Karen Fung multi-seal tie factory (www.hengfengduo.com) located at No. 1-16, Longgang District, Shenzhen, Guangdong, contact Recreation Road, about six Henggang: Wang cast nylon Ronne's the difference between an ordinary a polymerization method in different ways as nylon 6 has a molten lactam monomer in the presence of acidic catalysts for ring-opening polymerization of the water requires high pressure and long reaction, the polymerization apparatus more complex, multi-step. MC nylon is molten caprolactam monomer in the presence of inductive medium anionic ring-opening polymerization, at atmospheric pressure and a temperature of 170 degrees, just a few minutes to complete the reaction. (2) the difference between the common nylon polymer molecular weight polymer product properties is generally 30,000 or less, and a crystallinity of not more than 40%; cast nylon and about 7-10 million molecular weight, degree of crystallinity of more than about 50%, compared with density large. Thus, in terms of convenience strength, stiffness, wear resistance and chemical resistance, cast nylon 6 is much superior than ordinary nylon, and water absorption is relatively small, dimensional stability than ordinary nylon 6 is good.
