PA4.6 Multi-filament Yarn

Polyamide 46 is a high-crystalline polymer, formed by the polycondensation of 1,4-diaminobutane and adipic acid. High crystallinity contributes significantly to high-performance yarn characteristics, such as superior heat resistance at elevated temperature (melting point is 290°C), increased stiffness, tensile strength, and modulus. This provides the requested properties of yarn in industrial and automotive applications like tire cord fabrics, conveyor and power transmission systems, automotive tubes, airbags, or sewing yarns. The highly ordered crystalline domains make PA46 yarns more resistant to mechanical deformation and surface wear, which is crucial for parts subject to high friction and speed. Additionally, a highly dense molecular structure increases the chemical resistance of the PA46 yarn to various aggressive substances, fuels, greases, oils, improves creep resistance, and improves its dimensional stability.
