Polyamide 12 (PA12)
Description (definition)
Polyamide 12 (PA12) is an engineering plastic produced by polymerization of lauric lactam. It is characterized by excellent chemical resistance, low water absorption and high flexibility. PA12 is particularly lightweight and is often used in applications where stability and durability are required, such as in the automotive and electrical industries and in 3D printing.
An example
A typical example is the use of PA12 in vehicle air ducts. Thanks to its low water absorption, it remains stable even under changing environmental conditions and ensures a long service life for the components.
What advantages does PA12 offer compared to other polyamides?
PA12 has significantly lower water absorption than PA6 or PA66, which improves its dimensional stability under humid conditions. It also offers excellent chemical resistance to oils, fuels and solvents. These properties make it ideal for use in demanding environments such as the automotive industry.
Which areas of application are typical for PA12?
PA12 is used in the automotive industry for fuel and brake lines, in electronics for cable sheathing and housings and in 3D printing for lightweight, stable components. PA12 is also used in medical technology, for example for flexible catheters and surgical instruments.
Is PA12 recyclable and how is it reused?
Yes, PA12 is recyclable. During mechanical recycling, PA12 waste is shredded and processed into granulate that can be used for new products. Thanks to its thermoplastic properties, PA12 remains stable even after repeated processing.
