How does the processing differ for making closed and open cell foam? Describe 3 specific applications for open and closed cell foams?
What will be an ideal response?
An open cell process is done rapidly causing the material to actually "burst" and create large "pockets" of air within the material. For a closed cell, the beads would not fully expand to bursting, but the air is still enclosed within the bead. Three examples of open cell foam include: sponges, nerf footballs, and some door mats. Three examples of closed cell foam include: shoe soles, styrofoam cups, and insulation for drinking mugs.
