A composite element for the realization of protection devices of parts of the human body includes a matrix, a reinforcing element, at least partially embedded in the matrix, wherein the reinforcing element has at least one opening shaped so as to define an undercut between the matrix and the reinforcing element, such undercut being suitable for determining a mechanical constraint between the matrix and the reinforcement element.

Hot melt adhesives with pressure sensitive adhesive properties for electronic devices are described. The hot melt adhesive comprises a styrenic block copolymer with fully hydrogenated and saturated soft blocks, a liquid diluent or a tackifier, a (meth)acrylate monomer or an oligomer having at least two (meth)acrylic functionalities per oligomer chain, and an initiator. The hot melt adhesive is also a reworkable UV curable optically clear adhesive film. The adhesive and film are suitable as a laminating PSA film or encapsulant for LCD display, LED display, touch screen, and flexible thin film photovoltaic module.

A subsea well equipment landing body (1) comprising an indicator assembly to indicate landing of the landing body or to indicate locking of the landing body. The indicator assembly has a stem bore (7), a sliding stem (11) within the stem bore that has a stem head (23) protruding beyond an external face of the landing body. A stem channel (25) in the sliding stem extends between the stem head and a stem channel mouth (27), and is in fluid communication with the outside of the landing body. A hydraulic channel (9) in the landing body is in fluid communication with the stem bore. The stem channel mouth is positionable in a communicating position, in which there is fluid communication between the hydraulic channel and the stem channel, and a non-communicating position, without fluid communication between the hydraulic channel and the stem channel.

A resin composition according to the present invention contains a cyanate compound (A). Further, the resin composition according to the present invention contains a maleimide compound (B) and/or an epoxy resin (C); and primary hexagonal boron nitride particles (D) having an average aspect ratio of 4 to 10.

A cover tape includes first and second basal layers, a first adhesive layer having a low peeling-strength and disposed between the first and second basal layers, and a second adhesive layer having a high peeling-strength and disposed on the other surface of the second basal layer. The cover tape adheres to two ends of a carrier tape. Two vertically-extending notches are disposed at two ends of the second basal layer and correspond in position to points of coupling to the carrier tape, respectively. Defined on the second basal layer are a centrally-located central release portion and fixing portions disposed at two ends of the second basal layer. Peeling off the cover tape entails separating the first basal layer from the two fixing portions of the second basal layer under a stable, small pulling force and separating the central release portion and the first basal layer from the carrier tape.

A hot tub cover consists of an impermeable exterior shell and at least one multilayered insulative and structural core. Each multilayered insulative and structural core may further have multiple core layers layered adjacent to each other in various configurations, providing superior protection from heat losses from within the hot tub as well as structural strength and durability.

A multi-layer foam sheet with an apparent density of 30 to 300 kg/m.sup.3 and a thickness of 0.05 to 2 mm, including a foam layer containing a polyethylene-based resin, and an antistatic layer fusion-laminated by coextrusion on each of both sides of the foam layer. The antistatic layer has a basis weight of 1 to 10 g/m.sup.2 and contains a polyethylene-based resin, a polystyrene-based resin, a styrenic elastomer, and a polymeric antistatic agent, with the polystyrene-based resin being contained in the antistatic layer in an amount of 15 to 70% by weight.

The multilayer foam sheet has a surface resistivity of 1?1013? or less and has a foam layer and resin layers that are laminated on both surfaces of the foam layer. The resin layers each have a multilayer structure formed from a surface layer and an intermediate layer that is positioned between the surface layer and the foam layer. The foam layer includes a polyethylene-based resin PE2. The intermediate layers are configured from an antistatic mixture containing a polyethylene-based resin PE3 and a polymeric antistatic agent. The surface layers are configured from a mixed resin containing a polyethylene-based resin PE4 and a polystyrene-based resin, and substantially do not contain the polymeric antistatic agent. The polystyrene-based resin content of the mixed resin is 3-35 wt %.

Provided herein are multilayer polymeric interlayers comprising ionomers and acoustic damping compositions, and glass laminates made from them, which provide an improved combination of hurricane resistance, acoustic damping properties and, optionally, solar barrier performance.
