Abstract: A weather seal includes an elongated micro-cellular foam bulb, and an elongated micro-cellular foam fin element attached to an extending along the length of the foam bulb. The fin elements includes a spine having opposed planar surfaces and at least one microcellular foam barb extending outwardly and at a downward angle from each surface and along the length of the spine. As an alternative to barbs, another option is to use a higher durometer foamed thermoplastic elastomer in a hollow circle shape that would push into a retention pocket. A t-slot version that has a foamed bulb and a polypropylene base is another option.

Abstract: In a handrail including a carcass, a stretch inhibitor within the carcass, and a sliding layer bonded to the carcass, at least a portion of the carcass has a gas phase dispersed in a solid polymer matrix. The gas phase can reduce a density of the carcass by at least 5% or 10%, or about 15%, as compared to a density of the polymer matrix. The carcass can have a generally uniform distribution of gas bubbles in the polymer matrix, which can define a generally closed cell structure in the polymer matrix. The gas phase can be formed of particles of a syntactic foam dispersed in the polymer matrix. The handrail can further include a cover. The carcass and the cover can be formed of thermoplastic materials, and the cover can represent between 10 and 30% of the overall TPU required for the handrail.

Abstract: The present invention provides a continuous process for solid-state expansion of a biopolymer, e.g., polylactic acid, which can be used to manufacture reduced-density thermoplastic materials with improved physical and thermal properties. By incorporating multiple stages of heating into the process as a means to regulate heat flux, unprecedented control of microstructure and crystallinity can be achieved. Thermoplastic sheets with the distinct cellular characteristics imparted by the process disclosed herein were found to be thicker and stronger than materials prepared by conventional processes. Thermoforming sheets with such characteristics enabled the production of light-weight, thermally-stable, compostable products that resist warping, and are thus suitable for a range of industrial applications.

Abstract: Films may be used as interleaves between hard and non-compressible surfaces such as surfaces of sheets or plates made of glass, metal, such as steel, polycarbonate, and/or poly(methyl methacrylate). The films may be embossed and/or may include a foamed core layer having a plurality of micro-voids. In particular, the films may include a polyolefin, a basis weight of between about 30 gsm and about 70 gsm, an embossed thickness of between about 150 microns and 800 microns, and a stiffness of between about 150 grams and about 750 grams according to the Circular Bend Stiffness Test.

Abstract: A method includes providing a production line configured for continuous fabrication of polymer or predominantly polymer roofing boards by setting and expansion of precursor materials on a conveyor. A first polymer or predominantly polymer material foam precursor is dispensed to the production line, and allowed to rise and at least partially set to form a foam core layer for an insulation board, the foam core layer for the insulation board having a first density. A second polymer or predominantly polymer material foam precursor is dispensed to the production line and allowed to rise and set to form a core layer for a cover board, the foam core layer for the cover board having a second density greater than the first density. The combined thickness of the foam core layer for the insulation board and the core layer for the cover board is set by constraining the expansion of the combined foam precursors using a downstream forming conveyor disposed above the rising foam precursors.
