Polyamide (PA 6 / PA 66 / PA 6G): Engineering Plastics Built for Performance
Polyamide (PA 6 / PA 66 / PA 6G) is one of the most versatile engineering plastics widely used in mechanical, electrical, and industrial applications. Known for its remarkable strength, wear resistance, and chemical stability, polyamide materials combine performance with cost-efficiency, making them an excellent alternative to metal components.
At Nordio Plastic, as one of the trusted Polyamide suppliers in UAE, we import premium-grade PA 6, PA 66, and PA 6G sheets and rods manufactured by Röchling Germany—a global leader in high-performance polymers. Our commitment is to supply industries across the UAE and GCC with polyamide materials that meet exacting international standards, ensuring consistency, durability, and long service life under demanding conditions.
What is Polyamide?
Polyamide (commonly referred to as Nylon) is a semi-crystalline thermoplastic polymer composed of recurring amide bonds. Depending on its molecular structure, polyamide is available in several grades such as PA6, PA66, and PA6G, each offering distinct mechanical and chemical properties.
- Polyamide 6 (PA6): Offers high toughness, excellent damping properties, and good machinability.
- Polyamide 66 (PA66): Provides higher heat resistance, rigidity, and dimensional stability than PA6.
- Polyamide 6G (PA6G): A cast version of PA6 that offers superior wear resistance and minimal internal stress, suitable for large parts and complex machining.
Key Applications of Polyamide
Due to its strength-to-weight ratio and versatile properties, polyamide is widely utilized across various industries:
Industrial and Mechanical Engineering
- Gears, pulleys, bearings, and bushings
- Slide guides, rollers, and wear pads
- Conveyor and automation system components
Automotive and Transportation
- Under-the-hood parts (such as fuel lines, connectors, and housings)
- Structural and noise-dampening components
- Lightweight replacements for metal parts
Electrical and Electronics
- Electrical insulators and mounting parts
- Cable ties and terminal blocks
- Housings for connectors and enclosures
Construction and Manufacturing
- Support elements, spacers, and profiles
- Components exposed to mechanical stress and vibration
- Custom machined parts in OEM production
Food and Packaging Industry
- PA6G materials can be supplied in food-grade quality upon request
- Used for rollers, cutting guides, and processing machinery parts
Properties of Polyamide (PA 6 / PA 66 / PA 6G)
Polyamide materials are valued for their outstanding mechanical balance and reliability in both dry and lubricated operating conditions. Each grade—PA6, PA66, and PA6G—offers a combination of strength, stiffness, and impact resistance suitable for demanding mechanical parts.
Mechanical Properties
- High tensile and compressive strength: Ideal for load-bearing parts subjected to cyclic stress.
- Excellent impact resistance: Maintains structural integrity even under sudden shocks or vibration.
- Good fatigue strength: Performs consistently in dynamic or repetitive motion applications.
- Low friction and abrasion resistance: Extends service life in sliding and wear-intensive environments.
Thermal and Chemical Properties
- Operating temperature range: -30°C to +120°C depending on grade.
- Thermal stability: PA66 and PA6G exhibit minimal creep at elevated temperatures.
- Resistance to oils, greases, and fuels: Suitable for automotive and industrial lubrication systems.
- Limited resistance to strong acids and alcohols: Recommended to avoid prolonged chemical exposure outside rated compatibility.
Physical Properties
- Density: Approx. 1.13–1.15 g/cm³.
- Moisture absorption: Moderate (lower for PA66 and PA6G), influencing dimensional accuracy.
- Hardness: Between 75–85 Shore D, depending on grade and condition.
- Color availability: Natural, black, and blue (for cast nylon – PA6G).
Electrical Properties
- Polyamide exhibits good dielectric strength and insulation performance, making it suitable for electrical housings, cable glands, and terminal boards. However, moisture absorption can slightly reduce insulation properties in humid environments—an important factor to consider during design and installation.

Important Considerations When Buying Polyamide
When selecting the right grade of polyamide, it is essential to consider the operational environment and mechanical requirements. Here are a few technical factors to evaluate:
- Temperature range: For parts exposed to heat, PA66 or PA6G are more suitable.
- Friction and wear: PA6G excels in sliding or load-bearing applications.
- Moisture absorption: PA66 absorbs less moisture, maintaining better dimensional stability.
- Machining precision: Cast polyamide (PA6G) offers the lowest internal stress levels, allowing large stable components to be machined without distortion.
- Compliance needs: Food-grade or electrical insulation requirements can dictate the appropriate material choice.
Our technical team at Nordio Plastic provides assistance with grade selection, machining feasibility, and dimensional optimization — ensuring the perfect balance between performance and cost.
