See also General information under Nylon 6

General Description : A semi-crystalline, yellowish engineering thermoplastic that is often coloured brick red. It has higher crystallinity and better chemical resistance than nylon 6 or 6,6 and similar water absorption, though the associated dimensional change is less. Compared to other (aliphatic) nylons it has much better retention of properties at elevated temperatures, reportedly because of the "highly symmetrical" polymer chain and its relatively high concentration of amide groups (four methylene groups in both the acid and the amine segments).

Applications are broadly similar to other nylons - engineering, electrical and electronic components particularly those exposed to (sustained) high temperatures.
