Application of GF Reinforced PA66 for High-speed Railway

图片
Glass fiber is a common engineering material, and glass fiber reinforced nylon 66 for high-speed iron is modified nylon fiber. When the modified nylon 66 is added with glass fiber, its flexural strength, tensile strength, and notched impact strength are greatly improved. PA66 Compound , or PA66 for short, is one of the most important engineering plastics in the world. It has the characteristics of high mechanical strength, high rigidity, high melting point, small specific gravity, anti-friction, oil resistance, and heat resistance. Widely used in transportation, medical equipment, electronics industry, daily necessities, sporting goods, and other fields. However, since it contains a large number of acid amine groups, it has strong water absorption, resulting in dimensional instability and poor performance, and also needs to be improved in terms of friction resistance, heat resistance and stability. With the continuous development of China's economy and the increasing population,...

The Best Choice for Insulation Strip Profiles - Extrusion Grade Modified PA6

With the increasing use of modified PA66. Insulated aluminum alloy profiles. According to the different processing methods, it can be divided into two types: strip type and cast type. The strip type is a combination of the formed glass fiber reinforced PA66 insulation strip and the inner and outer layers of aluminum alloy by rolling. Due to the high strength of the  GF Reinforced Nylon PA66  insulation strip, the linear expansion coefficient is close to that of the aluminum alloy, more than 90% of the heat-insulating aluminum alloy profiles in the world are produced by rolling. The base resin of the PA66 insulation strip is  Nylon PA66 Granules , or polyamide 66, which is one of the important varieties of engineering plastics. It has high mechanical strength and excellent wear resistance, self-lubricating and heat resistance, excellent low-temperature performance, self-extinguishing, acid and alkali resistance, and most inorganic salt aqueous solutions, oil and organic...

PP Modified Material  plastic has good comprehensive performance, high mechanical strength, good stiffness, excellent toughness, excellent mechanical shock absorption and wears resistance, and it shines in many industries. Modified PA66 reinforced flame retardant materials are mainly used in the fields of automobile, machinery industry, electronic appliances, precision instruments and so on. From the end-user point of view, the modified PA66 reinforced flame retardant nylon consumed by the automotive industry took the first place, and electronic appliances accounted for the second place. Automobile industry: In the automotive industry, due to the excellent heat resistance, chemical resistance, strength and ease of processing of the modified  Flame Retardant Nylon PA66 Granules , it has been used in a large number of applications and can now be used in almost all parts of automobiles, such as Engine parts, electrical parts and body parts. Engine components include intake...

History of Nylon that You Don't Know

Before the 20th century, people used natural fibers such as wool, cotton, silk and so on. But natural fabrics are not easy to obtain, and people decided to make a material that could replace natural fibers. The DuPont Group saw the potential of the market and decided to conduct research on new materials, which opened the curtain for the debut of nylon. In 1928, DuPont, founded by the DuPont family, hired and lectured at Harvard University and studied Wallace Hume Carothers as the director of organic chemistry research at the laboratory. During this period, Carothers carefully studied the polycondensation reaction (polymerization between functional groups). In 1930, the assistant of Carothers discovered that the high polyester obtained by the polycondensation reaction of the diol and the dicarboxylic acid can melt the filaments like cotton candy, and even the fibrous filaments After cooling, the stretching can be continued, and the stretching length can be several times longer. After...
