DUPONT ZYTEL EFE1068 PA66 Resin

Physical Properties

• Density: Tested via DAM and ISO 1183 with injection-molded samples; density is 1.14 g/cc (0.0412 lb/in³) for this unreinforced PA66.
• Melt Density: At ≥263 °C (505 °F), melt density measures 0.950 g/cc (0.0343 lb/in³), suitable for processing applications.
• Water Absorption: At 2.00 mm (0.0787 in) thickness, water absorption is 8.5%, following DAM and ISO 62 methodology.
• Moisture Absorption: For 2.00 mm (0.0787 in) samples, moisture absorption is 2.80%, per DAM and similar to ISO 62 standards.
• Linear Mold Shrinkage: Both flow and transverse directions show 0.015 cm/cm (0.015 in/in) per DAM and ISO 294-4, 2577 for injection molding.

Polymer Properties:

• Base Material: Polyamide 66 (PA66)
• Key Features and Properties:
  • Exceptional High Flow: Zytel EFE1068 has an extremely high melt flow rate (MFR), significantly higher than standard PA66 grades.
  • Fast Cycle Time: The high flow and rapid solidification of this material lead to a substantial reduction in molding cycle time.
  • Good Mechanical Properties: Despite its high flow, the material still offers good mechanical properties.
  • Good Surface Finish: The material’s high flow and smooth processing result in parts with an excellent surface finish, reducing the need for secondary finishing operations.

Applications:

• Electrical and Electronics Industry: The high flow and fast cycle time make this grade a perfect fit for complex and small electrical components.
• Automotive Industry: The high flow and fast cycle time are leveraged for small, complex parts in automotive applications.
• Precision Gears and Mechanisms: Ideal for molding small, complex gears and other precision mechanisms found in consumer devices and appliances.
