A coagent masterbatch comprising a semi-crystalline polyolefin carrier resin and an alkenyl-functional coagent. An electron-beam curable formulation comprising the coagent masterbatch and a polyolefin compound. A method of making the masterbatch and formulation; an electron-beam-cured polyolefin product prepared therefrom; a manufactured article comprising or made from the masterbatch, formulation, or product; and a method of using the manufactured article.

Masterbatch with semi-crystalline polyolefin carrier resin

A coagent masterbatch comprising a semi-crystalline polyolefin carrier resin and an alkenyl-functional coagent. A peroxide curable formulation comprising the coagent masterbatch and a polyolefin compound. A method of making the masterbatch and formulation; a peroxide-cured polyolefin product prepared therefrom; a manufactured article comprising or made from the masterbatch, formulation, or product; and a method of using the manufactured article.

An (electron beam)-curable (EBC) formulation comprising an EBC polyolefin compound having a crystallinity of from 0 to less than 50 weight percent (wt %) and/or having a density of 0.930 gram per cubic centimeter (g/cm) or less; and an alkenyl-functional monocyclic organosiloxane ('silicon-based coagent'). Also included are a cured polyolefin product prepared by electron-beam irradiating the EBC formulation; methods of making and using the EBC formulation or cured polyolefin product; and articles containing or made from the EBC formulation or cured polyolefin product.

A die assembly () for extruding a polymeric coating onto a wire so as to impart a matte finish to the coating surface is provided. The die assembly () comprises: A) a die tip () comprising a tubular channel () through which a wire can pass, the channel () positioned along the central longitudinal axis () of the die assembly (); B) a die body () comprising a trunk () and a head (), the head () comprising a tubular channel (), the head tubular channel () comprising a die land (), the trunk () positioned about the die tip () so as to define an annular space () between the exterior surface () of the die tip () and the interior surface () of the trunk (); C) a die holder () positioned about and in contact with the exterior surface () of the trunk (); and D) a radiator () positioned about and in contact with the exterior surface () of the die land () of the die head ().

Agglomerated fine solids, e.g., agglomerated pellets (B), that are located within a restricted space or pinch point of a conveyance system (), and that impede the free-flow of fine solids from one vessel () to another vessel (), are detected and fragmented through the coordinated use of a flow detector (), breaker plate () and press (). The flow detector () senses an interruption or diminishment in the flow of the fine solids and signals and actuates the press () which in turn engages and fragments the agglomeration. The breaker plate () is sized and configured to trap major agglomerates.
