DUPONT ZYTEL 79G13L PA66 Resin

Physical Properties

• Density: Tested via DAM and ISO 1183 for 13% glass-reinforced PA66; density is 1.21 g/cc (0.0437 lb/in³).
• Melt Density: At ≥263 °C (505 °F), melt density is 1.03 g/cc (0.0372 lb/in³), appropriate for glass-reinforced processing.
• Water Absorption: At 2.00 mm (0.0787 in) thickness, water absorption is 6.5%, per DAM and ISO 62 for reinforced materials.
• Moisture Absorption: For 2.00 mm (0.0787 in) samples, moisture absorption is 2.20%, following DAM and ISO 62 standards.
• Linear Mold Shrinkage, Flow: Flow direction shrinkage is 0.0040 cm/cm (0.0040 in/in) per DAM and ISO 294-4, 2577.
• Linear Mold Shrinkage, Transverse: Transverse shrinkage is 0.0080 cm/cm (0.0080 in/in), determined for glass-reinforced components.

Polymer Properties:

1. Base Material: Polyamide 66 (PA66)
2. Reinforcement:13% glass fiber
3. Modification Features:
   
   • Balanced Mechanical Properties: The 13% glass fiber reinforcement provides a good balance between strength and toughness.
   • Enhanced Tribological Properties: The “L” in the product name stands for lubricated. 
   • Good Heat Resistance: This material offers good thermal stability, with a heat deflection temperature (HDT) of approximately 220 °C under a load of 1.82 MPa (ISO 75-2).
   • Good Dimensional Stability: The low glass fiber content helps minimize shrinkage and warping during molding, providing dimensional stability and a smooth surface finish.
   • Good Chemical Resistance: Zytel 79G13L exhibits good resistance to a variety of chemicals, including oils, fuels, and greases,

Applications:

1. Automotive: Structural components like engine mounts, transmission cases, and wheel carriers requiring high strength-to-weight ratio.
2. Industrial Equipment: Reinforced machinery housings, industrial pipes, and load-bearing structures needing rigidity and wear resistance.
3. Consumer Goods: The good surface finish and balanced mechanical properties make it suitable for parts in consumer appliances and tools.
