| 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® 8073 is used in combination with the catalyst Addonyl® Kat NL and the activator Addonyl® 8120 during the production of Cast Nylon (PA-6 G). This allows users to combine various properties, and to tailor materials specifically to requirements. Addonyl® 8073 is a solid high-molecular-weight polyol. Addonyl® 8073 is used in rotomolding to prevent the formation of voids and pinholes. It also improves the impact value and the machinability of the obtained cast nylon. Addonyl® 8073 has the following advantages: - Colorless, wax-like flakes
- The product is easily soluble in molten caprolactam without residue
Use: The reactivity of the polymerizing melt is influenced by various factors. Lanxess advises against a concentration of > 2% p.b.w., because problems with the polymerization may occur.Information provided by Lanxess. |
