Abstract
A high flow polyvinyl halide compound is disclosed. The compound employs conventional ingredients plus a combination of phosphite stabilizer and hydrotalcite stabilizer which improve the melt flow index of the compound by at least 20%, as compared with a compound without the two types of stabilizers. The dramatically improved melt flow allows a molding cycle time reduction by as much as 22% because of a five-fold reduction in the fill step.
