What Makes Nylon 6 30% Glass-Filled a High-Performance Material?

Nylon 6 30% Glass-Filled combines strength, stability, and durability, making it a top choice for high-performance engineering applications.

Mechanical Strength and Rigidity

Nylon 6 30% Glass-Filled exhibits exceptional tensile and flexural strength compared to unfilled nylon. The embedded glass fibres reinforce the polymer matrix, making it capable of handling heavy mechanical loads without deformation. This high stiffness ensures reliable performance in structural or load-bearing components.

Thermal Stability and Heat Resistance

The glass reinforcement significantly improves thermal performance, allowing the material to maintain shape and mechanical strength at elevated temperatures. It offers a continuous service temperature of around 110 °C, making it ideal for automotive, electrical, and industrial environments where heat exposure is common.

Dimensional Stability and Creep Resistance

Glass fibres greatly reduce thermal expansion and moisture-related swelling, giving Nylon 6 GF30 excellent dimensional stability. It resists long-term deformation under static load (creep) and retains precision even in fluctuating conditions. This property is vital for parts requiring tight tolerances and consistent fit.

Wear, Abrasion, and Fatigue Resistance

This composite material excels in wear-intensive applications thanks to its fibre-reinforced surface. It endures repeated sliding, vibration, and impact without losing structural integrity. These traits make it ideal for gears, bushings, and bearing housings that demand long-term durability.

Chemical and Electrical Properties

Nylon 6 30% Glass-Filled maintains good resistance to oils, greases, fuels, and many solvents. Its low electrical conductivity and insulation capability make it suitable for electronic housings and connectors. Even under moisture or thermal stress, it maintains reliable electrical and chemical stability for demanding applications.

Benefits of Using Glass-Filled Nylon for CNC Machined Parts

Glass-filled nylon offers a unique combination of strength, rigidity, and wear resistance, attributes rarely found together in one engineering polymer. It’s ideal for parts exposed to repetitive motion, vibration, or stress. At XC Machining, we use advanced CNC equipment to precisely shape these materials while maintaining surface integrity and dimensional control.
Key advantages include:

  • Superior mechanical strength for load-bearing parts
  • High fatigue resistance under cyclic loads
  • Excellent wear and bearing properties for moving assemblies
  • Noise and vibration reduction for smoother performance

By leveraging the right machining parameters, XC Machining ensures that each Nylon 6 30% GF part we produce meets the highest industrial standards.

Benefits of Glass-Filled Nylon for 3D Printing Components

Glass-filled nylon is transforming the 3D printing industry by offering durability and strength far beyond standard polymers. XC Machining utilises advanced additive manufacturing technologies like Selective Laser Sintering (SLS) and Multi Jet Fusion (MJF) to create reinforced nylon parts that meet the highest mechanical and dimensional standards.

Key advantages include:

  • Superior strength and stiffness for structural or load-bearing components
  • Higher heat deflection temperature, ensuring stability under thermal stress
  • Exceptional wear and fatigue resistance for long-term durability
  • Improved dimensional accuracy and reduced warping during printing
  • Enhanced chemical and moisture resistance for harsh environments

By combining the right 3D printing parameters and post-processing methods, XC Machining ensures every glass-filled nylon component delivers metal-like performance with the agility and cost-efficiency of additive manufacturing.

Benefits of Glass-Filled Nylon for Injection-Molded Components

While standard nylons already provide a balance of hardness and toughness, they often fall short in heat and UV resistance. Adding glass fibres changes everything. The reinforcement enhances thermal stability, tensile strength, and wear resistance, making it suitable for high-stress or high-temperature environments. XC Machining uses premium formulations of glass-filled Nylon 66 and Nylon 6, such as:

  • Hylon Select N1013HL (13% GF Nylon 66)
  • Hylon Select N1033HL (33% GF Nylon 66)
  • Vydyne R533H (33% GF Nylon 66)
  • Zytel 77G33L (33% GF Nylon 6/12)
  • Zytel 70G33 (33% GF Nylon 66)
  • Minlon 10B40 (40% Mineral Reinforced Nylon 66)

Each formulation is carefully selected to achieve specific performance outcomes, such as rigidity, creep resistance, or temperature endurance, based on your application requirements.

Frequently Asked Questions

Nylon 6 30% Glass Filled

  • What is Nylon 6 30% Glass-Filled made of?

    Nylon 6 30% Glass-Filled is a composite material that combines Nylon 6 resin with 30% glass fibres. The glass reinforcement significantly enhances the polymer’s strength, rigidity, and dimensional stability, making it suitable for high-stress industrial applications. 

  • How does glass filling improve the performance of Nylon 6?

    The addition of glass fibres boosts mechanical strength, reduces thermal expansion, and improves heat resistance. This allows Nylon 6 GF30 to maintain its shape and precision under load or temperature variations, outperforming standard unfilled nylon. 

  • Can Nylon 6 30% Glass-Filled replace metal components?

    Yes, in many cases it can. Its high strength-to-weight ratio and excellent stiffness make it a reliable alternative to metal for structural, automotive, and machinery components—offering weight savings without sacrificing performance. 

  • Is Nylon 6 30% Glass-Filled suitable for outdoor or humid environments?

    While it resists moisture better than unfilled nylon, it’s still hygroscopic and can absorb some water over time. Proper conditioning and protective design measures can ensure long-term dimensional stability even in humid or outdoor conditions.
