This disclosure relates to a composite comprising (a) a rubber layer comprising a cured rubber and optionally a first copolymer having carboxyl groups or anhydride groups; and (b) a foam layer comprising a crosslinked ethylene vinyl acetate and optionally a second copolymer having carboxyl groups or glycidyl methacrylate groups; wherein the foam layer has at least one surface adhering to the rubber layer directly, and provided that either the first copolymer or the second copolymer is present, and the composite is free of glues or adhesive films in the interface between the rubber layer and the foam layer.

A floor plank having a rigid, composite core having an upper side and a underside, the core being thermally stable and formed of PVC and calcium carbonate material that does not include ortho-phthalates, a wood veneer having a lower surface on the upper side of the core and further including an exposed surface, a protective coating on the exposed surface of the wood veneer, the protective coating formed of catalyzed polyurethane having aluminum oxide particles, and a thermo-acoustic cushion coating on the back surface of the core. A method of making is also provided.

An acoustic composite comprising a plurality of discrete air flow resistive layers layered on top of each other including a top layer and one or more lofted fibrous layers produced by a lapping process, the top layer having a specific air flow resistance that is greater than a specific air flow resistance of the one or more lofted fibrous layer.

A surface covering is provided and includes an upper section of laminated polymeric layers and an acoustical section for dissipating sound waves.

The present invention is directed to an acoustical baffle that has use in vehicle interiors, such as an interior headliner. In particular, the baffle can provide improved acoustics while maintaining a desired airflow resistance and can be configured to provide for different sound attenuation characteristics at selected locations of the baffle construction.

The present invention is directed to an acoustic ceiling panel having a first major exposed surface opposite a second major exposed surface, the acoustic ceiling panel comprising: a first layer having an upper surface opposite a lower surface, the first layer comprising: a first body comprising a first major surface opposite a second major surface and a side surface extending between the first and second major surfaces, the first body being air-permeable; and a first attenuation coating applied to the first body; a second layer having an upper surface opposite a lower surface, the second layer comprising: a second body comprising a first major surface opposite a second major surface and a side surface extending between the first and second major surfaces, the second body being air-permeable; and a second attenuation coating applied to the second body; and an adhesive present between the first and second layers.

A waterproof sound-transmitting sheet, which interposes an adhesive layer composed of a material having micropores formed therein, thus smoothing the flow of the air between a waterproof sound-transmitting layer and a support layer. The waterproof sound-transmitting sheet includes a waterproof sound-transmitting layer formed of a film having elasticity, an adhesive layer having one surface adhered to one surface of the waterproof sound-transmitting layer, and a support layer having one surface adhered to the other surface of the adhesive layer; and the adhesive layer includes a substrate having a pore formed therein and an adhesive agent formed on both surfaces of the substrate.

Flooring and floor panels are described that include a multi-layer tape. The multi-layer tape can include two or more layers at least one of which can include a unidirectional orientation of fibers. In some configurations, the panels can include a tape with multiple layers where each layer of the tape includes a unidirectional orientation of fibers, which may be the same or may be different. Vehicles and other devices including the panels are also described.

Multiple layer interlayers having enhanced optical and acoustic properties are provided, along with methods of making and using the same. Interlayers as described herein may include at least two outer skin layers and an inner core layer, with one of the outer skin layers having a different thickness than the other at one or more locations along the interlayer. The multi-layer interlayer may also exhibit acoustic properties and, in some cases, may have an overall wedged thickness profile. Additionally, in some aspects, interlayers and laminates formed therefrom may also provide reduced infrared energy transmission, without sacrificing acoustic and/or optical performance.
