Nylon/polyamide 66 shortage: Information and alternatives

Find all information you need to survive the PA66 shortage.

Overcoming the nylon 66 shortage

Recently, the struggle to source a reliable supply of nylon/polyamide 66 (PA66) at an affordable price has become all too familiar for manufacturers. By now, most people in the industry understand the main cause of this struggle – insufficient global supply of the critical raw material Adiponitrile (ADN), the pre-cursor to hexamethylenediamine (HMDA).

Component manufacturers across a wide array of industries are left considering how to meet their production obligations with rising costs and PA66 shortages. At DSM, our portfolio of materials includes a number of polymers that can relatively easily replace PA66 while meeting the needs of the application.

Nylon/polyamide 66 alternatives

Akulon® PA6

With near-equivalent performance in stiffness and strength to PA66, and superior performance in toughness, processability, and heat aging resistance up to 200°C, PA6 is an ideal material for applications where parts are exposed to hot air (such as air intake manifolds and air ducts), exposed to oil (such as oil pans and oil filters), and parts with high requirements for surface appearance (such as pedals, door handles and power tool housings).

EcoPaXX® PA410

Ideal for applications where parts are exposed to water or glycol (such as for thermal management in automotive), PA410 is a high-performance bio-based polyamide. It demonstrates low moisture absorption and excellent chemical resistance, a high crystallization rate for fast and easy processing, and the highest melting point of all bio-based polyamides at up to 250°C.

Arnite® PBT

Ideal for electrical and lighting applications where peak temperatures are below 200°C (such as connectors, lighting frame bezels and LED components), PBT demonstrates excellent electrical properties, good dimensional stability, and high specific stiffness, with grades optimized to meet the toughest outgassing requirements at temperatures up to 200°C.

ForTii® PA4T/PPA

ForTii is a 4T semi-aromatic material that is significantly less dependent on HMDA for its production than 6T and 6I-based PPAs. ForTii provides high temperature resistance and excellent mechanical strength, while resisting oil and other aggressive engine fluids.

Stanyl® PA46

Ideal for electrical and lighting applications where peak temperatures are below 200°C (such as connectors, lighting frame bezels and LED components), PBT demonstrates excellent electrical properties, good dimensional stability, and high specific stiffness, with grades optimized to meet the toughest outgassing requirements at temperatures up to 200°C.
