The present disclosure provides a composition. The composition includes a silane functionalized polyolefin; a flame retardant; and a hindered amine light stabilizer (HALS) having a Mw greater than 5,000 Dalton. The present disclosure also provides a coated conductor. The coated conductor includes a conductor and a coating on the conductor, the coating including a composition. The coating composition includes a silane functionalized polyolefin; a flame retardant; and a hindered amine light stabilizer (HALS) having a Mw greater than 5,000 Dalton.

Polymeric composition containing a light stabilizer

Silane-functionalized compositions comprising a polymeric brominated flame retardant with a weight average molecular weight (Mw) of equal to or greater than (&#x2265;) 1,000 g/mol exhibit improved burn and crush strength properties as compared to silane-functionalized compositions alike in all aspects except that the Mw of the brominated flame retardant is less than (&#x3c;) 1,000 g/mol.

Compositions comprising brominated polymeric flame retardant

Articles made from a moisture-curable, polymeric composition comprising in weight percent based on the weight of the composition:

Flame-retardant, moisture-cured wire and cable constructions with improved glancing impact performance

Articles made from a moisture-crosslinkable, polymeric composition comprising in weight percent based on the weight of the composition: (A) 10 to 99.99 wt % of a nonpolar ethylenic polymer grafted with silane functionality (Si-g-npPE), the npPE having the following properties before grafting: (1) a vinyl content of 0.2 to 0.7 per 1,000 carbon atoms, (2) a melt index of 1.5 to 7.0 dg/min, (3) a density of 0.913 to 0.965 g/cc, and (4) a molecular weight distribution (Mw/Mn) of equal to or less than 8; (B) 0.01 to 20 wt % of a silanol condensation catalyst; and (C) 0 to 70 wt % of a flame retardant additive; exhibit one or more of desirable (a) silane grafting efficiency; (b) hot creep performance as a cable jacket/insulation after moisture crosslinking; (c) retained dielectric strength after glancing impact as a moisture crosslinked cable construction; and (d) crush resistance as a moisture crosslinked cable construction.

The present disclosure provides a composition. The composition includes a silanol functionalized polyolefin; an anhydride-free brominated flame retardant; antimony trioxide; and the composition has an antimony (Sb) to bromine (Br) molar ratio (Sb:Br molar ratio) from 0.37 to 1.05. The present disclosure also provides a coated conductor. The coated conductor includes a conductor and a coating on the conductor, the coating including a composition. The composition includes a silanol functionalized polyolefin; an anhydride-free brominated flame retardant; antimony trioxide; and the composition has an antimony (Sb) to bromine (Br) molar ratio (Sb:Br molar ratio) from 0.37 to 1.05.

Flame retardant polymeric composition

Scorch of a silane-functionalized polyolefin is minimized during melt mixing with a flame retardant through the use of a polydimethylsiloxane (PDMS) having a (1) number average molecular weight (Mn) greater than or equal to (&#x2265;) 4,000 grams per mole (g/mol), (2) viscosity of greater than or equal to (&#x2265;) 90 centipoise (cP), and (3) hydroxyl group content of less than or equal to (&#x2264;) 0.9 weight percent (wt %) based on the weight of the PDMS.

The method of manufacturing a natural ester, oil-based electrical insulation fluid by contacting refined, bleached, optionally winterized, and deodorized natural ester oil, e.g., soy oil, with an absorbent is improved by using as the absorbent a synthetic silicate absorbent comprising an alkali and/or alkaline earth metal, e.g., magnesium.
