  • SPREADABLE GRANULES, USE OF SAME AND GRASS LAWN OR ARTIFICIAL GRASS LAWN WITH SUCH SPREADABLE GRANULES AS INFILL GRANULES
    Publication number: 20240092978
    Abstract: Spreadable granules as infill granules for grass and artificial turf fields are proposed, which granules have a polymer matrix with a percentage between 10% by mass and 100% by mass of at least one biodegradable polymer and at least one filler from the group of natural fillers, embedded in the polymer matrix with the at least one biodegradable polymer. The invention provides for the spreadable granules to have at least one filler from the group including comminuted fruit kernels. In addition, the invention relates to the use of such spreadable granules as infill granules for grass and artificial turf fields, as a spacer material for the storage of construction materials, such as, e.g., floor covering materials, and as grit for road maintenance in winter.

  • Plastic material made from a polymer blend
    Patent number: 6509397
    Abstract: A plastic material made from a polymer blend, is characterized in that said material contains at least one lignin-based natural polymer, in particular based on alkali lignin produced during the extraction of cellulose, and at least one other synthetic and/or natural polymer which increases the impact resistance, proteins excluded. The inventive plastic material has excellent characteristics. It is biodegradable due to the natural polymer content and has, to a considerable extent, an ecologically neutral CO2 balance. The polymer blend can be used advantageously in place of wood or wood materials.

  • Method for producing a rod-shaped composite part and rod-shaped composite part
    Patent number: 6478494
    Abstract: A method for producing a substantially rod-shaped composite body (6) consists of a core (4) enveloped by at least one polymer, according to which the plasticized polymer (5) is extruded onto the core (4). At least one natural polymer is used and a sliding agent on the basis of native oils and/or waxes is added before or during extrusion. The method is used for the production of writing, drawing, cosmetic pencils.
