    Abstract: A breathable film formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure is provided. To achieve such a structure, a thermoplastic composition that contains a renewable polyester and polymeric toughening additive is extruded onto a surface to form a precursor film in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor film is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). Without intending to be limited by theory, the present inventors believe that the deformation force and elongational strain of the drawing process causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This creates a network of voids located adjacent to the discrete domains.

  • Publication number: 20120061867
    Abstract: A process for the manufacture of a plastic part, the process comprising providing a polymer, heating the polymer, introducing a gas or supercritical fluid into the polymer, mixing the polymer and the gas to produce a first melt, extruding the first melt, pelletizing the extruded first melt to form pellets, transforming the pellets into a second melt, and molding the second melt to form the plastic part. In pelletizing the first melt, individual cells of gas are included in the resulting pellets. Before the cells can nucleate, the polymer is solidified to keep the gas contained therein. After the polymer is pelletized, the pellets are considered to be unfoamed. In molding the second melt to form the plastic part, nucleation of the cells is initiated through favorable process conditions and/or additional cell nucleating agents, thereby resulting in the second melt being foamed.

  • Publication number: 20110178194
    Abstract: Provided is a modified blowing agent, wherein the surface of a blowing agent powder is coated with a metallic siloxylated compound. When the modified blowing agent is included in a polymer resin, dispersibility of the modified blowing agent is excellent in the polymer resin and fluidity of the polymer resin is improved in an extrusion molding machine and an injection molding machine, and thus productivity and processability can be improved. In addition, the foam that is formed using the polymer resin composition including the modified blowing agent has excellent tear strength, durability, and masking sound properties due to fine and uniform size of foam cells and increased number of foam cells per unit surface area.
