Nylon plastic because it has good comprehensive performance, including mechanical properties, heat resistance, abrasion resistance, chemical resistance and self-lubrication, and low friction coefficient, have certain flame retardant, easy to machining, is widely used in automobiles, electrical equipment, the mechanical structure, transportation equipment, textile, paper making machinery and other fields.
Nylon is reinforced with glass fiber and other fillers to improve performance and expand application.
In some areas, nylon, as a structural material, has made high demands on its strength, heat resistance and cold tolerance, and its modification is more targeted.
Modification of nylon plastics.
01 improve the water absorption of nylon and improve the dimensional stability of the products.
Improve the flame retardancy of nylon to meet the requirements of electronics, electrical and communication industries.
Improve the mechanical strength of nylon to achieve the strength of metal material instead of metal.

Improve the low temperature resistance of nylon and enhance its ability to withstand environmental strain.
Improve the wear resistance of nylon to meet the high requirement of wear resistance.
Improve the antistatic property of nylon to meet the requirements of mine and its mechanical application.

Improve the heat resistance of nylon to adapt to high temperature conditions such as automobile engine.

Reduce the cost of nylon and improve product competitiveness.

The development of modified nylon plastics.

Glass fiber reinforced PA research in the 1950 s, but the formation of industrialization is in the 1970 s, since 1976, the United States dupont toughening PA66, development of surplus countries to big companies to develop new modified PA products, the United States, Western Europe, Japan, the Netherlands, Italy, vigorously develop enhanced PA, flame retardant PA, PA, filling a large number of modified PA on the market.
Compatilizer technology developed in the 1980 s, to promote the development of PA alloy and countries around the world have developed a PA/PE, PA/PP, PA/ABS, PA, PA/PC/PBT, PA/PET, PPO/PA, PA, PPS, PA/I.C P (LCP), PA/PA thousands of alloy, widely used in automobile, motorcycle, electronics, electrical machinery, textile, sports supplies, office supplies, household appliances and other industries.
Modified nylon varieties growing in the 1990 s, the period of modified nylon towards commercialization, and formed a new industry, and the rapid development of the late 1990 s, the world nylon alloy production of 1.1 million tons/year.
In terms of product development, the main direction is high-performance nylon PPO/PA6, PPS/PA66, toughening nylon, nano nylon and halogen-free flame-retardant nylon.
In applications, significant progress has been made in auto parts, electrical components development, such as car modified nylon intake manifold with high flow has been commercialized, the complex components of plastic, besides is of great significance in terms of application, more important is to extend the service life of components, to promote the development of engineering plastics processing technology.
It is of great significance for the further light weight of the automobile to be applied to the micro-foaming injection molding.

Development trend of modified nylon plastics.

As engineering plastics nylon plastic has a strong vitality, mainly lies in its modified to realize high-performance, followed by cars, electronics, communications, electronics, machinery and other industries to the requirements of the product's performance is more and more intense, the rapid development of related industries, promoting the progress of high-performance engineering plastics, modified nylon plastic future development trends are as follows.
01 the market demand of high strength and high rigidity nylon is more and more big, the new reinforced material, such as inorganic whisker reinforced, carbon fiber reinforced PA will become the important varieties, mainly used in automobile engine parts, mechanical parts and aviation equipment parts.
02 nylon alloying will become the mainstream of the development of modified engineering plastics.
Nylon alloying is an important way to achieve high performance of nylon, and is also the main means to make nylon special materials and improve the properties of nylon.
By mixing other high polymers, it can improve the water absorption of nylon, improve the dimensional stability of products, and low temperature brittleness, heat resistance and wear resistance.
The manufacturing technology and application of nano nylon will be developed rapidly.
The advantages of nano-nylon lie in its thermal properties, mechanical properties, flame retardancy and barrier properties.
The flame retardant nylon used in electronics, electrical and electrical appliances is increasing day by day, and the green flame retardant nylon is getting more and more attention from the market.
Antistatic, conductive nylon and magnetic nylon will become the preferred materials for electronic equipment, mining machinery and textile machinery.
