PMMA-based rigid foams can be used as the core material of sandwich components in rotor blades of wind power plants and in boatbuilding.

Provided is an electromagnetic dielectric material (1). The electromagnetic dielectric material (1) is a column structure. The electromagnetic dielectric material (1) includes an inner core (11), a first foam layer (12) and a second foam layer (13) sequentially arranged from inside to outside on the cross section of the column structure. The first foam layer (12) and the second foam layer (13) are each a layer formed from a foam material foamed. The electromagnetic dielectric material further includes metal wires (14). The metal wires (14) are disposed in the longitudinal direction of the column structure, are not in contact with each other and are evenly distributed on the periphery of the first foam layer (12). Further provided is a method for producing an electromagnetic dielectric material (1).

The invention relates to a thermally insulated conduit pipe, comprising at least one medium pipe, at least one thermal insulation arranged around the medium pipe, and at least one outer jacket arranged around the thermal insulation, wherein the outer jacket possibly comprises a barrier made of plastic, and wherein the thermal insulation comprises a foam, the cell gas of which contains at least 10 vol % HFOs. Such conduit pipe has good insulating behavior, good environmental balance, and is easily producible.

The invention relates to a bicycle saddle having a saddle shell, on the underside of which a frame is arranged. A saddle pad is arranged on the upper side of the saddle shell. According to the invention, the saddle pad has two padding elements for improved comfort, wherein in a preferred embodiment the inner padding element is made of TPU (thermoplastic polyurethane).

A method for producing a filter element provided with a sealing part in which the sealing material is introduced into a casting chamber between two tundish parts when in the non-cured state, and a compensation space connected to the casting chamber for the expansion of the sealing material.

The present disclosure relates to a seat element, in particular, a headrest for a vehicle seat, the seat element comprising at least one support bar made of metal, a first layer provided at an exterior surface of the support bar, and a cushion made of an upholstery material. Hereby, the first layer is formed by blowing on first fibers made of plastics which are thermally welded directly or indirectly to the exterior surface.

At least part of the first fibers extends away from the exterior surface and/or the first layer towards the outside into the upholstery material and is thermally cross-linked with the upholstery material, in particular, blown-on further fibers.

A device for machining a cover for a motor vehicle may have a lower mold having a sealing element and a first recess and a second recess a distance from the first recess. The sealing element is arranged in part in the first recess of the lower mold so that the element extends with respect to a surface of the lower mold. The sealing element and the second recess of the lower mold are formed so as to define a cavity in a predefined manner in cooperation with a lower face of the cover. The device further may have a counter bearing which is designed, when forming the cavity on the lower face of the cover, to exert a counter force on an upper face of the cover towards the lower mold.

There is provided a skin foam-in-place foamed article comprising a pad (15) and a bag-like outer material (20) covering the pad (15). The outer material (20) has a top layer (21) and a liner layer (22) made of a foamed resin. The liner layer (22) has a closed cell structure. A pad-side skin layer (27a) having a density higher than that of a bulk layer (26) is provided on the liner layer (22), on a side of the pad (15). A corona treatment is applied to the pad-side skin layer (27a).

The invention relates to a sound protection panel for cladding a wall of an automotive vehicle, the panel includes a mass-spring system. The panel has a lower spring layer based on a resiliently compressible material, an upper mass layer based on resiliently compressible foam flakes, the flakes being bound together by a two-component fibre-based bonding agent comprising a core. The core is fusible at a high temperature or infusible, and a sheath fusible at a lower temperature, the flakes being fused with the sheath to form an upper agglomerated layer.
