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: Optical cable components fabricated from an extrudable polymeric blend of crystalline polypropylene modified with one or more impact-modifying polymers. The impact-modifying polymers are crosslinked and can be selected from a polyolefin elastomer, an olefin multi-block interpolymer, an olefin block composite, and combinations thereof. Optionally, the polymeric blend can further comprise a compatibilizer. The polymeric blend may also contain one or more additives. The optical fiber cable components can be selected from buffer tubes, core tubes, and slotted core tubes.
