Foaming Agent masterbatches provide several benefits to injection molded plastic articles:
•    Reductions of plastic part weight by up to 20 % for density critical applications such as fuel floats and energy saving  transportation equipment.
•    Elimination of sink marks on injection molded parts - sink marks are shallow depressions on a part surface and are the result excessive shrinkage in thicker areas of the part - they can be minimized by adding a small amount of foaming agent which creates just enough internal pressure within the molded part to offset excessive shrinkage and reduce sink marks.
