Abstract: Organoclays are added to semiconductive compositions to provide a reduction in the dielectric losses of layered composites in which the semiconductive layer contains species which could migrate into the insulation and result in undesirably high dielectric losses. The invention semiconductive compositions provide improved performance in power cable applications.

Abstract: The present invention is a flame-retardant polyolefin/thermoplastic polyurethane formulation made from or containing a polyolefin, a thermoplastic polyurethane, and an intumescent, polyphosphate flame retardant composition. The invented system achieves elongations >400% and tensile strengths >1500 psi while the same polyolefin only achieved 100% elongation and <1000 psi tensile strength. Also, the present invention shows improved tape extrusion performance versus a comparable TPU only composition, indicating improved melt rheology/fabrication capability for extrusion applications.

Abstract: Plasticizers are made from oil with a narrowed, fatty acid polydispersity and extracted from a microorganism, such as a natural or genetically modified bacterium or algae. These plasticizers can comprise either a large content of either saturated C4 and/or C6 triglycerides or unsaturated C12 or greater triglycerides that have been chemically modified by one or more of epoxidation, acylation and esterification. The plasticizers of this invention are particularly well-suited for use with polar polymeric resins such as PVC.

Abstract: TRXLPE-type cable sheaths are prepared by a method in which a solid polymer is mixed with a liquid water tree-resistant agent either by dosing or direct injection. In the dosing method, the solid polymer, e.g., high pressure LDPE, is sprayed or otherwise contacted with the liquid agent, e.g., PEG, the agent is allowed to absorb into the polymer, and the polymer with absorbed agent is then fed to an extrusion apparatus for extrusion over a sheathed or unsheathed wire or optic fiber. In the direct injection method, the solid polymer is first fed to an extrusion apparatus, and the liquid agent is sprayed or otherwise contacted with the polymer before the two are blended with one another through the action of the mixing elements of the apparatus.
