Foam 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.
