    摘要: An earplug (12), includes a body (14), of soft elastomeric material such as a soft resilient foam for insertion in the ear canal, and a stiffener (16), of more rigid material than the body (14). The stiffener (16), is in the form of a tube rather than a solid rod, so while the stiffener is resistant to column-like collapse, it is easily radially compressed to facilitate compression of the body as it enters the ear canal. The stiffener tube can be filled with soft resilient foam material, to block the passage of sound through the tube. The tubular stiffener can have a slot extending parallel to the length of the stiffener, to allow soft foam material to flow into the tube to fill it, as the foam material that surrounds the tube is molded. Such molding can be accomplished by extruding foam material while the tubular stiffener passes with the extruded foam through the extrusion head.

    摘要: Three-dimensional foam mouldings made of a biodegradable thermoplastic polymer, in particular starch, and preferably a second biodegradable component can be manufactured in a discontinuous process by heating the polymer, in the form of an expandable bead or sheet or the like, in a mould having any desired shape under pressure in the presence of a blowing agent and subsequently depressurising. The second component can be used to enhance the water-resistance or the mould product and can be applied after, or preferably during or before the moulding step.

Pressure drop rate and shear rate are important features in some embodiments, and the invention provides systems for controlling these parameters in an injection molding system. Another aspect involves an injection molding system including a nucleator that is upstream of a pressurized mold. Another aspect involves an extrusion system with the reciprocating screw for forming a single phase solution of non-nucleated blowing agent and polymeric material. Another aspect involves very thin walled microcellular material and very thin walled polymeric material. Another aspect provides a method for producing high weight reductions in very thin-walled parts with surfaces that have no noticeable differences from non-foamed parts.

    摘要: In an object, in particular a plate, which contains compressed granules of hard polyurethane foam and binders, the granules have a particle size not greater than 10 mm. The bulk material from which the object is manufactured contains 10 % to 90 % of polyurethane foam particles and is compressed in a first compression stage at a pressure not greater than 20 kp/cm2 and in a second compression stage at a pressure not greater than 40 kp/cm2 and a temperature less than 170°C. A plate having a thickness of approximately 8 to 11 mm manufactured by this process has a flexural strength of at least 22 N/mm2, a thickness swelling of less than 2 % and a moisture content of less than 3 %.
