Not Your Father’s Purging Agent
There are two important messages for today’s processors with regard to purging. First, as we near the peak of the “rapid improvement” stage of purging technology, the products now available are not the same old purging compounds of the past. Second, the “low-hanging fruit” has been picked—future technical improvements will likely be incremental and future improvements in productivity will require a shift in focus, toward transition planning and process optimization.
