MC nylon English name: Monomer casting nylon, Chinese name: monomer cast nylon, engineering plastics are widely used, almost all industrial areas throughout. It is the use of anionic polymerization technique, melting increases with catalyst under atmospheric pressure caprolactam casting molds in various shapes formed in the reaction of casting products. The molecular weight of MC nylon 7-10 million for the general nylon 6, nylon 66, 3 times, so its mechanical properties are much better than other nylon material, is the State Planning Commission to promote the importance of energy saving materials. Over the years the company continued to insist on the MC nylon modified technology research and development, greatly widened its applications. The MC nylon substrate in the reaction process of adding various modifiers, such as composite oil lubricants, molybdenum disulfide, graphite, glass fiber, carbon fiber, nano slag and so on, to make it more wear and corrosion resistance, aging, self-lubricating, absorbing vibration, noise absorption; the same time, simple structure, process and tooling, manufacturing costs are relatively low, as alternative to copper, stainless steel, aluminum, an ideal material such as PTFE.
