Described herein are physically crosslinked, closed cell continuous multilayer foam structures that includes a foam layer comprising polypropylene, polyethylene, or a combination of polypropylene and polyethylene and a polyamide cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer and at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

An article comprising a polymeric foam, wherein the polymeric foam contains a continuous polymer matrix defining cells therein, the polymer matrix containing: (a) from 25 to 65 weight percent of one or more olefin block copolymer having a melt index of two grams per ten minutes or more, (b) from 65 to 25 weight percent of one or more chlorinated olefin polymer having a Mooney viscosity less than 60 (ML 1+4, 125° C.), and (c) from 5 to 30 weight parts of antimony trioxide relative to 100 weight parts of polymers in the polymeric foam, with weight percent values relative to total polymer weight in the polymeric foam; a process for preparing the article.

A traction mat wherein the foam is reinforced with a layer of fabric or fiber between the CLCC foam layer and the substrate or underlying surface. The layering is preferably a first foam layer and a fabric layer impregnated with a pressure sensitive adhesive. This prevents the CLCC foam from being bonded directly to the substrate and allows the fabric/fiber to support the CLCC foam such that the entire assembly can be removed in one piece without the CLCC foam disintegrating. The introduction of the reinforcing fabric and/or fiber layer eliminates any residual CLCC foam from being bonded to the substrate. Consequently, the traction mat can be easily lifted away and removed.

Arrangements described herein relate to systems, apparatuses, and methods for a disposable kit containing medical items configured for a medical device including a head cradle to support a head of a subject, the disposable kit includes a container that encloses a head cradle pad configured to be affixed to the head cradle, at least one fiducial marker configured to be disposed on a location at the head of the subject, and at least one enclosure configured to cover a portion of the medical device.

A film for a metal layer laminate board and a metal layer laminate board have excellent stiffness, while capable of suppressing fluctuation of a dielectric constant before and after pressing. The film for a metal layer laminate board includes a porous resin layer having a tensile elastic modulus at 25° C. of 800 MPa or more and 2000 MPa or less.

A porous resin film for a metal layer laminate board and a metal layer laminate board are provided to suppress damage to a metal layer disposed on an inner peripheral surface of a through hole and to have excellent electrical connection reliability even under the high temperature environment. The porous resin film for a metal layer laminate board is used in lamination of a metal layer. The porous resin film for a metal layer laminate board has a minimum thermal expansion coefficient X in a plane direction perpendicular to a thickness direction and a thermal expansion coefficient Z in the thickness direction. In the porous resin film for a metal layer laminate board, a ratio (Z/X) of the thermal expansion coefficient Z in the thickness direction to the minimum thermal expansion coefficient X is 3.5 or less.

A porous polyimide film is provided to suppress an increase in a dielectric loss tangent even when immersed in water. In the porous polyimide film, a difference between a dielectric loss tangent T1 after being left to stand for 24 hours under an atmosphere of 25° C. and relative humidity of 50% and a dielectric loss tangent T2 after immersion in water for 24 hours under an atmosphere of 25° C. is 0.0030 or less.
