Polyamide 6.6T (PA 6/6/T)
Description (definition)
Polyamide 6.6T (PA 6/6/T) is a high-performance copolyamide formed by the polymerization of hexamethylenediamine (C6), adipic acid (C6) and terephthalic acid (T). It combines the thermal stability and strength of PA66 with the improved chemical resistance and reduced moisture absorption of aromatic components. This combination makes PA 6/6/T particularly suitable for demanding technical applications where resilience and dimensional stability are crucial.
An example
One example of PA 6/6/T is its use in high-temperature seals and housings for industrial machinery. Thanks to its thermal stability and chemical resistance, it can be used long-term in environments with extreme conditions.
What are the advantages of PA 6/6/T over conventional PA66?
PA 6/6/T offers improved chemical resistance, particularly to acids and oils, and absorbs less moisture. As a result, it remains dimensionally stable even under humid conditions and is better suited for precise technical components.
Can PA 6/6/T withstand high temperatures?
Yes, PA 6/6/T is heat-resistant and retains its mechanical properties even at temperatures of over 200 °C. This property makes it ideal for applications near heat sources or in thermally stressed environments.
Which applications benefit from PA 6/6/T?
PA 6/6/T is used in industrial machinery, electrical parts and technical components that have to withstand high loads. It is also suitable for applications that require resistant properties when exposed to chemicals, such as pump and valve components.
