A polymer foam adhesive tape including: a substrate film; a polymer foam layer provided on one surface of the substrate film; a first adhesive layer provided on the polymer foam layer; and a second adhesive layer provided on the other surface of the substrate film, in which the polymer foam layer has a density of 0.3 g/cm.sup.3 or less, and a thickness ratio of the substrate film to the polymer foam layer is 1:3 to 1:10.

An adhesive tape for application to a component of a motor vehicle, consisting of a primer layer having a self-adhesive lower side and a self-adhesive upper side, where the primer layer is embodied such that it is activatable for chemical reaction with an adhesive. The use of an adhesive tape, to an assembly, and to a method is also provided.

Stiffening assemblies for use with labels or shelf label channels are described. The stiffening assemblies can be incorporated with one or more labels and provided so as to be conveniently used with shelf label channels or other point-of-sale displays.

A surface protection film includes an adhesion layer that includes a blend of a first hydrogenated styrene block copolymer, a second hydrogenated styrene block copolymer different from the first hydrogenated styrene block copolymer, and polyethylene. An Adhesion Build Value of the surface protection film is less than 2.5 after the adhesion layer has been attached to a textured polycarbonate substrate and heated to 90 C. for 10 minutes.

A double-sided adhesive tape is provided, which includes a pressure-sensitive adhesive layer on a first side of the adhesive tape, a thermal bonding film layer on a second side of the adhesive tape, and a carrier layer interposing the thermal bonding film layer and the pressure-sensitive adhesive layer. A total thickness of the adhesive tape is 50-500 m.

Pressure sensitive adhesive articles include a substrate, and a layer of pressure sensitive adhesive in contact with the substrate. The pressure sensitive adhesive layer includes a pressure sensitive adhesive matrix, and at least one active enzyme dispersed within the pressure sensitive adhesive matrix. The active enzyme remains active for extended periods of time.

Pressure-sensitive adhesive formulations based on acrylic or rubber adhesives are provided in combination with an aluminum phosphorous salt intumescent flame retardant and a nitrogen containing flame retardant which can act as a blowing agent through thermal decomposition. These flame retardant additives can be incorporated into the adhesive in levels of 10 to 30 percent by weight. These formulations are then placed on a polymeric flame retardant substrate in either a single-sided or double-sided form.

A pressure sensitive adhesive composition and a protective film employing the same are provided. The pressure sensitive adhesive composition includes 30-45 parts by weight of a tackifier and 55-70 parts by weight of a polymer. The polymer includes at least one block copolymer. The block copolymer includes a vinyl aromatic block polymerized by a vinyl aromatic monomer and a conjugated diene block polymerized by a conjugated diene monomer. The block copolymer meets one of the following conditions: (1) the content of the vinyl aromatic monomer is from 15 wt % to 25 wt % and the content of the vinyl group of the conjugated diene block is less than or equal to 45 wt % or, (2) the content of the vinyl aromatic monomer is from 10 wt % to 15 wt % and the content of the vinyl group of the conjugated diene block is less than or equal to 45 wt %, or greater than or equal to 60 wt %.
