Characteristics of Bendywood®-veneers: 
These veneers are clean because they are cut in the longitudinal grain direction. 
Tightest bending radii can be achieved using common membrane presses.
Theoretically, a 0,3 mm thick Bendywood® veneer can only be bent to a radius of approx. 3 mm, as the tightest possible bending radius of Bendywood® is approximately ten times the thickness of the material.
Pictures on the Bendywood® website show that this limit can be exceeded. 
This is astonishing because the pressing power of a membrane press is only about 0,7 kg/cm².
The reason for this is that water-based glue was used, so that the moisture content of such a thin veneer rises well over the usual 12% before pressing.
It is also unexpected that the veneers bent in the longitudinal direction do not break at the sharp 90° edges, as the splitting strength or tensile strength across the grain of the Bendywood® is not comparable to the breaking strength when bent against the grain direction.
