Foam and sandwich core materials are generally used as core structural materials for composite laminates, delivering added strength, stiffness, and insulation, without adding weight. Our vinyl foam sheets are easy to handle, readily conform to shapes, and can be bonded in layers to add thickness. Whereas our polyisocyanurate mix and pour foams are perfect for filling cavities, flotation, and sculpting and are available in 2lb and 6lb densities. Finally, our sandwich core materials are ideal for building lightweight structural layers with even greater strength-to-weight ratios.

Foam and Sandwich Core can be found in infrastructure applications, wind energy, land transport, and throughout the marine industry.

At, look for foam in one of several categories:

  • Mix-and-pour polyurethane foam--Once mixed equally, this foam expands rapidly to fill any sized cavity; best suited for flotation, sculpting, and for structural support.
  • Vinyl foam--All selections are quality DIAB Divinycell brand; sold by the sheet and used chiefly as sandwich core material.
  • Divinymat--Engineered to be both a sandwich core and a flow media for resin infusion; Divinycell foam sheet scored and held together with light scrim backing.
  • Polyisocyanurate foam--Most frequently used for mold-less pattern making; sold by the sheet and in a 4' x 6' block.
