Neat and reinforced semi-aromatic polyamides examples of properties

Liquid PA or cast nylon is a block copolymer of caprolactam and a prepolymer that can be processed in the liquid state, which simplifies tooling and processing machines. 

Cast nylon is used for prototypes and small production runs processed by casting, roto-moulding and reaction injection moulding (RIM), possibly with structural reinforcements (SRIM) such as glass mat or fabric. 

The properties are close to those of PA 6 but there is only one producer and a few grades, such as self-lubricating or FDA compliant.
