FluidSolids® is an innovative biologically degradable composite material. It has been developed with the aim of meeting a wide range of requirements in both physical and design terms. In its visual appearance and haptic properties, FluidSolids® resembles a timber material. When it comes to forming options, on the other hand, the material is related to petrochemical plastics. Its first practical applications – the FS bowls, the FS stool and dividing partition elements for Architonic Concept Space – served as a model illustration of the specific properties and design potential of this hybrid material. FluidSolids® proves once again how inseparably design and material are linked, showing that design can go well beyond the mere shaping of a form.
