Product Description
MC nylon also known as monomer casting nylon, is a product obtained by direct polymerization of caprolactam monomer by a mold under the action of strong base and some cocatalysts. The molecule weight of MC nylon can reach 70,000 to 100,000 per mol. And its comprehensive performance is excellent. The natural color of MC nylon is ivory. Besides natural MC nylon, we can also produce green oily nylon, grey-black molybdenum disulfide nylon, graphite nylon, glass fiber nylon, blue nylon, etc.
