A unique closed cell, cross-linked polymer foam that combines high stiffness and strength to weight ratios with superior toughness. It is non-friable, contains no CFCs, has negligible water absorption, and provides an excellent resistance to chemicals. A fine cell structure offers an excellent bonding surface that is compatible with most resins and manufacturing processes. It is ideally suited as a core material for a wide variety of light-weight sandwich structures subjected to both static and dynamic loads in service.

- high strength and stiffness to weight ratios
- good impact strength (highest elongation in class)
- low resin absorption
- high fatigue resistance
- good fire performance (self-extinguishing)
- sound and thermal insulation
- non biodegradable
- good styrene resistance
