Addonyl® 8108

Addonyl® 8108 a plastic of high molecular weight, is produced through an anionic polymerization of caprolactam. During the pressure less 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® 8108 - Processing Information - 1

Application Information
  • Addonyl® 8108 is used as an activator during the production of Cast Nylon (PA-6 G). In combination with the catalyst Addonyl® Kat NL 
  • Use
    • The reactivity of the polymerizing melt is influenced by various factors. Recommended 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. Addonyl® 8108 is easily soluble in molten caprolactam. The caprolactam melt containing the activator is susceptible to oxidation. Thus, we recommend working under inert gas.

Safety & Health

Safety Precautions

A receiving inspection is recommended. In moist conditions, with the formation of carbondioxide, Addonyl® 8108 converts to a solid, high-melting and insoluble polyurea.
