  • Patent number: 6231961
    Abstract: A layered structure that includes a product mixture of numerous particles, a foamable substance, such as including a liquid binder, and a reacted dry binder is provided. The particles preferably are comprised of cellulosic, fibrous materials. The dry binder reacts with the liquid binder to create a strong bond among separated particles. The particles are separated during transport, together with the dry binder, before the dry binder is reacted with the foamed liquid binder. Upon contact with the liquid binder, the dry binder reacts to cause desired adhesion among the separated particles. The reacted dry binder is disposed relatively inwardly of the product mixture, while the liquid binder is located outwardly thereof, with at least some of the liquid binder, after curing, being disposed on outer portions of the product mixture. The layered structure also includes one or more outer members or panels that are laminated or otherwise joined to the outer surface portions of the product mixture.

  • Patent number: 6231960
    Abstract: Biodegradable and/or compostable polymers are made from isoprene, 2,3-dimethyl-1,3-butadiene or like conjugated dienes and a crosslinking agent having a cleavable linking group such as ethylene glycol dimethacrylate. These polymers can be used to make absorbent foams that are useful in absorbent articles such as diapers, as well as other biodegradable articles such as films, and latexes useful as binders and adhesives.

  • Patent number: 6207244
    Abstract: A wall or structural element, preferably for the body or parts of the body of motor vehicles, is formed for dissipating impact forces and introducing them into the load-bearing parts of the body of the motor vehicle. The wall or structural element is a composite element formed of a thin-section wall part and a molding which is bonded to the latter over its full surface area. The molding being composed of reinforcing elements fixed in a foamed binder. The reinforcing elements are derived from renewable raw materials in cut or uncut form, preferably monocotyledons or dicotyledons. Two or more composite elements, in each case having wall parts and moldings, may be bonded to one another to form a joint component, for example a motor vehicle door.

  • Patent number: 6171985
    Abstract: A low trauma pressure-sensitive adhesive coated substrate comprising a sheet material, tape or laminate structure designed to adhere to skin or like surfaces. The pressure-sensitive adhesive layer of this adhesive coated substrate is a fibrous adhesive layer generally having a basis weight of from 5 to 200 g/m2 applied to a conformable backing or substrate. The fibrous adhesive layer has a textured outer face and persistent porosity between discrete adhesive fibers. Generally, the fibrous adhesive layer has a MVTR (measured by ASTM E 96-80 at 40° C.) of at least 1000 g/m2/day, preferably at least 6000 g/m2/day.
