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.

The key characteristics of modified nylon depend on the adhesion strength, content, aspect ratio and trend of the fiber and resin. Injection and extrusion molding. Modified nylon materials are widely used in aerospace, vehicles, machinery, chemical and other fields.

Modified nylon material is added to PA 30 **glass fiber, PA mechanical properties, dimensional stability, temperature resistance and aging resistance will be significantly improved, fatigue resistance is not enhanced 2.5 times. The modifying material is used to change the properties of the nylon. Modified materials include glass fiber, asbestos fiber, carbon fiber, titanium metal, etc., especially glass fiber, to improve the temperature resistance, dimensional stability, stiffness and mechanical properties of nylon, especially engineering plastics with good mechanical properties.

There are two kinds of glass fiber modified nylon materials: long fiber modified nylon and short fiber modified nylon. Glass fiber modified nylon materials are widely used in gears, bearings, fan impellers, pump blades, bicycle parts, auto industry parts, fishing gear and some precision engineering products.

Modified nylon material has good abrasion resistance, temperature resistance, oil resistance and chemical resistance. It can also reduce the water absorption and shrinkage of raw materials. The modified nylon material also has good dimensional stability and excellent impact toughness.

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.

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.
