摘要： A method for producing a foam-molded product by using a plasticizing cylinder, includes: plasticizing and melting the thermoplastic resin to provide the molten resin in a plasticization zone of the plasticizing cylinder; introducing a pressurized fluid containing the physical foaming agent at a fixed pressure into a starvation zone of the plasticizing cylinder to retain the starvation zone at the fixed pressure; allowing the molten resin to be in the starved state in the starvation zone; bringing the molten resin in contact with the pressurized fluid containing the physical foaming agent at the fixed pressure, in the starvation zone in a state in which the starvation zone is retained at the fixed pressure; and molding the molten resin having been brought in contact with the pressurized fluid containing the physical foaming agent into the foam-molded product.

摘要： The present invention relates to multi-layered composite structures and to methods for the preparation thereof. The present multi-layered composite structures are light weight and capable of high load bearing making the present multi-layered composite structures especially suitable to be used as load bearing structures in, for example, automotive. Specifically, the present invention relates to methods comprising the steps of a) providing a mould for said multi-layered composite structure; b) layering said mould with two or more layers forming the outer surface of said multi-layered composite; c) filling said layered mould with a mixture comprised of non-expanded heat-expandable microspheres and closing said mould; and d) subjecting said closed mould to a temperature of 80° C. to 140° C. during 1 to 230 minutes thereby providing a relative pressure in said closed mould of 0.1 to 20 bar through expansion of said heat-expandable microspheres thereby forming a multi-layered composite structure in said mould with a foam enforced inner core and a multi-layered outer surface; and e) separating the multi-layered composite structure from said mould.

摘要： Devices and methods for making a polymer with a porous layer from a solid piece of polymer are disclosed. In various embodiments, the method includes heating a surface of a solid piece of polymer to a processing temperature and holding the processing temperature while displacing a porogen layer through the surface of the polymer to create a matrix layer of the solid polymer body comprising the polymer and the porogen layer. In at least one embodiment, the method also includes removing at least a portion of the layer of porogen from the matrix layer to create a porous layer of the solid piece of polymer.

摘要： Method of forming an article from a molten plastic composition including a polymer and a blowing agent. The method provides that during an injecting step (c) and a packing step (d), the injection pressure and the packing pressure, respectively, are maintained above a minimum pressure threshold in at least one second region of the cavity to maintain the physical blowing agent as a gas dissolved in the polymer so that substantially no gas bubbles are formed in the at least one second region, during a mould opening step (e), at least some of the molten plastic composition is exposed to an external pressure lower than a minimum pressure threshold to form in the article at least one first portion having expanded cellular foam formed from the plastic composition, and prior to the opening step (e), the plastic composition in the at least one second region of the cavity has been cooled so as to be fully solidified to form in the article at least one second portion having a substantially homogeneous, solid phase, unexpanded plastic composition
