BASF ULTRAMID A3X2G7 PA66 Resin

Physical Properties

• Density: Measured at 1.45 g/cc (0.0524 lb/in³) via ISO 1183, the higher glass fiber loading increases density, directly enhancing structural stiffness.
• Water Absorption: At 4.4–5.0% per ISO 62, reduced polymer matrix content lowers moisture sensitivity compared to lower-GF grades.
• Moisture Absorption at Equilibrium: Stable at 1.0–1.4% (ISO 62), suitable for long-term use in challenging mechanical environments.
• Viscosity Number: Maintaining 140 cm³/g (1.40 dl/g) per ISO 307, consistent molecular weight ensures reliable processing across reinforcement levels.
• Linear Mold Shrinkage:At 0.0045 cm/cm (0.0045 in/in), higher fiber content reduces shrinkage for tight dimensional control.
• Melt Flow Rate: Under ISO 1133, the flow rate of 43.5 g/10 min supports the production of large, high-strength components with balanced processability.

Polymer Properties:

• Base Material: Polyamide 66 (PA66)
• Reinforcement: 35% Glass Fiber
• Key Properties and Performance:
  
  • Flame Retardancy: This is the most crucial property. The material is formulated to inhibit or resist the spread of fire. 
  • Excellent Electrical Properties: The red phosphorus flame retardant system also provides outstanding electrical insulation. 
  • High Mechanical Strength and Stiffness: The 35% glass fiber reinforcement provides very high rigidity and tensile strength, suitable for structural parts that need to bear mechanical loads.
  • Thermal and Dimensional Stability: A3X2G7 has a high heat deflection temperature, which prevents parts from deforming at elevated temperatures.
