The invention relates to a sound protection screen with an external shell made of a moulded thermoplastic material, an internal sub-layer based on resiliently compressible moulded polyurethane foam. The sub-layer is over-moulded with the rear side of the external shell. by over-moulding The shell is based on a sheet of thermoformed thermoplastic material and has a thickness between 0.2 and 1 mm. The shell can be a two-layered shell, with an external layer based on polyolefin. The external layer having at the side of the sub-layer, in order to allow adhesion between the shell and the sub-layer, with a rear layer based on a thermoplastic material that adheres to the foam. The shell can also be a single layer based on polyolefin, the rear side being subjected to a surface treatment that allows the adhesion to the sub-layer to be improved.

The present invention provides a continuous process for solid-state expansion of a biopolymer, e.g., polylactic acid, which can be used to manufacture reduced-density thermoplastic materials with improved physical and thermal properties. By incorporating multiple stages of heating into the process as a means to regulate heat flux, unprecedented control of microstructure and crystallinity can be achieved. Thermoplastic sheets with the distinct cellular characteristics imparted by the process disclosed herein were found to be thicker and stronger than materials prepared by conventional processes. Thermoforming sheets with such characteristics enabled the production of light-weight, thermally-stable, compostable products that resist warping, and are thus suitable for a range of industrial applications.

Example embodiments described in this disclosure are generally directed to a mounting bracket for deployment in a vehicle. In one embodiment, a multilayer mounting bracket includes a first layer made of a dual-conductive polymer and a second layer made of a polymer that includes an endothermic blowing agent. The dual-conductive polymer includes carbon material that renders the first layer electrically conductive and also includes graphite material that renders the first layer thermally conductive. The endothermic blowing agent renders the second layer thermally insulative. An electronic module such as an engine controller can be mounted upon the first layer, which operates as a heat sink to dissipate heat generated by the electronic module and also operates as an electromagnetic interference (EMI) shield. The second layer prevents heat from being transferred from the first layer into another electronic module that may be mounted upon the mounting bracket.
