BASF ULTRAMID A3WG7 HOT Sale PA66 Resin

Physical Properties

• Density: As per ISO 1183, the material has a density of 1.41 g/cc (0.0509 lb/in³), defining its mass – per – volume ratio.
• Water Absorption: In line with ISO 62, it absorbs 4.7 – 5.3% water, indicating its hygroscopic tendency in wet conditions.
• Moisture Absorption at Equilibrium: At 23°C and 50% relative humidity (R.H.) following ISO 62, it’s 1.4 – 1.8%, showing stable moisture uptake.
• Viscosity Number: According to ISO 307, it’s 145 cm³/g (1.45 dl/g), relating to the material’s internal friction in solution.
• Linear Mold Shrinkage: Measuring 0.0050 cm/cm (0.0050 in/in), it’s crucial for predicting size changes during molding.
• Melt Flow: Per ISO 1133, at 275 °C (527 °F) under 5.00 kg (11.0 lb) load, it’s 49.3 g/10 min, reflecting melt fluidity for processing.
