Elastic attachment hot melt adhesive composition and a disposable absorbent article made with the same
The invention features a hot melt adhesive composition based on olefin polymers that can be used for elastic attachment in the manufacture of a disposable article. The hot melt adhesive includes from about 3 to about 10% by weight of a first propylene-based copolymer having a melt index measured by ASTM D1238 (190 C., 2.16 kg) of no greater than about 5, a second propylene-based polymer with a viscosity at 190 C. of no greater than about 5000 cps, a first tackifying agent having a softening point of at least about 90 C. and from about 5% by weight to about 20% by weight of a plasticizer.
Transparent member for automobile interior parts
The present invention relates to a transparent member for an automotive interior part. In one embodiment, the transparent member for the automotive interior part includes: a light source; an optical pattern layer formed over the light source; and a first light-transmitting skin layer formed on the optical pattern layer and including about 1 part by weight to about 25 parts of a first inorganic filler dispersed in 100 parts by weight of a first transparent resin matrix, wherein the first inorganic filler includes spherical calcium carbonate (CaCO.sub.3).
POLYURETHANE ADHESIVE WITH CHEMICAL RESISTANT
There is provided a pressure sensitive adhesive composition comprising a polyurethane polymer that comprises the reaction product of a polyisocyanate component and a polyol component. The polyol component has a hydrophilic-lipophilic balance (HLB) less than 10. The polyurethane further comprises 0.5 to 10 wt.-% of hydrophilic polymerized units having an HLB greater than 12, such as a reaction product of a polyethylene glycol polymer. In another embodiment, the polyurethane further comprises pendent ethylenically unsaturated groups. Also described are articles such as laminating tapes and protective films as well as methods of bonding substrates with the pressure sensitive adhesive and laminating tape.
SOUNDPROOF STRUCTURE, SOUND ABSORBING PANEL, AND SOUND ADJUSTING PANEL
There are provided a soundproof structure, which can have high soundproofing performance in a wide frequency band and in which visual recognition of through-hole can be suppressed, and a sound absorbing panel and a sound adjusting panel using the soundproof structure. A sheet member having a plurality of through-holes passing therethrough in a thickness direction and a sound absorbing body disposed in contact with one main surface of the sheet member are provided. An average opening diameter of the through-holes is 0.1 m or more and less than 100 m. Assuming that the average opening diameter of the through-holes is (m) and an average opening ratio is a parameter A expressed by A=+.sup.2 is 92 or less.
BIODEGRADABLE PACKAGING FOR SHIPPING
A biodegradable, thermally insulated mailer and cooler, and method of making them, are disclosed. The thermally insulated packaging material are made from laminated starch foam and bio-plastic film. The lamination can be performed by heat bonding, without the use of an adhesive bonding agent, to produce biodegradable packaging materials that can pass ASTM and other certifications for home compostability and marine environment safety.
ELECTRET-TREATED SHEET AND FILTER
An object of the present invention is to provide a low pressure-loss type of filter which has a high dust collecting capability and suppresses the lowering of the dust collecting capability even after cleaning. The present invention relates to an electret-treated sheet including at least a surface layer, a high dielectric layer and a back-surface layer, while having the high dielectric layer between the surface layer and the back-surface layer, wherein the surface layer and the back-surface layer are each a thermoplastic resin film having a relative dielectric constant of smaller than 6 at 100 kHz; the high dielectric layer is a material having a relative dielectric constant of 6 or larger at 100 kHz; and the surface layer and the back-surface layer each have a static charge due to electrostatically charge; and to a filter using the same.
Adhesive articles permitting damage free removal
The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.
SENSOR, INPUT DEVICE, AND ELECTRONIC APPARATUS
An electronic apparatus includes: an exterior body; a pressure-sensitive sensor having a first surface and a second surface; a support body supporting the pressure-sensitive sensor such that the exterior body faces the first surface; and a first deformation layer disposed at least either between the first surface and the exterior body or between the second surface and the support body. The pressure-sensitive sensor includes a capacitive sensor electrode unit including a sensing unit, a reference electrode layer, and a second deformation layer disposed between the reference electrode layer and the sensor electrode unit. The first deformation layer and the second deformation layer satisfy a predetermined relationship.
TEXTURED CLEANSING ARTICLE
The present invention relates to dual textured treatment cleansing articles comprising first and second outer members forming first and second sides of the article. The first and second sides are both textured, although preferably the sides have different textures to provide the user with differing degrees of cleaning in a single cleansing article. For example, in one embodiment, the first side has coefficient of friction greater than 0.50, such as from 0.50 to about 0.75 and more preferably from about 0.55 to about 0.65, and the second side has coefficient of friction less than 0.50, such as from about 0.30 to 0.50 and more preferably from about 0.35 to about 0.45
PROTECTIVE PACKAGING PRODUCT AND METHOD OF MANUFACTURING A PROTECTIVE PACKAGING PRODUCT
A protective packaging product comprises a plurality of stacked layers, at least some layers preferably comprising a foamed material, and at least some layers being adhered to an adjacent layer. The inventions proposes that at least some layers are made of a polysaccharide material, and that adjacent polysaccharide layers are adhered to each other by means of a polysaccharide bonding material.
