Recently, the University of Stuttgart in Germany has developed a new non-toxic, fully flexible fiberboard (flexible HDF) that can be used to produce furniture or interior decoration, using rapidly regenerative raw materials. Fiberboard is widely used in the furniture industry or interior decoration, depending on the manufacturing process and density, usually to add containing formaldehyde or isocyanate resin, both of which have serious health risks to the human body.
Ordinary fiberboard is small in flexibility and is limited in the decoration design. In addition, although it can be recycled, it cannot be composted.
The new flexible fiberboard, developed by Professor Hana Dach, Director of the Institute of Structural Design and Design at the University of Stuttgart, uses 80-90 per cent of the new flexible fiberboards from renewable raw materials, such as straw, or wheat, corn, oats, barley or rye straw fibers. This natural fiber is found all over the country as the remnants of the plant and is very low cost.
Another advantage of the new flexible fiberboard is that it has a silicate content of up to 20% of the weight of dry fibers. Since silicates are natural flame retardant materials, the addition of pure mineral additives meets the German standard for flame retardant in the material category. The adhesive used is an environmentally compatible thermoplastic elastomer. As a result, the fiberboards produced are virtually free of formaldehyde and isocyanate, minimizing health risks throughout the product life cycle.
By adding different adhesives, the flexibility and stability of the plate can be changed for different applications. Through a variety of coatings, it can also be laminated and waterproof, coloring can be achieved by tinted lamination. At the end of your useful life, fiberboards can be recycled and even composted. This results in the dual effect of saving materials and environmental protection.
Registered under the name “Bioflexi”, this eco-friendly material is inexpensive, and this novel high density and flexible fiberboard can be used to produce furniture and partitions of all shapes, as well as floors with anti-slip and impact resistance. HDF flexible plates have been patented in the United States, Europe and Malaysia. The University of Stuttgart commissioned a technical licensing agency to industrialize the invention and is looking for partners to bring it to market.
