Abstract: A die assembly (10) for extruding a polymeric coating onto a wire so as to impart a matte finish to the coating surface is provided. The die assembly (10) comprises: A) a die tip (13) comprising a tubular channel (22) through which a wire can pass, the channel (22) positioned along the central longitudinal axis (26) of the die assembly (10); B) a die body (12) comprising a trunk (15) and a head (16), the head (16) comprising a tubular channel (20), the head tubular channel (20) comprising a die land (21), the trunk (15) positioned about the die tip (13) so as to define an annular space (25) between the exterior surface (23) of the die tip (13) and the interior surface (24) of the trunk (15); C) a die holder (11) positioned about and in contact with the exterior surface (17) of the trunk (15); and D) a radiator (14) positioned about and in contact with the exterior surface (19) of the die land (21) of the die head (16).

Abstract: A composition, preferably a halogen-free, flame retardant composition, comprising in weight percent based on the weight of the composition: A. 1 to 90% TPU polymer, B. 1 to 90% polyolefin polymer, preferably a polar polyolefin polymer, C. 1 to 60% phosphorus-based, intumescent flame retardant, D. 0.5 to 25% liquid phosphate modifier, e.g., bis-phenol-A-polyphosphate, and E. Optional additives and/or fillers. The compositions exhibit excellent strain and scratch whitening performance in combination with excellent burn performance, good flexibility and tensile properties, and good fabrication extrusion characteristics including improved surface smoothness.

Abstract: Halogen-free, flame-retardant thermoplastic compositions that include a styrenic block copolymer, a low-melting, phosphorus-based flame retardant having a melting temperature no higher than 170° C., and a blend of solid intumescent phosphorus and nitrogen-containing flame retardants. The blend of solid intumescent flame retardants include at least two phosphorous and nitrogen-containing phosphoric acid salts that synergistically enhance the flame-retardant properties of the compositions relative to compositions that include other flame-retardant packages.

Abstract: Disclosed is a halogen-free, flame retardant thermoplastic resin composition based on polypropylene and one or more thermoplastic elastomers with an organic nitrogen- and/or phosphorus-based intumescent flame retardant comprising a piperazine component. The composition is processed easily to make a wire and cable sheath exhibiting a balance of high flame retardancy, good flexibility, high wet electrical resistance and excellent heat deformation properties, and which passes the VW-I flame retardancy test, the UL1581 heat deformation test at 150° C. and the wet electrical resistance test, and also exhibits good tensile and flexibility properties. Also disclosed is a wire and cable sheath made from the composition.

Abstract: The present disclosure is directed to a polymeric composition containing a vinyl chloride resin and an epoxidized fatty acid ester. The polymeric composition also includes a heat stabilizing composition. The heat stabilizing composition includes a first metal salt, a second metal salt, and a ?-diketone. The epoxidized fatty acid ester is the primary, or the sole, plasticizer in the polymeric composition. The present polymeric composition finds advantageous application as a coating for wire and cable.

Abstract: Compositions comprising a thermoplastic elastomer, e.g., a polyurethane, a nitrogen and/or phosphorus-based, intumescent flame retardant, e.g., a polyphosphate, a non-phosphorus-based burn synergist, e.g., carbon black or a metal oxide, and an optional olefin polymer, EVA are provided. Color-stable, halogen-free, flame retardant compositions comprising a thermoplastic elastomer polymer, a phosphorus-based flame retardant, at least 3 weight percent TiO2 and a UV stabilizer are also provided.

Abstract: The present invention is a flame-retardant polyurethane composition comprising (a) a thermoplastic polyurethane-based resin component, (b) a phosphorus flame retardant particulate filler, and (c) a low melting temperature phosphorus flame retardant agent.
