PA has good comprehensive properties, including mechanical properties, heat resistance, abrasion resistance, chemical resistance and self-lubrication, and has low friction coefficient, certain flame retardancy, easy processing, suitable for glass fiber and Other fillers are filled to enhance modification, improve performance and expand the scope of application.
There are many varieties of PA, including PA6, PA66, PAll, PA12, PA46, PA610, PA612, PA1010, etc., as well as many new varieties of semi-aromatic nylon PA6T and special nylon developed in recent years. Nylon-6 plastic products can use sodium metal, sodium hydroxide, etc. as the main catalyst, and N-acetyl caprolactam as the co-catalyst, so that δ-caprolactam can be produced directly in the model through anion ring-opening polymerization, which is called cast nylon. This method facilitates the manufacture of large plastic parts.
