PA66
Polyamide 66 has a more compact molecular structure compared to Polyamide 6. This is due to stronger hydrogen bonding and better alignment of the molecular chains. As a result, Polyamide 66 offers enhanced resistance to compression, matting, and stain penetration, making it stronger and more durable than Polyamide 6.

PA66 is less sensitive to moisture absorption than PA6, making it better suited for high-temperature applications. 4KTEC® PA66 offers high impact resistance and exceptional mechanical performance.

The product range includes materials reinforced with glass fibers and mineral fillers and can be customized with UV/light stabilization, impact modification, laser-marking capability, heat resistance, flame-retardant properties, and various other additives.

4KTEC® PA66 formulations can be tailored to meet specific market requirements. It is a fully recyclable material that retains its properties even after regrinding and reprocessing.
