Abstract: Disclosed is an effective thermal grease comprising a hyperbranched olefinic fluid and a thermally conductive filler. Property- modifying additives and fillers may also be included. The hyperbranched olefinic fluid is selected to have an average of at least 1.5 methine carbons per oligomer molecule and at least 40 methine carbons per one thousand total carbons. The thermal grease exhibits a flash point of 180 °C or higher, a pour point of 0 °C or lower, and a kinematic viscosity at 40 °C of no more than 200 cSt (0.0002 m 2/s). The composition may offer improved thermal conductivity, reduced tendency to migrate, and lower cost when compared with many other thermal greases, including silicone-based thermal greases.

Abstract: A method of making a homogeneous mixture of polyolefin solids and carbon solids without melting the polyolefin solids during the making. The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the carbon solids for a period of time sufficient to substantially intermix the polyolefin solids and the carbon solids together while maintaining temperature of the heterogeneous mixture below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids.

Abstract: Articles of manufacture containing an extrusion-foamed polymeric composition. The extrusion-foamedpolymeric composition contains an ethylene-basedpolymer and an olefin-based elastomer. The extrusion-foamed polymeric composition can be prepared from a foamable polymeric composition containing the ethylene-based polymer, the olefin-based elastomer, a nucleating agent, and a blowing agent. The extrusion-foamed polymeric composition can be prepared using an extrusion foaming process.

Abstract: The present disclosure provides a process. In an embodiment, the process includes blending a broad molecular weight distribution (MWD) ethylene-based polymer having an 121/12 ratio from 55 to 85 with a narrow MWD ethylene-based polymer having an 121/12 ratio from 20 to 50. The process includes forming a blend component comprising from 20 wt% to 45 wt% of the broad MWD ethylene-based polymer, from 80 wt% to 55 wt% of the narrow MWD ethylene-based polymer, and optional carbon black. The blend component has a density from 0.925 g/cc to 0.955 g/cc and an 121/12 ratio from 30 to 55. The process includes extruding the blend component over a conductor at a rate greater than 1.02 m/s, and forming a conductor jacket having a surface smoothness from 30 µ-inch to 80 µ-inch.

Abstract: La presente invención se refiere a materiales térmicamente conductores que comprenden un elastómero no polar, un elastómero polar, y un rellenador térmicamente conductor. El elastómero polar y elastómero no polar son suficientemente inmiscibles para formar una fase elastomérica polar y una fase elastornérica no polar. El rellenador térmicamente conductor está concentrado en una cantidad de al menos 60 porciento en volumen de la cantidad total del rellenador en ya sea la fase del elastómero no polar o la fase elastomérica polar. El material térmicamente conductor tiene un módulo de elasticidad a la tracción menos de 200 MPa.
