  • Publication number: 20150057398
    Abstract: Improved solventless processing technology for additive blends containing a polymer carrier, including those which have high level of additives, is described. High concentrations of low-melting, sticky additives lead to phase separation and extrusion instability, such that pellets cannot be formed from such additive blends by traditional extrusion process. These blends include those with a high level of active additives that have been described in the literature as Type A Superblends. Here a polymer typically acts as the carrier of the additives. The new and improved technology involves the solid state compaction processing, using a tubular die, of such impossible-to-pelletize additive blends of the Type A composition to produce commercially useful pelletized additive blends.
