With the push towards higher production rates and tighter SPC/SQC in the PVC industry today, the disadvantages of having many microingredients in a formulation become readily apparent, especially to the plant personnel who have to deal with the weighting and blending of these microingredients. The concept of adding microingredients in a “one pack” form has been explored in the past using lubricant/stabilizer combinations designed to eliminate some of the problems inherent in adding a liquid stabilizer. This paper explores the concept of a one pack system consisting of impact modifier, process aid, calcium stearate, and stabilizer. Advantages of such a one pack combination are discussed in relation to formulation, blending, materials handling, and processing.
