Introduction
Nylon (Nylon), also known as polyamide in Chinese, is a general term for thermoplastic resins with repeat amide groups—[NHCO]—on the main chain of molecules. Its naming is determined by the specific number of carbon atoms in the synthetic monomer. It was invented by Carothers, a chemist at the American chemical industry company DuPont, and his research team.
The nylon series is an important engineering plastic. This product is widely used and covers almost every field, making it one of the most widely used varieties among the five major engineering plastics.
Varieties of nylon sheets
1: Nylon 6 (white): This material has excellent comprehensive properties, including mechanical strength, rigidity, toughness, mechanical shock absorption, and wear resistance. These characteristics, combined with good electrical insulation ability and chemical resistance, make Nylon 6 a "general-purpose" material used for 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, but lower impact strength and mechanical shock absorption performance. It is very suitable for automatic lathe machining.
3: Nylon 4.6 (red-brown): Compared to ordinary nylon, the characteristic of Nylon 4.6 is strong 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, wear resistance, and allows for a higher maximum operating temperature.
5: Nylon 66+MOS2 (gray-black): This nylon is added with molybdenum disulfide. Compared to Nylon 66, it has improved rigidity, hardness, and dimensional stability, but reduced impact strength. The formation of molybdenum disulfide crystals enhances the crystalline structure, improving the material's bearing and wear resistance.
II: Cast nylon sheet also known as MC nylon: Monomer casting nylon in English, referred to as monomer casting nylon in Chinese. It is extremely versatile with the slogan "Replacing steel with plastic, performance is outstanding". It has various unique properties such as light weight, high strength, self-lubrication, wear resistance, corrosion resistance, and insulation. It is a widely used engineering plastic that is almost ubiquitous in all industrial fields.
Main characteristics of nylon sheets
