Polyamide 6 (PA6)
Description (definition)
Polyamide 6 (PA6) is a thermoplastic produced by the polymerization of caprolactam. It is characterized by high toughness, good chemical resistance and thermal stability. PA6 is often used in applications where flexibility and impact resistance are required, such as tanks, hoses or housings in the automotive industry.
Example
A typical example is the use of PA6 in the manufacture of air intake manifolds in vehicles. Thanks to its combination of lightness, stability and chemical resistance, PA6 can increase the performance and efficiency of modern cars while saving costs at the same time.
What advantages does PA6 offer compared to other polyamides?
PA6 offers an excellent combination of flexibility and resilience. It has a higher toughness than PA66, making it more suitable for applications that require impact resistance and elasticity. In addition, PA6 is less expensive and easier to process, making it the preferred choice for many industrial applications.
In which industries is PA6 frequently used?
PA6 is used in the automotive industry for parts such as tanks, hoses and engine covers. In the textile industry, it is used as a base material for hard-wearing synthetic fibers, which are used for outdoor clothing or technical textiles, for example. PA6 is also used in electronics and mechanical engineering for durable housings and components.
Is PA6 recyclable and how is it recycled?
Yes, PA6 can be recycled. Mechanical recycling involves shredding and re-granulating PA6 waste, while chemical recycling breaks PA6 down into its original monomers, which can be re-polymerized. The recycling process contributes to sustainability and reduces dependence on fossil raw materials.
