Cell structure of Baynat based foam

Baynat® is a raw material for semi-rigid foam used in fiber reinforced composites for lightweight construction. Baynat® based foam is a very light-weight material available in densities between 15 and 40 kg/m³. The typical compression strength at 40% deflection in rise direction is in the range from 75-150 kPa (0,75 – 1,5 bar).

Baynat® based foam is thermally insulating like expanded polystyrene (l = 34-37 mW/m*K) but unlike other light-weight insulants it is both highly effective in noise absorption and resistant to rather high temperatures.

One application is the use as a core for the manufacture of sandwich headliners in the automotive industry. In that case, Baynat® is optimized for indoor emission and smell. The facings are composed of fiber-reinforced polyurea and decorative layers.

This system not only allows rapid prototyping but can also serve as self-supporting acoustic panel:

Baynat can be used as a core for lamination
