Polyamide 4.6 (PA4/6)
Description (definition)
Polyamide 4.6 (PA4/6) is a high-performance polyamide made from the monomers tetramethylenediamine (C4) and adipic acid (C6). It is characterized by exceptionally high heat resistance, excellent mechanical strength and low creep tendency. These properties make PA4/6 particularly suitable for applications in the automotive, electrical and household appliance industries where reliability at high temperatures is required.
An example
A typical example is the use of PA4/6 in engine components such as timing belt pulleys or air intake pipes. Thanks to its high thermal stability, it can withstand long-term temperatures of over 150 °C.
What advantages does PA4/6 offer over other polyamides?
PA4/6 has a higher heat resistance and rigidity than polyamides such as PA6 or PA66. It also offers better mechanical strength at high temperatures and is therefore particularly suitable for high-performance applications.
How is PA4/6 used in the automotive industry?
In the automotive industry, PA4/6 is used for heat-resistant parts such as engine components, air intake pipes and cooling system elements. Its low creep tendency and dimensional stability ensure a long service life, even under extreme conditions.
What applications are there for PA4/6 in household appliances?
In household appliances, PA4/6 is used for heat-resistant parts such as pump housings, valves or components in dishwashers. Its strength and resistance to chemical cleaning agents ensure a long service life.
