Abstract:
Filled polyurethane foams having tailored microstructures, as well as methods of making these polyurethane foams, are described herein. By tailoring the microstructure of the polyurethane foam, composite materials having desirable mechanical properties (e.g., elastic modulus, compressive strength, or combination thereof) can be obtained.
Abstract:
The invention provides a composition comprising at least one olefin multi-block interpolymer; at least one functionalized olefin-based polymer; and optionally at least one thermoplastic polyurethane. The invention also provides for articles prepared from the inventive compositions and for methods for making the same.
Abstract:
Panel systems and related methods of controlling sound transmission are discussed. For example, the panel system may include a sound control component, which may include a foam composite of a polymer and an inorganic filler. The panel system may further include an attachment mechanism, e.g., including at least one fastener, at least one bracket, and/or at least one rail or rail system. The attachment mechanism may be configured to secure the sound control component between a first wall and a second wall, such that the panel system controls sound transmission between the first and second walls.

Abstract:
The present disclosure is directed to a halogen-free composition and conductors coated with the halogen-free composition. The halogen-free composition includes (A) from 70 wt % to 85 wt % of a polymeric component and (B) from 30 wt % to 15 wt % of a halogen- free flame retardant. The polymeric component (A) includes (i) a propylene homopolymer or a mini- random copolymer with greater than 40% crystallinity and (ii) an ethylene/a-olefin copolymer. The halogen-free composition has a density less than 1.15 g/cc. The halogen-free composition also has a scrape abrasion resistance of greater than or equal to 350 cycles as measured in accordance with ISO 6722.
Abstract:
Net-shape composites and methods of manufacturing are described herein. The method of preparing net-shape composites may include combining a first semi-solid component with a second semi-solid component to form a polymer composition, and forming the polymer composition into the net-shape composite, wherein each of the semi-solid components has a yield stress of at least 50 Pa. The first semi-solid component may include a first portion of a filler, and the second semi-solid component may include a second portion of a filler that is the same or different than the filler of the first semi-solid component.
Abstract:
A composition comprising (A) at least one bisphenol-A polycarbonate resin, (B) at least one polypropylene, preferably a high crystallinity polypropylene, (C) at least one compatibilizer comprising an amine functionalized elastomeric polymer, (D) at least one organic phosphate flame retardant, preferably an organic phosphate that is liquid at room temperature, and, optionally, (E) one or more additives. These compositions are useful in the manufacture of wire insulation coatings of less than 0.2 mm with good scrape abrasion resistance.
Abstract:
A process is described for determining elastic modulus, plastic yield strain, and viscosity of a material, and the work of adhesion between the material and an indenter tip, using Atomic Force Microscopy-based or conventional nanoindentation. Specifically, the process includes a measurement method whereby a sequence of load-unload quasistatic indentations are performed in the vicinity of each chosen point on a sample. The loading- unloading curves are analyzed using a specific modeling algorithm to calculate multiple mechanical properties of the sample.
Abstract:
A tablet, pill or capsule containing a material which produces sound waves when the tablet, pill or capsule is exposed to the gastrointestinal system. A two step method for oral drug compliance monitoring. The first step is to ingest a tablet, pill or capsule containing a material which produces sound waves when the tablet, pill or capsule is exposed to the gastrointestinal system of a person. The second step is to detect the sound waves produced when the tablet, pill or capsule is exposed to the gastrointestinal system to confirm that the person has ingested the tablet, pill or capsule.
Abstract:
Shapeable composites and methods of use and manufacturing are described herein. The shapeable composites may include a polymer and a functional filler, e.g., the functional filler present in an amount greater than or equal to 40% by weight, based on the total weight of the shapeable composite. The shapeable composite may be a foam composite having a viscoelasticity, such that the shapeable composite is configured to be reshaped.
