This invention relates to a nonwoven material consisting of one or more layers of nonwoven webs of essentially continuous cellulosic filaments, characterized in that within each layer each of the three bonding mechanisms: a) hydrogen bonding, b) filament intermingling and c) merged filament bonding occur for bonding the essentially continuous cellulosic filaments. Further it relates to a process for the manufacture and to various uses of this material.

A breathable multilayer spun bonded polypropylene membrane having a coated pressure sensitive adhesive capable of allowing air and moisture vapor to pass through it. The adhesive is formed of a copolymer comprising a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with a surfactant and emulsified to produce bubbles which form pores when the copolymer is set with about 80% to about 90% of the pore sizes ranging from about 200 microns to about 300 microns and a pore density in the cured pressure sensitive adhesive ranging from about 4200 per inch.sup.2 to about 4600 per inch.sup.2, said pores being uniformly distributed to form a flow path through the adhesive.

An engineered wood product with at least one engineered-wood substrate or core layer (such as, but not limited to, OSB), with a connectivity layer configured to reflect RF signals (e.g., wifi and/or cellular signals), thereby enhancing connectivity in adjacent or proximate spaces or areas. The connectivity layer may be a metallic material, such as, but not limited to, aluminum or copper. The layer may be a sheet or film or foil of the metallic material applied to the surface(s), or integrated into the interior, of the substrate or core layer. The layer also may be a coating or deposited layer. A connectivity layer may be “sandwiched” between two or more engineered-wood substrates, thereby forming a composite panel or product. The surface of the connectivity layer may be embossed or patterned.

A laminate, containing two or more polyolefin resin layers, wherein at least one polyolefin resin layer (A) contains a cellulose fiber including a cellulose fiber having a fiber length of 0.3 mm or more dispersed in the layer; a content of the cellulose fiber in the polyolefin resin layer (A) is 1% by mass or more and less than 60% by mass; and wherein a polyolefin resin layer (B) different from the polyolefin resin layer (A) is laminated in contact with the polyolefin resin layer (A).

External thermal insulation composite systems described herein include a concrete or masonry wall and a thermal insulation board on the concrete or masonry wall. The thermal insulation board includes a polyurethane/polyisocyanurate foam having a density of less than 70 kg/m.sup.3 according to ASTM D 1622. Methods of preparing the external thermal insulation composite systems and the thermal insulation boards are also described.

A glass-resin composite of the present invention includes at least a plurality of glass sheets and a resin sheet which are integrally combined with each other via an organic resin intermediate layer, wherein, out of inner glass sheets of the plurality of glass sheets, at least one glass sheet has a crystallinity of 30% or less and a Young's modulus of 75 GPa or more.

An illustrative embodiment of a manufactured surface component may be comprised of a textile material on a first face and an elastomer material on a second face, wherein said elastomer material is bonded to said textile material, wherein said manufactured surface component is substantially planarly configured, wherein an area of said first face and said second face is from about 0.04 square inches to about 4.0 square inches, wherein a thickness of said manufactured surface component is from about 0.3 mm to about 2.5 mm, and wherein said manufactured surface component is substantially free of any petrochemical-derived plastics, petrochemicals, and toxins.

A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least 0.5 as tested by ASTM C423-17 and a flame spread index of less than 25 and a smoke development index of less than 150 as tested by ASTM E84 dated 2009.

A panel is configured for attachment to a mounting surface of a building structure. The panel includes a first end surface and a second end surface, spaced from each other along a longitudinal axis; a top edge surface and a bottom edge surface, spaced from each other and offset from the longitudinal axis; and an inner surface and an outer surface, opposed to each other and extending from the first end surface and the second end surface. The inner surface includes a contact portion and a contour portion. The contact portion is disposed on a reference plane. The contour portion is contoured toward the outer surface, away from the reference plane, such that the contour portion defines a channel. The channel extends along at least a portion of a length of the panel, between the first end surface and the second end surface.

Provided is a glass laminate article including a core substrate having a first surface, a second surface opposite to the first surface, and a side surface between the first surface and the second surface; a first metal sheet on the first surface; a second metal sheet on the second surface; a glass substrate on the second metal sheet; and an adhesive member bonding the glass substrate to the second metal sheet, wherein the core substrate has lower thermal conductivity than a medium density fiberboard (MDF).
