Ultralight materials are those which, having to boast an extreme reduction in weight, generally combine several properties with each other. For this reason alone, the materials assembled here can no longer be classified according to conventional criteria into categories such as wood, metal, plastic and textiles. They are often hybrid materials or sandwich and composite materials. The objective of ultralight materials is to offer the widest possible range of processing options, which is why designers, interior designers and trade fair stand builders are particularly interested in them.
Ultralight materials include, for example, so-called scrims, delicate yarn constructions that strengthen, reinforce or combine products, or keep their shape. Scrims are the material of choice when fabrics are too oversized and knitted fabrics are too pliable owing to their mesh structure. Other ultralight materials are various materials consisting of foams and coatings, including pure aluminum foam panels, which are highly recommendable where, for all the lightness, great stability is required and at the same time an aesthetically appealing appearance is important. Generally speaking, ultralight panels range from various sandwich constructions made of metal and coated hard foam panels to those with a balsa wood core.
Alongside the minimized weight, ultralight materials, be they rigid or flexible are often characterized by their minimal thickness, the fact that they are thermally and/or acoustically insulating, flame retardant, resistant to chemicals and recyclable.
