Description
PA 12 (also known as Nylon 12) is a good general-use plastic with broad additive applications and is known for its toughness, tensile strength, impact strength and ability to flex without fracture. PA 12 has long been used by injection molders due to these mechanical properties.
Uses
Nylon 12 is a long-chain polyamide with a relatively long methylene chain and low amide group density. It possesses excellent properties such as low density, low melting point, good thermal stability, high decomposition temperature, low-temperature resistance, oil resistance, corrosion resistance, and resistance to friction loss. It is widely used in automotive system piping, chemical and petroleum pipelines, and hydraulic transmission systems. Nylon 12 has low moisture absorption, making it suitable for precision electrical parts and instruments. It also has good gas barrier properties and is non-toxic, making it suitable for food and pharmaceutical packaging. Furthermore, it exhibits excellent resistance to termite damage, making it suitable for wire and cable sheathing. In short, Nylon 12, with its superior properties, is widely used in defense, electronics, communications, machinery, food, and other industries, and its application prospects are very broad.
Synthesis
Nylon 12 (polyamide 12) is a significant component of tubings used in automotive brake and fuel lines. Nylon 12 has generally been produced from cyclododecatriene by converting the cyclododecatriene to laurolactam, which is a starting monomer for the industrial production of nylon 12. Cyclododecatriene may be made from butadiene as the raw material. One method for the production of butadiene that may be considered non-environmentally friendly is the production of butadiene derived from petroleum products.
