Physical Properties

• Density: As per ISO 1183, the density of the material is 1.48 g/cc (0.0535 lb/in³), which represents the mass per unit volume of this substance.
• Water Absorption: According to ISO 62, the material exhibits a water absorption rate ranging from 4.8 – 5.4%, indicating its capacity to take in water.
• Moisture Absorption at Equilibrium: At 23°C and 50% relative humidity (R.H.) as per ISO 62, the moisture absorption at equilibrium is 1.2 – 1.6%, showing its stable moisture content under these conditions.
• Viscosity Measurement: Based on the Viscosity Number determined by ISO 307, the viscosity measurement value of the material is 136, reflecting its internal resistance to flow.
• Linear Mold Shrinkage: With a linear mold shrinkage of 0.0060 cm/cm (0.0060 in/in), this property is important for predicting dimensional changes during the molding process.
• Melt Flow: Per ISO 1133, at a temperature of 275 °C (527 °F) and a load of 5.00 kg (11.0 lb), the melt flow rate of the material is 44.4 g/10 min, indicating its fluidity in the molten state for processing.

Polymer Properties:

• Base Material: Polyamide 66 (PA66)
• Reinforcement: Mineral and Glass Fiber (specific ratio not clear)
• Key Features and Properties:
  
  • Excellent dimensional stability and low warpage: The combination of spherical glass beads and mineral fillers significantly reduces anisotropy (directional shrinkage).
  • High stiffness and rigidity: Provides sufficient stiffness for structural and load-bearing applications.
  • Good surface finish: Parts molded from chopped glass fibers often leave a rough or fibrous texture. This makes it ideal for aesthetically pleasing parts.
  • Good heat resistance: This material exhibits excellent thermal stability, making it suitable for applications in medium to high temperature environments.
  • Excellent flow: The filler combination provides improved flow properties compared to some high-glass fiber grades, making it easier to mold thin-walled and complex parts.
