Polyamide 11 (PA11)
Description (definition)
Polyamide 11 (PA11) is a bio-based engineering plastic obtained from castor oil. It is known for its flexibility, chemical resistance and good mechanical properties, even at low temperatures. PA11 is often used in applications where sustainability and performance are equally important, for example in the automotive and electronics industries and in medical devices.
An example
A typical example is the use of PA11 in the manufacture of fuel lines. Its chemical resistance to oil and fuels and its flexibility make it ideal for use in demanding environments.
What are the advantages of PA11 over other polyamides?
PA11 offers greater flexibility and better resistance to chemicals and moisture compared to PA66 or PA6. It also remains mechanically stable at low temperatures and is a more sustainable alternative to petroleum-based polyamides due to its bio-based origin.
What are the typical applications for PA11?
PA11 is often used in the automotive industry for fuel lines, air lines and cable sheathing. In electronics, it is used in insulating components, and in medical technology it is used for flexible catheters and surgical devices.
Is PA11 recyclable?
Yes, PA11 is recyclable. Mechanical recycling enables PA11 waste to be reprocessed in granulate form for new applications. In addition, bio-based production helps to reduce the ecological footprint.
