Nylon rods are available in various colors, including blue, white, and black, and different types of products have different applications.
Nylon 6 (White Nylon Rod): This material possesses superior overall performance, including mechanical strength, stiffness, toughness, mechanical damping, and wear resistance. These characteristics, combined with good electrical insulation and chemical resistance, make Nylon 6 a "general-purpose" material used in the manufacture of mechanical structural parts and maintainable components.
Nylon 66 (Cream-colored Nylon Rod): Compared to Nylon 6, it has better mechanical strength, stiffness, heat resistance, wear resistance, and creep resistance, but lower impact strength and mechanical damping. It is very suitable for machining on automatic lathes.
Nylon 4.6 (Red-brown Nylon Rod): Compared to ordinary nylon, Nylon 4.6 is characterized by strong rigidity retention, good creep resistance, and better heat aging resistance over a wider temperature range. Therefore, Nylon 4.6 is used in "higher temperature fields" (80-150°C) where Nylon 6, Nylon 66, POM, and PET cannot meet the requirements in terms of stiffness, creep resistance, heat aging resistance, fatigue strength, and wear resistance.
Nylon 66+GF30 (Black Nylon Rod): Compared to pure Nylon 66, this nylon is reinforced with 30% glass fiber, resulting in improved heat resistance, strength, stiffness, creep resistance, dimensional stability, and wear resistance. It has a higher maximum allowable operating temperature.
Nylon 66+MOS2 (Gray-black Nylon Rod): This nylon is added with molybdenum disulfide. Compared to Nylon 66, its rigidity, hardness, and dimensional stability are improved, but its impact strength is reduced. The grain formation effect of molybdenum disulfide improves the crystalline structure, resulting in improved load-bearing and wear resistance properties.
