BASF ULTRAMID A3UG5 PA66 Resin

Physical Properties

• Bulk Density: Bulk density ranges from 0.500–0.800 g/cc (0.0181–0.0289 lb/in³), characterizing the material’s particle packing density in its raw state.
• Density: Via ISO 1183, the injection-molded sample density is 1.39 g/cc (0.0502 lb/in³), elevated by 25% glass fiber reinforcement compared to unfilled PA66.
• Equilibrium Moisture Absorption: Halogen-free flame retardant system ensures 1.1–1.5% moisture absorption (ISO 62) for stable electrical applications.
• Linear Mold Shrinkage: Recorded at 0.0040 cm/cm (0.0040 in/in) (method unspecified), glass fibers minimize shrinkage for precise fabrication.
• Melt Flow Rate: Tested per ISO 1133 at 275°C/5.00 kg, the flow rate of 34.75 g/10 min balances fluidity with structural rigidity for complex mold designs.

Polymer Properties:

• Base Material: Polyamide 66 (PA66)
• Reinforcement: 25% Glass Fiber
• Modification Features:
  
  • 25% Glass fiber reinforcement for enhanced mechanical strength.
  • Halogen-free flame retardance for safety and environmental compliance.

Applications:

The core strength of Ultramid® A3UG5 lies in its unique combination of high stiffness and strength from the glass fiber reinforcement and superior flame retardance from its halogen-free formulation.

This makes it an ideal material for safety-critical components in the automotive and electrical/electronics industries.

1. Electrical and Electronics Sector:
   • Its high CTI and UL 94 V-0 ratings make it an excellent material for applications requiring high electrical insulation and fire safety.
   • The halogen-free nature minimizes corrosion, making it safe for sensitive electronic components.
   • Examples: Electrical switch housings, connectors & relays, miniature circuit breakers (MCBs), and control units.
2. Automotive Industry:
   • The material’s high heat deflection temperature and mechanical strength allow it to perform reliably in high-temperature environments, such as those found under the hood.
   • Its resistance to chemicals, hot lubricants, and fuels is also a key advantage.
   • Examples: Connectors for electronic modules and sensors, engine covers, and under-the-hood components that require high strength and heat resistance.
3. Lighting Applications: Ultramid® A3UG5 is often used for LED lamp covers and lighting housings because of its excellent electrical properties and heat stability.
