Product Description
Extruded nylon is the most important engineering plastics. The product is widely used in almost every fields and it’s the most widely used plastic of the five engineering plastics. There are many types of nylon, including nylon 6, nylon 66, nylon 11, nylon 12, nylon 46, nylon 610, etc. However, nylon 6 and nylon 66 are the most important varieties and the output of nylon 6 and nylon 66 are dominant.
PA66 is a translucent or opaque milky white to yellowish crystalline polymer made of condensation of hexanediamine and adipic acid. Compared with PA6, its mechanical strength, stiffness, heat resistance and wear resistance, creep resistance are better, but the impact strength and mechanical shock absorption are decreased. The products’ color of PA66 is cream.
