Nylon, also known as polyamide in Chinese and Polyamide (PA) in English, is a general term for thermoplastic resins with repeating amide groups—[NHCO]—on the main molecular chain. Its naming is determined by the specific number of carbon atoms in the synthetic monomer. It was invented by the American chemical industrial company DuPont chemist Carothers and his research team.
The nylon series is an important type of engineering plastic. This product has a wide range of applications, covering almost every field, and is one of the most widely used varieties among the five major engineering plastics.
1: Nylon 6 (White): This material has excellent comprehensive performance, including mechanical strength, rigidity, toughness, mechanical shock absorption, and wear resistance. These characteristics, combined with good electrical insulation and chemical resistance, make Nylon 6 a "general-grade" material used in the manufacture of mechanical structural parts and maintainable parts.
2: Nylon 66 (Cream): Compared to Nylon 6, it has better mechanical strength, rigidity, heat resistance, and wear resistance. However, its impact strength and mechanical shock absorption decrease, making it very suitable for automatic lathe machining.
3: Nylon 4.6 (Red Brown): Compared to ordinary nylon, Nylon 4.6 has stronger rigidity retention, good creep resistance, better heat aging in a wider temperature range. Therefore, Nylon 4.6 is used in the "higher temperature range" (80 - 150 °C) where Nylon 6, Nylon 66, POM, and PET do not meet the requirements in terms of rigidity, creep resistance, heat aging, fatigue strength, and wear resistance.
4: Nylon 66+GF30 (Black): Compared to pure Nylon 66, this nylon is reinforced with 30% glass fiber, which improves its heat resistance, strength, rigidity, creep resistance, dimensional stability, and wear resistance. It has a higher maximum allowable use temperature.
5: Nylon 66+MOS2 (Gray Black): This nylon is added with molybdenum disulfide. Compared to Nylon 66, its rigidity, hardness, and dimensional stability are improved, but the impact strength decreases. The effect of molybdenum disulfide on crystal grain formation improves the crystalline structure, enhancing the material's load-bearing and wear resistance.
II: Cast Nylon Sheet, also known as MC Nylon: The English name is Monomer Casting Nylon, and the Chinese name is monomer cast nylon. It is widely used due to its light weight, high strength, self-lubrication, wear resistance, corrosion resistance, insulation, and other unique properties. It is a widely used engineering plastic that is almost ubiquitous in all industrial fields.
Main Characteristics of Nylon Sheets
