Abstract

A non-halogenated flame retardant thermoplastic compound is disclosed. The compound comprises one or more grafted polyolefin resins, non-halogenated flame retardant, non-halogenated processing aid, a compatibilizer, and, optionally, other additives. The non-halogenated processing aid found to be useful, among several candidates, was a dendritic polymer.

Claims (15)

1. A non-halogenated thermoplastic composition, comprising:

(a) grafted polyolefin;

(b) non-halogenated flame retardant;

(c) dendrimer having CAS Registry No. 326794-48-3; and

(d) a maleic anhydride modified polyolefin.

2. The composition of claim 1 , wherein the grafted polyolefin is the reaction product of a polyolefin resin and a polyfunctional organosilane in the presence of an initiator.

3. The composition of claim 2 , wherein the polyolefin is a polyethylene homopolymer or copolymer and wherein the polyfunctional organosilane is vinytrimethoxy silane or vinyltriethoxy silane.

4. The composition of claim 3 , wherein the non-halogenated flame retardant is selected from the group consisting of aluminum trihydrate, magnesium dehydrate, hydrotalcite, zinc borate, a phosphorus-nitrogen-containing-intumescent, and combinations thereof.

5. The composition of claim 1 , wherein the non-halogenated flame retardant is selected from the group consisting of aluminum trihydrate, magnesium dehydrate, hydrotalcite, zinc borate, a phosphorus-nitrogen-containing-intumescent, and combinations thereof.

6. The composition of claim 4 , wherein the dendrimer has a weight average molecular weight of about 2100 g/mole; a polydispersity (Mw/Mn) of about 1.3; a viscosity at 110° C. and 30 secs−1 of about 7 Pascals; and a glass transition temperature (Tg) of 30° C.

7. The composition of claim 1 , wherein the dendrimer has a weight average molecular weight of about 2100 g/mole; a polydispersity (Mw/Mn) of about 1.3; a viscosity at 110° C. and 30 secs−1 of about 7 Pascals; and a glass transition temperature (Tg) of 30° C.

8. The composition of claim 6 , wherein the grafted polyolefin is an the grafted poly(ethylene-co-butene) and maleic anhydride modified polyolefin is maleic anhydride-modified poly(ethylene-co-butene).

9. The composition of claim 1 , wherein the grafted polyolefin is the grafted poly(ethylene-co-butene) and maleic anhydride modified polyolefin is maleic anhydride-modified poly(ethylene-co-butene).

10. A plastic article shaped from the compound of claim 1 .

11. The article of claim 10 , wherein the article is jacketing or insulation for wire or cable.
