Commonly used modified nylon performance application

Modified nylon is one of the five major engineering plastics, which has the characteristics of many varieties, large output and wide application. However, due to the wide variety of modified nylon, some products have similarities in the application field, and some products are very different and need to be carefully distinguished.

The repeating amide group is a modified nylon in the molecular backbone. -[NHCO]-a general term for thermoplastics.

PA6 and PA66 are the main types of modified nylon and dominate; followed by PA11, PA12, PA610, and PA612 in addition to PA1010. PA46, PA7, PA9, PA13. New varieties of nylon 6I, nylon 9T, nylon MXD6 (barrier resin), etc.

Modified nylon is a kind of toughness angle translucent or milky white crystalline resin, as the nylon content of rubber products is generally 15000-30000. Nylon has high impact toughness, high softening point, high heat resistance, low friction resistance, abrasion resistance, self-lubrication, shock absorption and noise reduction, oil resistance, weak acid resistance, alkali resistance and general solvent resistance; good electrical insulation, self-extinguishing, odorless, aging resistance, etc.

Modified nylon and glass fiber have excellent affinity, so it is easy to change. But nylon dyeing poor, not easy to color. Nylon has high water absorption, which affects dimensional stability and electrical properties. Fiber reinforcement can reduce the water absorption of the resin and make it work under high temperature and high humidity.

Modified nylon has milky white or yellowish transparent to opaque cutin-like crystalline polymer; It can be freely colored, has good toughness, abrasion resistance, good self-lubrication, small rigidity, low temperature resistance, bacteria resistance, slow combustion, slow extinguishing from fire, dripping and foaming.

What is the market demand and development of nylon?

The high-strength changes in the nylon market will become larger and larger, and new reinforcement materials such as inorganic whisker reinforcement will become larger and larger. Carbon fiber reinforced PA is mainly used for vehicle engine parts, mechanical parts and aviation equipment parts.

The difference between modified nylon material and pure nylon

There are two common materials on the market: modified nylon materials and pure nylon. What is the difference between these two materials? Compared with pure nylon, modified nylon material has greater impact toughness, stiffness, temperature resistance, creep and fatigue. The modified nylon material has mechanical elongation, molding shrinkage, water absorption and abrasion resistance.

Generation Principle of Modified Nylon

The polymerization reaction of modified nylon is carried out below the polymer dissolution point. The late stage of polymerization is characterized by a rapid increase in content, and at the same time, with the polymer knot and condensation. People usually react directly.

Performance advantages of modified nylon

Nylon is a kind of engineering plastics with excellent mechanical properties, outstanding corrosion resistance, oil resistance, heat resistance, high modulus and so on. Reinforced, flame retardant modification, can significantly improve its heat resistance, modulus dimensional stability and flame retardancy, modified nylon is widely used as a substitute for metal, wood and other traditional materials, used in automotive, electrical and electronic, power tools and other industries.

Nylon Modified Material Market Application

Nylon raw material as the base material, by adding chemical or physical additives, through physical mixing or chemical reaction will change the physical and chemical properties of nylon itself, the formation of plastic granular products. The addition of a compatibilizer to the reinforced nylon G-5 cause the glass fiber to react with the nylon to produce a chemical bond that improves strength and toughness. Toughened nylon can be added with a toughening agent G-1. Abrasion resistant nylon, halogen free flame retardant nylon, conductive nylon, flame retardant nylon and so on.
