MC Nylon (Natural/white)
MC Nylon,means Monomer Casting Nylon, is a kind of engineering plastics used in comprehensive industries, has been applied almost every industrial field.
The caprolactam monomer is first melted, and added catalyst, then poured it inside moulds at atmosphere pressure so as to shape in different castings, such as: rod, plate, tube. The molecule weight of MC Nylon can reach 70,000-100,000/mol, three times than PA6/PA66. Its mechanical properties are much higher than other nylon materials, such as: PA6/PA66. MC Nylon plays a more and more important role in the material list recommended by our country.
Since the end of 1980’s, Guangzhou Engineering Plastics Industireis Company has devoting herself on developing the technology of MC Nylon modification, greatly extended the applications in different industries. Basing on the MC Nylon, reinforced with variety of additives during the reaction, such as lubricant, molybdenum disulfide, graphite glass fiber, carbon fiber etc, to improve the properties, higher performance of wear-resistance, corrosion-resistance,
self-lubrication, vibration-absorption, noise-absorption. At the same time, as the technics and structure of the moulds is quite simple, so that it can be manufactured in lower cost, becomes the ideal substitutes of bronze, stainless steel, Babbitt alloy , PTFE and so on.
