摘要： A moisture-curable adhesive composition comprises a polymer component selected from a silane-terminated polyalkylene oxide and/or a polyurethane; a plurality of amino-silane modified wollastonite fibers having an average aspect ratio of from about 1.5:1 to about 12:1 and an average fiber length of from about 6 μm to about 825 μm; at least two fillers, wherein one of said fillers is untreated and a second of said fillers is treated with a modifier selected from the group consisting of a fatty acid derivative, a silane, a titanate, and mixtures thereof wherein at least one of said fillers is irregularly shaped; and a rheology modifier. The composition preferably further comprises a plurality of irregularly-shaped crumb rubber particles having an average particle size of between about 0.5 to 1.5 mm. The composition is useful for adhering tiles to surfaces, especially large format tiles to substantially vertically-extending wall surfaces.

摘要： A semicrystalline copolyester resin composition formed by twin screw extrusion of various ingredients includes copolyester resins, antiblock, slip and antifog additives. This semicrystalline copolyester resin can be extruded on to PET film or coextruded with PET resin to form clear PET films with antifog properties. These films with antifog properties are produced in a single step without the use of solvent and does not involve any secondary step for coating a separate antifog layer. This minimizes the cost and time required by a converter to make such clear antifog films. These films containing the heat seal copolyester resin can be heat sealed to clear APET trays. Contents within the trays, such as food, can be seen without fogging on the inside of the film that is used to seal the tray. The seals are strong and the peels are smooth giving a very good packaging performance.

摘要： A polymer composition for use in a hot melt adhesive comprises at least one semierystalline, low molecular weight (LMW) propylene-based polymer; at least one essentially amorphous, high molecular weight (HMW) propylene-based polymer; and at least one essentially amorphous, LMW propylene-based polymer. A hot melt adhesive composition further contains a tackifier, a plasticizer, an antioxidant, and optionally a wax, a filler, a colorant, a UV absorber, another polymer, or combinations thereof The hot melt adhesive is useful for a variety of industrial applications where bonding of low surface energy substrates is encountered, including disposable nonwoven hygienic articles, labeling and other assembly applications. Particularly preferred applications include nonwoven disposable diaper and feminine sanitary napkin construction, diaper and adult incontinent brief elastic attachment, diaper and napkin core stabilization, diaper backsheet lamination, industrial filter material conversion, and surgical gown and surgical drape assemblies. The composition demonstrates improved peel strength while maintaining very good creep resistance.

摘要： A method and system of using a polyolefin-based, hot melt adhesive improves creep performance of elastic strands adhered to another substrate. Some deflection, greater than 1°, of the exit angle formed by a line normal to the axis of a neutrally-positioned applicator and the elastic strand extending from the applicator is introduced. Preferably, deflection of the entrance angle is also introduced and a head tilt angle is also provided. The use of deflection improves creep performance or allows for a reduced amount of adhesive to be used to achieve the same or similar creep performance. The elastic strands may be used to form a leg cuff in personal care products, such as diapers, and the substrate to which they are applied could be a polyethylene film or non-woven materials.

摘要： A low activation temperature heat seal hot melt adhesive for packaging applications based on a blend of metallocene catalyzed polyolefin polymer, tackifying resin, wax and other optional additives. In order to achieve the high viscosity suitable for an extrusion heat seal application, the adhesive composition of the invention is highly loaded with polymer, and thus should have a viscosity of about 50,000 centipoise or more measured at a temperature of 300° F. Accordingly, the hot melt adhesive composition contains about 50% to about 90% by weight of metallocene catalyzed polyolefin polymer, about 5% to about 50% by weight of tackifying resin, about 0.5% to about 40% by weight of wax, about 0.1% to about 5% by weight of a stabilizer or antioxidant, and 0% to about 25% by weight of optional additives. The hot melt adhesive composition must have an activation temperature of about 160° F. or less, and provide a minimum peel force of about 1.0 pound per inch in order to meet the sealing performance requirements for packaging food and other consumer goods.

摘要： A non-pressure sensitive hot melt adhesive for use in mailer applications uses a styrenic block copolymer (SBC) with a hydrogenated mid-block as the primary polymer in the composition. The adhesive contains about 10% to about 50% by weight of the SBC, about 2% to about 30% by weight of a polyolefin polymer as a secondary polymer in the composition, about 10% to about 70% by weight of a suitable plasticizer, about 0% to about 30% by weight of a wax, about 0% to about 50% by weight of one or more tackifying resins, about 0.1% to about 4% by weight of a stabilizer, and about 0% to about 3% by weight of auxiliary additives, so that the viscosity of the composition is equal to or less than about 10,000 cP at 163° C. The formulation balances the cohesive and adhesive strength required to insure the adhesive fails cohesively to prevent paper tear. In addition, the presence of the secondary polymer allows additional oil absorption into the polymer, thus preventing oil from staining the substrates or surfaces without significantly increasing the viscosity.

摘要： A hot melt adhesive composed of a styrene-butadiene-styrene polymer having a relatively high diblock content and styrene content, a second styrenic block copolymer having a lower diblock content than the styrene-butadiene-styrene polymer, which is preferably a styrene-isoprene-styrene polymer, together with tackifying resin, and liquid plasticizer. The preferred styrene-butadiene-styrene polymer contains a styrene content of greater than 30 percent and a diblock content greater than 30 percent by weight. When used in conjunction with a styrene-isoprene-styrene polymer, the hot melt composition provides improved peel strength at 5° C., and when used as a pad attachment positioning adhesive, did not exhibit adhesive transfer at 40° C.

摘要： A hot melt adhesive composed of an ethylene vinyl acetate copolymer, a hydrogenated styrenic block copolymer, a tackifying resin, and a liquid plasticizer. The preferred ethylene vinyl acetate copolymer has a vinyl acetate content between 8 and 28 percent by weight, and the preferred hydrogenated styrenic block copolymer is a styrene-ethylene-butylene-styrene having about 30% styrene content and essentially no diblock. The hot melt gives excellent peel strength when used as a construction adhesive for disposable nonwoven articles. It can also be formulated to exhibit very low bleed through and blocking characteristics when used on low basis weight nonwoven fabrics.
