Described herein is a multilayer microporous film or membrane that may exhibit improved properties, including improved dielectric break down and strength, compared to prior monolayer or tri-layer microporous membranes of the same thickness. The preferred multilayer microporous membrane comprises microlayers and one or more lamination barriers. Also disclosed is a battery separator or battery comprising one or more of the multilayer microporous films or membranes. The inventive battery and battery separator is preferably safer and more robust than batteries and battery separators using prior monolayer and tri-layer microporous membranes. Also, described herein is a method for making the multilayer microporous separators, membranes or films described herein.

Process for the application of a covering layer to a polymeric product (10), in particular a sheet or a panel, comprising the steps of: —providing a planar substrate (11) of polymeric material, with an ink layer (12) deposited on a surface of said planar substrate (11) to define a printing pattern; —applying, above said ink layer (12), an interface layer in a respective application station (3); —applying a covering layer (14) of transparent polymeric material, above said interface layer and as a protection of the printing pattern in a respective rolling station (4).

A thermal vacuum insulation element (10) comprising a first planar limiting part (12) and a second planar limiting part (14). The limiting parts are spaced apart from each other and define an evacuated space (16) between them. The evacuated space (16) is sealed by means (26) for sealing. The vacuum insulation element includes first support elements (18) extending away from the first limiting part (12) into the evacuated space (16) and second support elements (20) extending away from the second limiting part (14) into the evacuated space (16), the limiting parts (12, 14) being arranged with the support elements (18, 20) such that the first support elements (18) and the second support elements (20) protrude beyond and are spaced from each other. The first support elements (18) are spaced from the second limiting part (14), and the second support elements (20) are spaced from the first limiting part (12). A fiber structure (22) interconnects the first support elements (18) and the second support elements (20). The fiber structure (22) has a low thermal conductivity and is configured to absorb at least the pressure caused by the vacuum on the first and second limiting parts (12, 14).

A roof system comprising a roof substrate, a first membrane including first and second opposed planar surfaces, and a second membrane including opposed first and second planar surfaces, where said second membrane is adhered to said roof substrate through an adhesive disposed on said roof-substrate contacting portion of the first membrane, and where said second membrane is adhered to said first membrane through said adhesive disposed on a lap portion of said second membrane.

The present invention relates to a self-adhesive waterproof coiled material of a super-strong cross laminated film, comprising sequentially from top to bottom: an isolation protection layer, a non-asphalt-based self-adhesive layer, a strong cross laminated film, an asphalt self-adhesive layer and a PE isolation film. One side of the upper surface of the coiled material is provided with an overlap edge, and the other side of the lower surface of the coiled material is also provided with an overlap edge. The waterproof coiled material provided in the present invention has better adhesive property with post-cast concrete than an asphalt-based coiled material, and can be better bonded to a main body structure (i.e., pre-paving anti-sticking coiled material); the strong cross laminated film in the middle of the coiled material has good ductility, so that when the base layer slightly subsides or the main body structure is slightly deformed, the coiled material can continue to be well bonded to the main body structure and would not be separated; and a good waterproof effect thus can be achieved.

The invention relates to a method for producing a composite film with a polyurethane-based reactive hot-melt layer using a coating facility, having the steps of a) optionally applying a primer onto a support material; b) applying the polyurethane-based reactive hot-melt layer onto the primer or directly onto the support material; c) applying a lacquer layer onto the polyurethane-based reactive hot-melt layer in order to produce the composite film on the support material; d) optionally embossing the composite film on the support material; and e) separating the composite film from the support material. The invention additionally relates to a composite film which can be obtained by such a method and to the use thereof.

A pressure sensitive label and method for preparing same, the pressure sensitive label comprising: (a) a support portion, the support portion including at least a carrier layer; and (b) a transfer portion over the support portion for transfer of the transfer portion to an article upon application of pressure while the transfer portion is in contact with the article. The transfer portion may include at least (i) a printable layer in contacting relationship with the carrier layer, and (ii) an ink layer positioned such that the printable layer is between the carrier layer and the ink layer.

A multilayer film comprising, in this order: (a) a biaxially oriented polyethylene terephthalate layer, (b) a pressure sensitive adhesive layer, (c) an elastic polyurethane dispersion, and (d) a biaxially oriented polyethylene terephthalate layer.

Layer (d) preferably has the structure A:B:A:C; where A and B preferably comprise crystalline PET and antiblocking particles and C is preferably an amorphous, heat-sealable copolyester.

A thermo-adhesive multilayer film based on thermoplastic polyurethane includes a barrier layer having a material with anti-dye migration properties selected from: ethylene vinyl alcohol copolymer, polyvinyl alcohol, polyvinyl acetate, polyamides, cellulose derivatives, polyvinylidene chloride and combinations. The barrier layer is interposed between two layers, each having a mixture of a thermoplastic polyurethane with a compatibilizing agent selected from: co-polymers modified with maleic anhydride, co-polymers modified with epoxy groups, co-polymers containing hydroxyl groups and combinations thereof. A decorative multilayer film includes the thermo-adhesive multilayer film and a further decorative layer, which provides an aesthetic effect. A process of co-extruding the layers obtains the thermo-adhesive multilayer film and the subsequent bonding thereof with the decorative layer obtains the decorative multilayer film. The decorative multilayer film decorates substrates in the field of textiles, clothing, footwear and accessories. A finished decorated article includes a substrate on which the decorative multilayer film is applied.
