The present invention relates to a modified polyvinyl butyral material, comprising a polyvinyl butyral composite material, a filler, an anti-hydrolysis agent, a first plasticizer, zinc stearate, calcium stearate, and a polymeric dispersant; wherein the polyvinyl butyral composite material is obtained by plasticizing a composition comprising polyvinyl butyral and a second plasticizer. The present invention also relates to a preparation method of the modified polyvinyl butyral material, a modified polyvinyl butyral product comprising at least one modified polyvinyl butyral layer prepared from a material comprising the modified polyvinyl butyral material, and the preparation method of the modified polyvinyl butyral product.

An insulation product includes a first layer of a fibrous insulating material, a second layer of a facing material attached to a first surface of the first layer, and a third layer of a slip sheet material and/or a lubricant attached to a second surface of the first layer. The first surface and the second surface are on opposite sides of the first layer and are parallel to one another. For certain applications, the insulation product may include a layer of a slip sheet material and/or lubricant attached to the first surface of the first layer instead of the second layer of a facing material.

The disclosure provides ethylene/α-olefin copolymer based co-extruded, multi-layer films, including barrier films and non-barrier films, and articles of manufacture that include the films, such as flexible bags and containers for flowable materials. The films and articles that include the films have improved flex-crak reisstance and toughness. The films and articles that include the films have good barrier properties as the barrier films include a core layer of ethylene-vinyl alcohol (EVOH) copolymer having a high ethylene content. The low amount of EVOH copolymer in the total film that is needed to achieve the flex-crack resistance, toughness, and good barrier properties, further allow for the recycling of the films and articles of manufacture.

Provided are a sliding elastic body capable of imparting excellent sliding properties and resistance to protein adsorption and, at the same time, maintaining sealing properties; and a syringe gasket, a catheter, and a tire which include the sliding elastic body. The present invention relates to a sliding elastic body including an elastic body whose surface is fully or partially laminated with a fluororesin film, the laminated elastic body being treated with a fluorinated oil.

A packaging material for batteries including a laminate in which at least a base material layer, a metal layer, and a sealant layer are laminated in order. The battery packaging material satisfies the relationships of: (A1−A2)≥60 N/15 mm; and (B1−B2)≥50 N/15 mm. A1 is a stress in elongation by 10% in the MD direction and B1 is a stress in elongation by 10% in the TD direction in the laminate, and A2 is a stress in elongation by 10% in the MD direction and B2 is a stress in elongation by 10% in the TD direction in the base material layer.

A polyvinyl chloride composition for powder molding includes a polyvinyl chloride (A) an amount of 100 parts by mass, a plasticizer in an amount of 110 parts by mass or more and 150 parts by mass or less, and an acrylic polymer in an amount of 4 parts by mass or more and 23 parts by mass or less. The polyvinyl chloride (A) has an average particle diameter of 50 μm or more and 500 μm or less and an average degree of polymerization of 1,350 or more. The acrylic polymer has an average particle diameter of 0.01 μm or more and 10 μm or less and contains a constitutional unit derived from a (meth) acrylic ester in an amount of 50 mass % or more.

An absorbent article having improved softness signals is disclosed. The article may include a topsheet or a backsheet including a nonwoven web. The web may have a basis weight of 30 gsm or less, may be formed of spunlaid fibers including polyolefin and up to 5 percent by weight TiO.sub.2, and may be impressed with a pattern of bond impressions to a bond area percentage of at least 10 percent forming a pattern of bonded regions and raised regions. The web may have opacity of 42 or greater; have an average height difference between bonded regions and raised regions of at least 280 μm; be hydroengorged; and/or have a cross-machine direction tensile strength of 350 gf/cm. A nonwoven web manufactured to have a suitable combination of such features exhibits an enhanced appearance of softness, soft tactile feel and satisfactory mechanical attributes, while being relatively cost effective.

A lining element includes at least three layers and is configured to be mounted to a structure exposed to wear. The lining element has a wear-impeding polymer layer, an energy-absorbing polymer layer and a reinforcing polymer layer. The reinforcing layer is located adjacent the structure exposed to wear, whereas the energy-absorbing layer is located between the reinforcing layer and the wear-impeding layer. The wear-impeding layer is located on top of the energy-absorbing layer.

A multilayer film includes an inner layer system having a first surface and a second surface; a first skin layer bound to the inner layer system at the first surface of the inner layer system; and a second skin layer bound to the inner layer system at the second surface of the inner layer system. The inner layer system contains ≥50.0 wt % of a first ethylene-based polymer being a high-density polyethylene having a density of ≥940 and ≤970 kg/m.sup.3; and one or both of the first or the second skin layer(s) is a sealing layer including a second ethylene-based polymer being a linear low-density polyethylene comprising polymeric moieties derived from ethylene and from 1-hexene or 1-octene, having a density of ≥890 and ≤915 kg/m.sup.3. The multilayer film is a bi-directionally oriented film, wherein the orientation in both directions is introduced in the solid state.

A frictional power transmission belt is provided, containing an adhesion rubber layer in contact with at least a portion of a tension member extending in a longitudinal direction of the belt, in which the adhesion rubber layer is formed of a first vulcanized rubber composition containing a rubber component and a filler, the filler contains substantially no silica and contains 30 parts by mass or more of carbon black based on 100 parts by mass of the rubber component, and the tension member has, on a surface thereof, an overcoat layer formed of a second vulcanized rubber composition containing a rubber component and silica.
