Cast Nylon 6, a plastic of high molecular weight, 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® Kat NL is used as an catalyst during the production of Cast Nylon (PA-6 G). In combination with the activator Addonyl® 8120 and further products from the Addonyl series users can combine various properties and tailor materials specifically to requirements. Addonyl® Kat NL in combination with Addonyl® activators enables short production intervals (demolding time under 10 minutes depending on the work piece is possible) at simultaneously low processing temperatures. 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. |
