1：Nylon 6(white): The material has the best comprehensive properties including mechanical strength, stiffness, toughness, mechanical shock absorption and wear resistance. These characteristics, combined with excellent electrical insulation and chemical resistance, make nylon 6 a "universal grade" material, used in the manufacturing of mechanical structural parts and maintainable parts.
2：Nylon 66(cream color): Compared with nylon 6, its mechanical strength, stiffness, heat and wear resistance, creep resistance are much better, but the performances of impact strength and mechanical shock absorption are decreased, which is very suitable for automatic lathe machining.
3：Nylon 4.6 (reddish-brown): Compared with ordinary nylon, nylon 4.6 is characterized by strong rigidity preservation, good creep resistance, and better thermal aging resistance within a wide temperature range. Nylon 4.6 is used in the "higher temperature field" in which nylon 6, nylon 66, POM and PET can’t meet the requirements of stiffness, creep resistance, thermal aging, fatigue strength and wear resistance.
4：Nylon 66+GF30 (black): Compared with pure nylon 66, this kind of nylon is added 30% glass fiber to enhance its heat resistance, strength and stiffness. Creep resistance, dimensional stability, wear resistance and other performances have been improved. Its maximum allowable using temperature is relatively higher.
5：Nylon 66+MOS2 (gray black): This nylon is filled with molybdenum disulfide. Compared with nylon 66, its rigidity, hardness and dimensional stability are improved, but the shock resistance strength is decreased. The grain formation effect of molybdenum disulfide improves the crystal structure so that the bearing capacity and wear resistance of the material are all improved.
