MC Nylon, means Monomer casting nylon is a kind of comprehensive used engineering plastic ,can be applied almost every industrial field. The caprolactum monomer first be melted,and added catalyst,then poured it inside molds at atmosphere pressure so as to shape in different profiles ,such as rod ,plate or tube.The molecule weight of MC nylon can reach 70,000-100,000/mol,three times than that of nylon 6/6/.Eminence mechanical properties comparing with other materials.MC nylon plays a more and more important role in the material list recommended to the more fields.
