尼龍 4.6 與普通尼龍相比，尼龍4.6的特點是剛性保存力強，耐蠕變性 好，在較寬的溫度範圍內，更耐熱老化，因此，尼龍4.6用於尼龍6 、尼龍66、POM 和PET在剛度、抗蠕變 、耐熱老化、疲勞強度 和耐磨性能方面所達不到要求的“較高的溫度領域”（80 -150 ℃）
Compared with ordinary nylon, nylon 4.6 is characterized by strong rigidity preservation, good creep resistance and better thermal aging resistance in a wide temperature range. Therefore, nylon 4.6 is used in the "higher temperature field" (80 -150℃) where nylon 6, nylon 66, POM and PET cannot meet the requirements in terms of rigidity, creep resistance, thermal aging resistance, fatigue strength and wear resistance.
