Nylon is a widely used synthetic polymer, known for its strength, durability, and chemical resistance. In CNC machining, nylon offers versatility across various applications. Here’s a streamlined overview of the key nylon types and their properties.
Nylon 6 (PA 6): Lightweight and Tough
Nylon 6 is synthesized from caprolactam and is known for its tensile strength, abrasion resistance, and elasticity. However, it absorbs moisture, which may impact dimensional stability. With a melting point of 428°F (220°C), it’s ideal for:
- Gears and bushings
- Automotive engine covers and intake manifolds
- Electrical insulators and connectors
Nylon 6/6 (PA 66): Superior Strength and Wear Resistance
PA 6/6, made from adipic acid and hexamethylenediamine, offers higher tensile strength, reduced moisture absorption, and a melting point of 500°F (260°C). Applications include:
- High-performance mechanical components
- Glass-filled options for enhanced strength
Nylon 6/12 (PA 6/12): Moisture-Resistant
With alternating monomers, PA 6/12 absorbs less moisture, making it dimensionally stable. Common uses:
- Fuel lines and electrical sheathing
- Zippers and outdoor equipment
Nylon 11 (PA 11): Sustainable and Impact Resistant
Derived from castor oil, PA 11 is eco-friendly and excels in flexibility, UV resistance, and low-temperature impact resistance. It’s often used in:
- Sporting goods
- Snap-fit parts and hinges
Nylon 12 (PA 12): Chemically Resistant
PA 12 is a linear aliphatic polyamide with excellent chemical resistance and dimensional stability. Applications include:
- Medical components and automotive fuel systems
- Enclosures and fixtures
Enhancing Nylon Properties: Fillers
Fillers such as glass and minerals improve strength and dimensional stability. Popular options include:
- Glass-filled nylon for mechanical strength (e.g., Vydyne R533H)
- Mineral-filled nylon for stiffness (e.g., Minlon 10B40)
- UV-stabilized and impact-modified nylons
Choosing the Right Nylon in CNC
