As a kind of engineering plastic with excellent comprehensive performance, PA66 has been widely used in high-speed railway components, but high-iron requires high strength and high toughness of materials, and pure PA66 is difficult to meet these conditions. Under this background, modification of PA66 develop rapidly. Large foreign engineering plastics companies continue to introduce modified nylon for high-speed rail. For example, Rhodia has launched the innovative TECHNYLSTAR AFX series PA66 technology. It combines superior fluidity and maximum reinforcement with unique rigidity, temperature resistance and unparalleled processability, which greatly expands the range of PA66 applications.
