A method comprising: a) determining the bow () in the extension direction of one or more linear paths on an outer surface or outer surfaces () of an extruded ceramic part () so that maximum extrusion direction bow () of the one of more linear paths or outer surfaces () may be determined of the extruded ceramic greenware part (); b) identifying the linear path on the outer surface or the outer surfaces () having maximum convex bow; c) placing the greenware part () on a carrier with the linear path on the outer surface or the outer surface location having the maximum convex shape in contact with the carrier; and d) processing the greenware part () while disposed on the carrier with the linear path on the outer surface or the surface having the convex shape on the carrier, such that the bow () is reduced as a result of the process.

Process for preparing ceramic bodies

A building structure includes a framework of: (a) metal studs having walls that define an interior channel; (b) a cellular backing material extending lengthwise within the interior channel of at least a portion of the metal studs; (c) a thermally insulating layer extending over multiple metal studs; (d) fasteners extending through the thermally insulating layer, through a wall of a metal stud and into the cellular backing material within the interior channel of the metal stud; and (e) a cladding attached to the framework of metal studs by means of the fasteners.

Prepare an article by providing an extruded thermoplastic polymer foam having a cavity defined therein and placing a vacuum insulation panel entirely within the cavity.

Thermal insulating panel composite

The invention a method of forming complex shape of styrenic polymer foams in which a pressing surface is created, for example, by planing/machining a layer of an as formed extruded styrenic polymer plank, contacting said plank with a contoured die face and pressing the foam to form the complex shape.

Cushions for dynamic impact applications include anisotropic cellular polymers made in an extrusion, expanded bead or reactive foaming process. The anisotropic behavior represented by C/C, C/Cand C/C, wherein C, Cand Crepresent the compressive strength of the cellular polymer in each of three orthogonal directions E, V and H, respectively, as measured by compressing a 25-50 mm thick sample of the cellular polymer at a strain rate of 0.08 sto 25% strain, Crepresents the sum of C, Cand C, and at least one of C/C, C/Cand C/Chas a value of at least 0.40, up to about 0.80. The cellular polymer also preferably has density of 1.75 to 2.35 pounds/cubic foot and a compressive stress in the direction of maximum compressive strength of 290-600 kPa at 25% strain when used for headliner countermeasure applications. The cushions are useful in automotive applications such as automotive headliners, door panels, knee bolsters, pillars, headrests, seat backs, load floors or instrument panels.
