In one embodiment, a method of forming an extruded board includes mixing a resin and a foaming agent, melting the mixed resin and foaming agent to form a uniformly colored extrudate, differentially expanding voids formed from the foaming agent within the uniformly colored extrudate by passing the uniformly colored extrudate through a breaker plate, forming a board with the differentially expanded voids and uniformly colored extrudate, and forming lightened portions on an outermost surface of the formed board.

A method for production of an interior unit for a motor vehicle includes production of a support by injection molding, featuring an enclosed front side, wherein at a backside of the support a screw boss is formed whose drill hole is sealed by a support section in the direction of the front side of the support, which support section features a reduced wall thickness in comparison to the remainder of the support, and production of a foam layer on the enclosed front side of the support. Furthermore, the present disclosure relates to an interior unit for a motor vehicle.

Molded foam articles are provided. The molded foam articles are formed from polylactic acid and are capable of a number of post-processing or secondary uses. Forming the molded foam articles from polylactic acid advantageously extend the life of the molded bead foam article by permitting users to cut, heat, adhere, modify, and repurpose the molded foam articles.

Described herein is a process for preparing a foam (FA) with a Poisson's ratio in the range of from −0.5 to 0.3, the method including the steps of providing a foam (F1) with a flow resistance in the range of from 3000 to 8000 Pas/m, determined according to DIN EN 29053, and subjecting the foam (F1) to thermoforming including triaxial compression, wherein the foam (F1) is not reticulated prior to step (ii). Also described herein is the foam obtained or obtainable according to the process and the use of the foam as, for example, an energy absorbing device, preferably in protective gear, furniture, cushions, in cleaning devices with improved rinse-out behavior, in shoe soles, or as sealing, insulating or anchorage providing material for example used in earphones, ear plugs or dowels, or as acoustic material.

Foam wound inserts with high-density and low-density regions, methods for making wound inserts, wound-treatment methods, and wound-treatment systems.

The present disclosure provides a composite material layer including a core layer and a shell layer. The core layer includes foamed elastomers. The shell layer encapsulates the core layer and continuously covered surfaces of the foamed elastomers, wherein the shell layer includes a material having light absorption. The melting point of the core layer is higher than the melting point of the shell layer.

A linear low density polyethylene (LLDPE) foam and methods of making the same are described. The LLDPE foam has a maximum operating temperature of about 220° F. The LLDPE foam can also have a density in the range of from 0.6 to 10.0 lbs/ft.sup.3. The LLDPE foam can be manufactured in part by processing an LLDPE resin in order to create a long branch molecular structure in the LLDPE resin without crosslinking or otherwise adversely affecting the thermoplastic properties of the LLDPE resin.
