摘要：
The present invention provides a flexible high-density fiberboard which is essentially free of formaldehyde and isocyanates and comprises 70 to 90% by weight of straw fibers, and 30 to 10% by weight of a thermoplastic elastomer and one or more optional additive(s). Furthermore, the present invention provides a method for manufacturing such a flexible high-density fiberboard comprising the steps of providing straw fibers, providing a thermoplastic elastomer in powder form, optionally providing one or more additive(s), dry mixing the straw fibers, the thermoplastic elastomer powder and optionally the one or more additive(s), such that a mixture comprising 70 to 90% by weight of the straw fibers, and 30 to 10% by weight of the thermoplastic elastomer and one or more of the optional additive(s) is obtained, extruding the obtained mixture at a temperature such that the thermoplastic elastomer powder is in a molten state, and pressing the extruded mixture.
