Main uses and development trend of nylon

Brief description: main uses and development trend of nylon

polyamide fiber is commonly known as nylon, with English name of polyamide (PA for short), density of 1.15g/cm. It is the general name of thermoplastic resin containing repeated amide group [nhco] on the molecular main chain. Therefore, when the blade of the mixer hits it at this time, it includes aliphatic PA, aliphatic aromatic PA and aromatic PA. Aliphatic PA has many varieties, large output and wide application. Its name depends on the specific number of carbon atoms of the synthetic monomer. It was invented by the famous American chemist Carloses and his research team

nylon is a term for polyamide fiber (nylon), which can be made into long fiber or short fiber

modified nylon is a kind of engineering plastics. It is a granular product formed by changing its physical properties with nylon raw material as the base material. The output of such products is modified according to the different needs of some manufacturers

modified nylon generally includes: reinforced nylon, toughened nylon, wear-resistant nylon, halogen-free flame retardant nylon, conductive nylon, flame retardant nylon, etc

1. Thermal properties: glass transfer temperature (TG) and melting point (TM); High thermal deformation temperature (HDT); High temperature for long-term use (ul-746b); Large temperature range; The coefficient of thermal expansion is small

2. Mechanical properties: high strength, high mechanical modulus, low latency, strong wear and fatigue resistance

3. Others: good chemical resistance, electrical resistance, fire resistance, weather resistance and dimensional stability. The output of such products is modified according to the different needs of some manufacturers. The modified nylon roughly includes: reinforced nylon, toughened nylon, wear-resistant nylon. When feeding, pay close attention to the main motor flow meter and all kinds of indicators to change the state halogen-free flame-retardant nylon, conductive nylon, flame-retardant nylon, etc. Providing services such as innovation and entrepreneurship, utilization and promotion, information consultation, financing, intellectual property protection, talent introduction and training for new material enterprises in the initial stage, modified nylon has many characteristics. Therefore, it is widely used in automobiles, electrical equipment, mechanical departments, transportation equipment, textiles, paper machinery, etc

use of modified nylon

nylon rod has the characteristics of good toughness, strong wear resistance, oil resistance, earthquake resistance, good tensile and bending strength, small water absorption and good dimensional stability, so it is used to process various wear-resistant high-strength parts

development trend of modified nylon

nylon, as the largest and most important variety of engineering plastics, has strong vitality, mainly because it realizes high-performance after modification, followed by the automotive, electrical, communications, electronics, machinery and other industries, which have increasingly strong requirements for high-performance products. The rapid development of related industries has promoted the process of high-performance engineering plastics. The future development trend of modified nylon is as follows

① the market demand for high strength and high rigidity nylon is increasing, and new reinforcement materials such as inorganic whisker reinforcement and carbon fiber reinforced Pa will become important varieties, mainly used for automotive engine parts, mechanical parts and aviation equipment parts

② nylon alloying will become the mainstream of the development of modified engineering plastics. Nylon alloying is an important way to realize the high performance of nylon, and it is also the main means to manufacture nylon special materials and improve the properties of nylon. By mixing with other polymers, the water absorption of nylon is improved, the dimensional stability of products is improved, and the low-temperature brittleness, heat resistance and wear resistance are improved. Thus, it can be used for different vehicle types

③ the manufacturing technology and application of nano nylon will develop rapidly. The advantage of nano nylon is that its thermal properties, mechanical properties, flame retardancy and barrier properties are higher than those of pure nylon, and the manufacturing cost is equivalent to that of ordinary nylon. Therefore, it has great competitiveness

④ the number of flame-retardant nylon used in electronic, electrical and electrical appliances is increasing day by day, and the green flame-retardant nylon has been paid more and more attention by the market

⑤ antistatic, conductive nylon and magnetic nylon will become the preferred materials for electronic equipment, mining machinery and textile machinery

⑥ the research and application of processing aids will promote the process of functionalization and high performance of modified nylon

⑦ the application of comprehensive technology and the refinement of products are the driving forces to promote its industrial development
