Cast polyamide is a partially crystalline thermoplastic which is produced by means of anionic polymerization of the raw material Caprolactam. In a pressureless casting process the liquid monomer is polymerized via a controlled chemical reaction directly to a semi-finished product. As already described, cast polyamides show a number of advantageous qualities when compared to those of extrusion manufacture.
Polyamides produced by means of this process
- Have low internal stress
- Display a high degree of crystallinity
- Can be machined to almost any form
- Can be manufactured as semi-finished product or custom cast part
- Can be manufactured in almost unlimited weights and dimensions
Monomer-Cast Nylon (also called MC Nylon) has higher degrees of crystallization, are highly resistant to corrosion, organic solvents and erosion. These are extremely light (1/7 of metals) and highly economical for super-large-scale or minimal-scale production.
