where both mechanical reliability and long-term dimensional accuracy are critical. Developed for OEM manufacturers, this grade supports consistent processing performance, scalable production, and customized property balancing for specific applications.
Key Material Advantages
Low Warpage for Dimensional Precision
By combining glass fiber reinforcement with mineral fillers such as talc and mica, the material achieves controlled shrinkage behavior and reduced anisotropy during cooling. This hybrid reinforcement approach significantly minimizes warpage, especially in large, thin-wall, or geometrically complex molded parts.
High Heat Resistance
PA6 Filled Reinforced maintains structural integrity under continuous elevated temperatures, making it suitable for under-hood automotive parts and heat-adjacent electrical components.
High Glow-Wire Performance
Engineered to meet demanding glow-wire ignition and flammability requirements, supporting safe use in electrical and electronic applications.
High CTI (Comparative Tracking Index)
Excellent resistance to electrical tracking enhances long-term safety in high-voltage and moisture-exposed environments.
OEM-Level Customization
Formulations can be tailored for fiber content, heat resistance, flame retardancy, color, and processing behavior to match exact project requirements.
Filled Reinforcement System – Engineering-Level Material Design
Unlike standard glass fiber reinforced PA6, this filled reinforced system incorporates carefully selected mineral fillers to achieve targeted performance optimization.
• Talc and mica contribute to improved stiffness, heat resistance, and warpage control, particularly in large or flat molded parts.
• Calcium carbonate enhances dimensional stability and cost-performance balance for high-volume OEM production.
• Wollastonite improves mechanical reinforcement efficiency while supporting thermal stability and surface integrity.
• Barium sulfate increases density uniformity and enhances electrical insulation performance in specific applications.
Through controlled filler ratio design and dispersion technology, the compound achieves a stable balance between rigidity, processability, and electrical safety — making it suitable for demanding engineering and electrical environments.
