Physical Properties
- Density: As per the ISO 1183 standard, the density of the material is 1.36 g/cc in the metric system and 0.0491 lb/in³ in the English system.
- Water Absorption: Based on the ISO 62 standard, the water absorption rate of the material is in the range of 5.2 – 5.8 %, applicable for both metric and English units.
- Moisture Absorption at Equilibrium: At a condition of 23°C and 50% relative humidity (R.H.), following the ISO 62 standard, the moisture absorption at equilibrium is between 1.5 – 1.9 % for both measurement systems.
- Viscosity Number: The viscosity number of the material is 145 cm³/g in the metric unit, which is equivalent to 1.45 dl/g.
- Linear Mold Shrinkage: The linear mold shrinkage is 0.0055 cm/cm in the metric system and 0.0055 in/in in the English system.
- Melt Flow: According to the ISO 1133 standard, under a load of 5.00 kg (11.0 lb) and at a temperature of 275 °C (527 °F), the melt flow rate of the material is 54.4 g/10 min for both metric and English descriptions of this property.
Polymer Properties:
- Base Material: Polyamide 66 (PA66)
- Reinforcement: 30% Short Glass Fiber
- Modification Features
- Glass fiber heightens rigidity and strength
- Good heat resistance
- Stable dimensions
- Injection – moldable
- Moderate impact resistance
Applications:
Given its enhanced properties, ULTRAMID A3EG6 PA66 is commonly used in similar but more demanding applications than A3EG5.
- Automotive: Under-the-hood parts that are exposed to extreme heat and mechanical stress, such as engine mounts, intake manifolds, and radiator end caps.
- Industrial: High-load applications like high-performance gears, bearing cages, and structural parts where strength and rigidity are critical.
- Electrical/Electronics: Components requiring both mechanical robustness and thermal stability, such as high-voltage connectors and heavy-duty switchgear housings.
