• Automotive industry: Used for gears, bearings, housings, and other parts needing strength, wear, and heat resistance.
• Electronics: Insulators, connectors, and components needing electrical and thermal stability.
• Textiles: Fibers for clothing, carpets, and technical fabrics with strong abrasion resistance.
• Industrial machinery: Sliding plates, sprockets, gears, and bearings requiring low friction and wear durability.
• High mechanical strength and stiffness: Excellent tensile strength and rigidity for demanding uses.
• Outstanding wear resistance: Very resistant to abrasion, ideal for friction
• exposed parts.
• Good thermal resistance: With a higher melting point (~255 °C) than PA6, it performs well in high
• temperature environments.
• Good chemical resistance: Resistant to oils, fuels, and several solvents.
• Glass fiber reinforcement options: Variants like PA6.6 GF25 offer enhanced strength, thermal stability, and wear resistance.
• High moisture absorption: Being hygroscopic, PA6.6 can absorb environmental moisture, impacting dimensional and mechanical stability.
• Processing challenges: High melting temperature requires controlled processing and thorough pre
• drying.
