A curative for epoxidized plant-based oils and epoxidized natural rubber is created from the reaction between a naturally occurring polyfunctional acid and an epoxidized plant-based oil is disclosed. The curative may be used to produce at least one of six different materials, wherein each type of material may be configured as a thermosetting elastomer that is crosslinked with β-hydroxyester linkages. The materials may be configured as a leather-like material, a foam material, a molded elastomer, a coating, an adhesive, and/or a rigid or semi-rigid material. Illustrative articles made from any combination of the six materials may be recycled using a mechano-chemical process to de-crosslink the thermosetting elastomer.

A method of manufacturing a composite panel with lauan or another moisture-carrying or moisture-absorbing material, and the panel so made, are provided. A layer of gel coat is formed on a mold surface, a wet laminate containing a resin is applied to the layer of gel coat on the mold surface, a substrate of lauan or another moisture-carrying or moisture-absorbing material is placed on the wet laminate, and the combination is cured. Prior to curing, there is provided a layer of a bonding promoter at the interface of the substrate with the wet laminate, additional to any amount of promoter(s) present in the resin of the wet laminate.

A multilayer plate, comprising a layer composed of a methacrylic resin comprising not less than 90% by mass of a structural unit derived from a methacrylic acid ester such as methyl methacrylate, methacrylic esters of a polycyclic aliphatic hydrocarbon and the like and having a glass transition temperature of 120 to 180° C., and a layer composed of a polycarbonate resin.

A method for the production of grounded panels and to a panel having a core made from a wood material board. The method includes provision of a wood material board, application of a grounding in the form of a synthetic resin layer to at least one topside of the wood material board, application of a coating to an underside, lying opposite the topside of the wood material board, of the wood material board, pressing of the layer build-up consisting of the wood material board, grounding and coating under the influence of pressure and, if appropriate, temperature, division of the grounded and coated wood material board into individual panels, cutting machining of side faces of the panels for the incorporation of connection and locking means, and transport-safe packaging of the grounded panels.

A composition includes 100 parts by weight of poly(alkylene terephthalate) and 0.01 to 2 part by weight of a compound represented by Formula (1), a partially saponified derivative thereof, or a combination thereof, (1) wherein R.sup.1, R.sup.2, and n are defined herein. The composition, which excludes copolymers of an unsubstituted or substituted styrene and an unsaturated nitrile, is useful for molding articles with very smooth surfaces. For example, the composition can be used to mold directly-metallizable substrates for automotive headlight reflectors and bezels.

A multi-layer shrink film comprising, consisting of, or consisting essentially of at least two layers, Layer A and Layer B, wherein Layer A is at least one skin layer comprising an amorphous glassy polymer material and Layer B is at least one core layer comprising i) 15-100 weight percent of a maleic anhydride-modified plastomer having a density in the range of 0.86-0.925 g/cm.sup.3; and ii) optionally a polyolefm which does not contain maleic anhydride having a density in the range of 0.86-0.925 g/cm.sup.3 and wherein the multi-level shrink film has an overall density of less than 1.0 g/cm.sup.3, is disclosed.

Multi-layer films and labels are disclosed herein. In an embodiment, a multi-layer film comprises a first skin layer, a first intermediate layer, a core layer, a second intermediate layer, and a second skin layer arranged sequentially, wherein the core layer has a thickness that is greater than thickness of the first or the second intermediate layers or the skin layer, wherein the core layer includes polybutylene terephthalate (PBT) particles disposed therein, wherein the amount of PBT particles ranges from about 5 to about 10 percent by weight (wt %), based on the total weight of the core layer, wherein the multi-layer film has a thickness ranging from about 25 microns to about 45 microns, wherein the core layer has a thickness ranging from about 20 microns to about 40 microns.

The present application relates to a polycarbonate composite article, a preparation method therefor, and use thereof. The polycarbonate composite article includes a foamed polycabonate layer and a non-foamed polycarbonate film layer on the foamed polycarbonate layer. The polycarbonate composite article according to the present invention has a reduced weight and improved signal penetration performance, and can be used as an antenna housing.

A modular utility vehicle construct that is light weight yet robust is provided. The construct is formed with a composite open area core sandwich structure capable of withstanding typical wear and tear and environmental elements experienced by utility vehicle compartments. The use of the composite sandwich structure allows for replacement of traditional materials such as steel or aluminum, without a loss of strength, in a vehicle's containment construct while also reducing the overall weight of the vehicle and increasing the ability to customize the vehicle's utility features to suit the specific needs of the purchaser.

A compostable laminate for food wrap and method for making same. The wrap can include a first layer of paper material, a second layer of paper material, and a series of coatings between the paper materials. The coatings include a first flood coating having water and/or barrier properties, a second flood coating having water and/or oil barrier properties, and a third coating that only partially covers the second flood coating. None of the first, second and third coatings comprise a thermoplastic or polyolefin, and are made substantially from one or more biodegradable and/or compostable materials.
