Melting temperature, rate of crystallization, and crystallinity of PA4,6 are higher than that of PA6 and PA6,6 polymers. Therefore, PA4,6 gives excellent properties at high temperatures such as high stiffness, high creep resistance, high thermal stability, good toughness, and high fatigue resistance. In addition, PA4,6 shows better chemical resistance to acidic salts, methanol, mineral salts, oils, and greases. Excellent mechanical properties at high temperatures, low friction, excellent resistance to wear, and excellent chemical resistance of PA4,6 make this polymer a good candidate for the broad range of technical applications such as electrical, electronic, and automotive industries.
