A resistor grid system includes a resistor strip including multiple pins. The resistor grid system also includes an insulation board coupled to the resistor strip through the multiple pins and configured to provide a structural support. The insulation board is made of a composite material. The composite material includes a nitrogen-containing aromatic thermosetting polymeric resin and a filler.

An optical sheet is formed by laminating, by co-extrusion molding, a first layer containing a polycarbonate resin, a second layer containing a polyamide resin, and a third layer, wherein the second layer is laminated between the first layer and the third layer, the first layer and second layer, and the second layer and third layer can each be peeled at the interface, and the outer surface of the first layer has a fine grooved structure. The optical sheet, which is provided with a plurality of layers in such a way, is capable of retaining, a sufficient amount of heat in a laminate in a mold since the entire sheet can be made thick during melt extrusion molding, and is able to improve the transferability of the fine grooved structure. In addition, the optical sheet can be made thinner by using only the peeled first layer as an optical sheet.

There is provided an adhesive composition comprising at least 50 wt % of an aqueous dispersion of an amorphous polyurethane having a Tg below 25° C.; and a water dispersible cross-linker, where the adhesive composition has a peel retention of greater than or equal to 5% according to the Water/IPA Exposure Test.

A multi-layer biaxially oriented polypropylene (BOPP) film with a novel formulation which exhibits matte appearance is disclosed. This improved formulation comprises a blend of high density polyethylene (HDPE), medium density polyethylene (MDPE), low density polyethylene (LDPE) or linear low density polyethylene (LLDPE) with polypropylene (PP) used in the core layer to achieve a matte appearance low gloss PP-based film that still exhibits typical properties of BOPP films with significantly lower haze than conventional matte films. The multi-layer BOPP film has additional layers such as a second polyolefin resin-containing layer, a metal layer, or combinations thereof.

A nonwoven composite that exhibits latent elastic properties is provided. The composite is formed from a multi-layered, elastic film laminated to a nonwoven web facing. Latent elasticity is imparted to the composite through the use of at least one base layer that contains a thermoplastic elastomer and at least one skin layer that contains a propylene/α-olefin copolymer. During formation, the film is stretched in one or more directions to orient the elastomer chains. Without intending to be limited by theory, the present inventors believe that the oriented state of the chains may be held in place by the relatively stiff semi-crystalline domains of the propylene/α-olefin copolymer. The stretched elastic film may subsequently be relaxed and bonded to a nonwoven web facing to form the composite. The composite may be later activated (e.g., heated at or above the softening point of the copolymer) to soften the crystalline domains and allow the chains to return to their unoriented state. This causes the film to retract, which forms buckles in the nonwoven facing. In this manner, the resulting composite becomes elastic in that it has the ability to stretch and recover due to the “latent” buckle formation in the nonwoven facing.

A multi-layer biaxially oriented polyester (BOPET) film having at least one BOPET film layer and at least one coating layer comprising a polyester polymer and particles that are partially or fully embedded in the coating layer is described herein. The particles have an average particle size of about 4 to 8 microns, the coating layer has a gloss of 25 GU or less measured by a 60 degree glossmeter, and the paint adhesion crosshatch test value of the BOPET film as per ASTM D3359-09 is 10% or less.

An adhesive composition contains a block copolymer hot melt adhesive and a vapor releasing vapor corrosion inhibitor mixed with the block copolymer hot melt adhesive, the vapor corrosion inhibitor being in the form of particles suspended in the adhesive composition, the particles preferably having a maximum dimension of less than about 30 microns. One improvement results from inclusion in the adhesive mixture of a titanium and/or zirconium containing coupling agent, either separately or as part of the VCI particles. Another improvement results from blending the adhesive mixture in a continuous process using for example a twin screw extruder. As a result, the adhesive mixture has better uniformity and superior viscosity properties during use.

According to one embodiment, an adhesive tape includes a film and an adhesive layer. The film includes polytetrafluoroethylene and a carbon filler. The adhesive layer is provided on a surface of the film, and includes a silicone pressure-sensitive adhesive.

A thermoformable decorative material for an automotive interior includes: a decorative layer including a textile substrate; a digitally printed design disposed on at least one side of the textile substrate and having dispersion ink and/or pigment ink; and an overlay adhesive coating applied to the digitally printed design. The overlay adhesive coating has an adhesive that includes polyurethane and/or polyacrylate.

Embodiments herein relates to a Bisphenol A-free multi-layer biaxially oriented polyester (BOPET) film, for lamination on metal sheets, which could be used for food containers. The BOPET film has at least one outer release layer, which aids in the release of food, such as a high protein food source, when food is cooked and sterilized in direct contact with the outer release layer. The BOPET film can be laminated to metals used in the manufacture of food containers with the outer release layer being exposed to allow a direct food contact between the surface of the outer release layer and food. More particularly, the invention relates to a novel outer release layer resin composition comprising an ultra high molecular weight siloxane polymer and a polyethylene trephthalate resin; and an alkali-metal phosphate and a phosphoric acid compound added, during polymerization of the outer release layer resin composition, as a catalyst/additive package to the ingredients forming the outer release layer resin composition. A wax component is added in the outer release layer, for more robust release performance.
