Polycore™ is a rigid polyisocyanurate foam that has flame and smoke properties that are better than the common urethane foam. Polycore™ has some flexibility and therefore has a high shear value at all densities and holds up very well in high vibrating or oscillating environments. Polycore™ is often used as a core material in pultrusion processes and can also be used as a shock absorber in nuclear waste containers. Polycore™ is available in a wide range of densities and custom cut sizes.
