Dyplast Products^®  manufactures high-performance structural Polyisocyanurate (ISO-CF^®, an advanced polyurethane) as well as Expanded Polystyrene (Dyplast EPS) rigid foams in varied densities for use in composite applications - - particularly sandwich composites and composite insulation board! Dyplast has a demonstrated composite substrate material to meet each of the top ten priorities of composite engineers:

1. Rigidity/stiffness/strength
2. Light-weight
3. Thermal and dimensional stability
4. Thermal efficiency
5. Temperature range diversity
6. Fabrication flexibility (size, dimension, shape, tolerance)
7. High volume capacity
8. Substrate material and adhesive compatibilities
9. Excellent water/moisture resistance
10. Cost efficiency

ISO-CF and Dyplast EPS as foam cores can achieve high bending strength-to-weight ratios and resistance to deformation (axial/flexural/torsional) when combined with laminate substrates such as carbon, metal, fiber/glass, or poly(carbonate/vinyl/ethylene/etc.).

Polyisocyanurate

ISO-CF and ISO-CF/HT are quite unique since, as closed-cell thermoset rigid foam cores, they offer performance effective from at cryogenic temperatures up through 350°F (177°C) - - while offering impressive thermal insulation characteristics not available in alternative structural foam cores. Dyplast's ISO-CF densities range from 2 to 6 lb/ft³, (32–96 kg/m³) and are available with:

• high-volume,
• quick-turnaround
• sheets, blocks, or fabricated shapes typically much larger and diverse than alternatives
• precise dimensional tolerance.

Expanded Polystyrene

Dyplast EPS has closed cells, no voids, and is light-weight - - a resilient structural rigid foam providing a host of distinctive properties. No other product within this cost structure provides the strength-to-weight ratios, thermal efficiency, temperature compatibility, dimensional stability, and resistance to water, moisture, shrinkage, rot, insects, and mildew. Dyplast EPS is manufactured across densities from 1-2 lb/ft³ (16-32 kg/m³) .
