PA 11, also known as polyamide 11 or nylon 11, is a high-performance thermoplastic polymer derived from renewable sources, specifically castor oil. It offers excellent mechanical properties, including high tensile strength, impact resistance, and flexibility, making it ideal for producing durable and tough parts. PA 11 also has good chemical resistance and can withstand harsh environments, making it suitable for demanding applications in industries such as automotive, aerospace, and consumer goods. As a bio-polymer, PA 11 has a lower carbon footprint and is biodegradable, making it a more sustainable choice. Additionally, PA 11 is compatible with various manufacturing processes, including 3D printing, making it a versatile material for producing complex parts with excellent performance characteristics.

Properties and Characteristics

  1. High Strength: PA 11 exhibits excellent tensile strength and impact resistance, making it suitable for producing durable and functional parts.
  2. Flexibility: PA 11 has a relatively high flexibility, which allows for parts with complex geometries to be printed without breaking or cracking easily.
  3. Chemical Resistance: PA 11 is resistant to many chemicals, including oils, greases, and most solvents, making it suitable for applications that require exposure to various chemicals.
  4. Low Moisture Absorption: PA 11 has low moisture absorption compared to other polyamides, which helps maintain its mechanical properties and dimensional stability in humid environments.
  5. UV Resistance: PA 11 has good resistance to UV radiation, making it suitable for outdoor applications where exposure to sunlight is expected.
  6. Bio-based Material: PA 11 can be derived from renewable sources, making it a more sustainable option compared to other petroleum-based plastics commonly used in 3D printing.
  7. Excellent Layer Adhesion: PA 11 has good interlayer adhesion, resulting in strong and reliable 3D printed parts with minimal delamination between layers.
  8. Good Thermal Stability: PA 11 has a relatively high melting point, allowing for parts to withstand elevated temperatures without deformation or loss of mechanical properties.
  9. Easy to Post-Process: PA 11 can be easily machined, sanded, painted, or dyed after 3D printing, allowing for additional finishing or customization of printed parts.
  10. FDA-approved: PA 11 is approved by the U.S. Food and Drug Administration (FDA) for certain food contact applications, making it suitable for producing food-safe 3D printed objects.
