Cast Nylon is produced through an anionic polymerization of caprolactam. During the pressureless casting process the monomeric caprolactam melt is poured into the mold and directly polymerized by a specific chemical reaction and then forms a semi-finished product or molding. Addonyl® P is used as an activator during the production of Cast Nylon (PA-12 G or PA-6 12 G). In combination with the catalyst Addonyl® Kat NL users can produce materials with constant high quality. Addonyl® P is an activator on the basis of aromatic carbodiimides and is used for PA-12 G or PA-6 12 G. By using Addonyl® P a longer pouring time can be achieved. Use: The reactivity of the polymerizing melt is influenced by various factors. Lanxess recommends an activator concentration of at least 0.5% by weight. The quantity of the activator to be used, however, decisively depends on the size and form of the casting mold. Information provided by Lanxess. |
