FOAM Masterbatches

Reductions of plastic part weight by up to 20% for density critical applications such as fuel floats and energy saving transportation equipmen.

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.
