Celanese Zytel 70G35HSL PA66 Resin

Physical Properties

• Density: Measured using injection-molded samples in accordance with DAM and ISO 1183, the density is 1.41 g/cc (0.0509 lb/in³).
• Melt Density: At a temperature of 295 °C (563 °F), the melt density is 1.24 g/cc (0.0448 lb/in³).
• Water Absorption: After 24h immersion (DAM, sim. ISO 62), water absorption is 1.1%; at 2.00 mm thickness (same standards), it’s 5.5%.
• Moisture Absorption: At 2.00 mm (0.0787 in) thickness, moisture absorption is 1.70% (DAM; sim. to ISO 62).
• Viscosity Number: Determined with 96% sulfuric acid per ISO 307, 1157, 1628, the viscosity number is 145 cm³/g (1.45 dl/g).
• Linear Mold Shrinkage: Per DAM/ISO 294-4/2577, injection-molded plaques have 0.0030 cm/cm (flow) and 0.011 cm/cm (transverse) linear mold shrinkage.

Polymer Properties:

• Base Material: Polyamide 66 (PA66)
