Nylon engineering plastics are widely used in electronic and electrical, car, construction, office equipment, machinery, aerospace and other work because of its high functional advantages in mechanical function, durability, corrosion resistance, heat resistance and so on. Under the instigation of "replacing steel with plastics" and "replacing wood with plastics", nylon engineering plastics are widely used in various fields due to its functional characteristics and advantages.

Functional characteristics of nylon engineering plastics

Mechanical function: the tensile strength, flexural strength, impact strength, hardness, rigidity, modulus and toughness of nylon engineering plastics are all good. Especially, the strength, modulus, hardness, rigidity and wear resistance of nylon engineering plastics are further improved through fiber reinforced composite materials or alloys mixed with other polymers. Nylon engineering plastics have good resistance to abrasion, self lubrication and fatigue resistance, which is one of the important reasons for their wide application.

Heat resistance: nylon engineering plastics have a high melting point, generally above 240 ℃. The heat resistance of aromatic nylon is higher than that of aliphatic nylon. If certain reinforcing fillers are added, their thermal stability function will be greatly improved, and the thermal deformation temperature can be 250 ℃.

Processing function: nylon engineering plastics are thermoplastics. After melting, they have low viscosity under the effect of shear force, good fluidity, easy to form and process, and easy to maintain.

Electrical function: under dry conditions, nylon has good electrical insulation, which can be used as insulation data, especially good high-frequency insulation data. However, nylon is easy to absorb water and moisture, and its insulation will decline in the future.

Solvent resistance: nylon engineering plastics have good chemical stability, alkali resistance and weak acid resistance; It belongs to solvent resistant plastics, especially resistant to aromatic hydrocarbons and common organic solvents, and can be used in chemical and chemical instruments; In the environment where some metals are easy to rust, such as water meters, nylon data can be used instead.

Flame retardancy: nylon has good flame retardancy and is generally not easy to burn; The antibacterial agent can also make it have antibacterial and self purification functions.

Advantages of nylon engineering plastics

Compared with metal, nylon engineering plastics also have the characteristics of light weight, low operation noise, no spark, no rust and no electromagnetic interference during operation. In addition, when used as a gear, it can buffer collision and impact through its own deformation and deflection, and can reduce part of the load caused by device deviation.

Nylon also has the advantages of sufficient materials, many varieties, low price, easy recycling, outstanding dyeing and high precision of the products.
