Publication number: 20130210621Abstract: 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.Type: ApplicationFiled: February 10, 2012Publication date: August 15, 2013Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Vasily A.

Patent number: 8119701Abstract: Disclosed is a method for making polystyrene foam which utilizes one or more atmospheric gases, particularly combinations of HFCs and CO2, as the blowing system in combination with a polymer processing aid (PPA), typically an ester that is relatively non-volatile at the extrusion temperature range. The blowing system and the PPA may both be introduced into the molten thermoplastic polystyrene resin or the PPA may be incorporated in the solid source polystyrene resins. The resulting foams will typically exhibit improved dimensional stability at ambient temperatures.Type: GrantFiled: October 24, 2005Date of Patent: February 21, 2012Assignee: Owens Corning Intellectual Capital, LLCInventors: Yadollah Delaviz, Bharat Patel, Mark Polasky, Raymond M.

Publication number: 20120010307Abstract: The invention provides a composition and process for producing expandable beads from a compostable or biobased thermoplastic polymer. A key aspect of this invention is the ability to incorporate sufficient amounts of hydrocarbon blowing agent into the matrix of the compostable or biobased polymer. The following process may be used. First, the raw materials of compostable or biobased polymers, hydrophobic additive, and other additives are mixed by melt processing techniques. Next, a hydrocarbon blowing agent is added to the admixture, either by addition into the melt or by impregnation into the solid, to produce an expandable bead. Small, lightweight, foamed beads are produced by heating the expandable bead. Then, the expanded beads are subsequently used in conventional operations for molding into foamed articles.Type: ApplicationFiled: July 7, 2011Publication date: January 12, 2012Applicant: Lifoam IndustriesInventors: Adam R.
