To prepare samples with an active ingredient, a linear low-density poly(ethylene) masterbatch “AMPE 143101” 2 ZANDER ET AL. It is possible that increased efficacy was not seen with increased loadings due to an activity threshold for ZPT (potentially limited by environmental copper avail- ability) in which no significant trend truly exists upon increasing the active content in the sample beyond 1000– 1500 ppm.[18,24] Furthermore, it appears from Figure 2 that the ZPT-containing samples may have shown slightly enhanced activity toward S. aureus. B) Photograph comparing samples containing equivalent loadings of ZPT; natural color plaque (left) and a plaque containing blue tint masterbatch (right) ZANDER ET AL. 7 (99.99%) in S. aureus at ZPT loadings of 1000–1500 ppm (Figure 2).

COLORMATRIX™ OXYGEN SCAVENGER PRODUCT FAMILY Amosorb™ and Amosorb™ SolO2 active oxygen scavengers ColorMatrix™ Amosorb™ additives are oxygen scavenging polyester concentrates that create an active barrier against the ingress of oxygen through the walls of PET containers.

Ideally, depending on the polymer and screw length, the melt temperature should be lower than the activation temperature of the CFA to avoid gas losses through the material hopper. The activation of Hydrocerol Chemical Foaming Agents should happen approximately in the middle of the barrel exceeding the temperature indicated in the technical data sheet of the processed Hydrocerol concentrates grade. PHASE 1: MIXING AND ACTIVATING The CFA is mixed into the melt for maximum distribution and then activated in the barrel, to release the gases.

Bob has been by my side during our transformation and is unquestionably the right leader to take PolyOne to even greater heights in the future.
