Nylon 6 (PA6)

Properties of Nylon 6 (PA6)

RADILON® S HSX 100 NT is a heat-stabilized, high-viscosity PA6 designed for injection moulding, offering superior mechanical strength, rigidity, and good resistance to heat ageing. Zytel® 7301 NC010 is a toughened, unreinforced Nylon 6 formulation that delivers enhanced impact performance and thermal resistance.

• Tensile Strength: 70–85 MPa
  
  
• Flexural Modulus: 2500–3000 MPa
  
  
• Elongation at Break: 40–80 %
  
  
• Density: ~1.13–1.15 g/cm³
  
  
• Heat Deflection Temperature (1.8 MPa): ~80–90 °C
  
  
• Melting Point: 220–225 °C
  
  
• Impact Strength (notched, 23 °C): 5–7 kJ/m²
  
  
• Water Absorption (24 hr): 1.2–1.5 %
  
  
• Excellent fatigue and abrasion resistance
  
  

These properties give PA6 an ideal balance of mechanical performance, heat tolerance, and durability for complex injection-moulded designs.

Applications of Nylon 6 (PA6)

With its superior strength-to-weight ratio, PA6 is widely used across multiple industries where performance and durability are critical.

• Automotive: Gears, bearings, brackets, under-hood components, and cooling system parts
  
  
• Industrial Equipment: Bushings, pulleys, machine guards, and wear plates
  
  
• Electrical & Electronics: Connectors, cable ties, switches, and insulating housings
  
  
• Consumer Goods: Power tool housings, appliance components, and sports gear
  
  
• Aerospace: Lightweight mechanical housings and vibration-resistant fittings
  
  
• Medical & Healthcare: Handles, structural casings, and non-contact moving parts
  
  

At Amuse3D, we work with high-performance PA6 grades such as RADILON® S HSX 100 NT by RadiciGroup and Zytel® 7301 NC010 by Celanese, both optimized for injection moulding applications. These grades deliver the durability and dimensional stability needed for load-bearing, high-precision components across automotive, electronics, and industrial sectors.

Machining & Finishing Options

Amuse3D’s injection moulding process for Nylon 6 materials ensures tight tolerances and consistent mechanical strength across production batches.

• Optimized melt temperature (240–270 °C) for complete polymer flow
  
  
• Mould temperature control (70–90 °C) for improved crystallization
  
  
• Drying cycle: 80 °C for 3–4 hours to minimize moisture pickup
  
  
• Surface finishes from high-gloss to matte or textured
  
  
• Colour matching, glass-fiber reinforcement, and UV stabilization available
  
  
• Precision cooling and gating to reduce warpage and internal stress
  
  

Our experienced team fine-tunes every parameter to achieve high-performance components that retain mechanical integrity and dimensional accuracy.

Comparison to Alternatives

• Versus Nylon 66 (PA66): PA6 offers better impact resistance and easier processing, though PA66 provides slightly higher temperature performance.
  
  
• Versus POM (Delrin): Nylon 6 offers better toughness and thermal resistance, while POM provides lower friction and better dimensional stability in dry conditions.
  
  

For applications requiring strength, flexibility, and cost-effectiveness, Nylon 6 is a proven choice.
