Abstract
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.
Claims5
A composition comprising:
- 20 wt % to 80 wt % of a silane functionalized polyolefin based on a total weight of the composition, wherein the silane functionalized polyolefin comprises 1.0 wt % to 5.0 wt % silane based on the total weight of the silane functionalized polyolefin;
- 5 wt % to 40 wt % of a halogenated flame retardant or 20 wt % to 70 wt % of a halogen-free flame retardant based on a total weight of the composition;
- and
- 0.1 wt % to 0.5 wt % a hindered amine light stabilizer (HALS) based on a total weight of the composition, wherein the HALS has a weight average molecular weight, Mw, greater than 5,000 Dalton (g/mol), further wherein the HALS has a Structure (H):
- wherein m is an integer from 3 to 20, wherein the composition yields a wet insulation resistance (IR) ratio from 0.4 to 20.0.
