PA46 – Polyamide 46

PA46 (polyamide 46) is a technically advanced thermoplastic material belonging to the family of polyamides (nylons). It differs from other types such as PA6 or PA66 by having a higher content of amide groups, which gives it exceptional mechanical, thermal, and chemical properties. Due to its high crystallinity and thermal stability, PA46 is particularly suitable for demanding and thermally stressed applications.

Main properties:

• Outstanding thermal stability up to approx. 170–195 °C (continuous operating temperature)

• High mechanical strength and rigidity

• Excellent dimensional stability

• Good wear resistance, even at high temperatures

• Low friction and good self-lubrication without additives

• Good chemical resistance (oil, fuel, grease, organic solvents)

• Very low moisture absorption compared to other PA materials

• Excellent dielectric (insulating) properties

Typical applications:

• Automotive industry: engine components, bearing housings, spacers, gears, sliders, clutches

• Electronics: insulators, connectors, precision mechanical parts

• Industrial equipment: high-temperature bearings, guides, sliding elements, gears

• Chemical industry: components exposed to oil, fuels, and aggressive media
