Generic name for a family of polyamide polymers characterized by the presence of the amide group –CONH. By far the most important are nylon 66 (75% of U.S. consumption) and nylon 6 (25% of U.S. consumption). Except for slight difference in melting points, the properties of the two forms are almost identical, though their chemical derivations are quite different. Other types are nylons 4, 9, 11, and 12 (see Grade).Профиль безопасности
Questionable carcinogen withexperimental tumorigenic data by implant. Reacts violentlywith F2. When heated to decomposition it emits toxicfumes of NOxСвойства и приложения
Polyamides thermoplastics are prepared by condensation by reacting a carboxylic acid (i.e., RCOOH) and an amine (i.e., R'NH2 ) giving off water. Hence, the basic monomer unit in polyamides is [—NH—(CH2 )2 —CO—]n. These resins are well known under the common trade name Nylon®. Owing to the wide diversity of different additives or copolymer as starting materials, there are several commercial grades of nylon resins available. each of them with particular properties. The main grades are nylon®6 and nylon®66, these being the two grades having the highest strength. Industrially, nylon 6 is obtained in a batch process by mixing caprolactam, water and ethanoic acid in a reaction vessel heated under inert nitrogen atmosphere at 230°C, while nylon 66 is prepared from adiponitrile, itself obtained from butadiene or propylene, which is converted into hexamethylene diamine (HMD). HMD is then reacted with adipic acid to yield nylon by a condensation reaction.POLYAMIDE 6 HPLC 0.005-0.020MM (5-20UM)& запасные части и сырье
