Bioflexi

This high-density panel is a recyclable and compostable freeform fiberboard for architectural applications.

Fiberboards are widely used in the furniture industry and for internal house finishing. This new type of high‐density fiberboard is equally suitable for the production of free‐form furniture and partitions as well as slip‐resistant and shock absorbent floor‐ covering and –underlayment respectively. No formaldehyde and isocyanate components are applied, making it the ideal solution for different indoor applications.

The fiberboard consist of 80 % to 90 % straw, a natural fibre and residual material which is available worldwide. Therefore, the raw material’s price is very cheap and is not competing with food production. The fiberboards can be made of wheat, maize, rice, oat, barley or rye straw. In case of applying rice straw, the fiberboards have an extra advantage of having a silicate concentration of up to 20 % of the dry fibre weight.

Since silicate is a natural fire‐retardant material, the material classification “particularly fire‐resistant” according to the German DIN 4102‐B1 standard can be fully met through adding minimal mineral‐based flame retardant‐additives. An eco‐friendly thermoplastic elastomer is used as a binder. Accordingly, the board can be produced with no formaldehyde and isocycanate contents, thus minimizing the health risks during the product’s entire life cycle. At the end of its service life, the fibreboard may be also recycled or composted. This indicates that waste is hereby prevented twice: once during the production by using agricultural by‐products and the second time by composting the product at the end of its life‐cycle.
