Expandable Film Adhesive is a heat-activated foaming structural material used to create foam core composites. When placed in a heated tool, it foams to fill the mold cavity, forming parts of any shape without the need for time-consuming machining processes or costly press equipment.

Create 3D parts that are both lightweight and strong through a simple, clean process. Just shape your tool, add a 1/16” thin sheet of Dribond Expandable Film Adhesive, and heat to 250ºF to 300ºF. The cavity will fill to match the 3D shape of the tool. Compared to traditional manufacturing and machining methods, Expandable Film Adhesive enables faster cycle times, reduces waste material, and optimizes production processes by eliminating secondary machining and assembly operations.
