Cast nylons are a range of polyamides produced by a casting process involving the anionic polymerisation of caprolactam.
The family of nylons consists of several different types. Nylon 6/6, nylon 6, nylon 6/10, nylon 6/12, nylon 11, nylon 12, and nylon 6-6/6 copolymer are the most common.
Cast nylons are used in a wide range of applications, from a simple equipment support pad, to a sophisticated drum in a machine that sorts thousands of coins a minute, to a sheave on a crane that can lift 1,000 tons, to a component used to eviscerate chickens! There is perhaps no other process that can produce parts weighing from one pound to over eight hundred pounds in tooling that, relatively speaking, costs peanuts.
China’s demand for nylon 6 driving it, caprolactam pricing in Asia moved upward dramatically during Q1 and the attractive pricing is pulling in material from the world.
Asia nylon 6 and 6,6 markets inched upward in March. The spot nylon 6 price for Chinese and Taiwanese brands stabilized, while US$ imported nylon 6 price were strong.
