Recycled thermoplastic compositions
View Patent ↗A thermoplastic composition comprising recovered poly(arylene ether), less than or equal to 0.1 weight percent based on the total weight of the thermoplastic composition of a second recovered thermoplastic that gives off greater than or equal to 10 percent by mass of volatiles at a processing temperature for the thermoplastic composition; 0.025 to 4.0 weight percent, based on the total weight of the thermoplastic composition, of a third recovered thermoplastic selected from the group consisting of polyolefin, acrylonitrile-butadiene-styrene, polycarbonate, polycarbonate/acrylonitrile-butadiene-styrene blend, polymethyl methacrylate, polyamide, polyester, polycarbonate/polyester blend and combinations of two or more of the foregoing third recovered thermoplastics, wherein combinations of two or more of the foregoing third recovered thermoplastics are present in an amount of less than or equal to 10 weight percent, based on the total weight of the thermoplastic composition; and an optional virgin thermoplastic.
1. A thermoplastic composition, consisting of:
a recovered poly(arylene ether);
less than or equal to 0.1 weight percent based on the total weight of the thermoplastic composition of a second recovered thermoplastic that gives off greater than or equal to 10 percent by mass of volatiles at a processing temperature for the thermoplastic composition; and
a third recovered thermoplastic selected from the group consisting of polyolefin, acrylonitrile-butadiene-styrene, polycarbonate, polycarbonate/acrylonitrile-butadiene-styrene blend, polymethyl methacrylate, polyester, polycarbonate/polyester blend and combinations thereof, wherein each of the individual foregoing third recovered thermoplastics is present in an amount of 0.025 to 4.0 weight percent, based on the total weight of the thermoplastic composition, and wherein combinations of two or more of the individual foregoing third recovered thermoplastics are present in an amount less than or equal to 10 weight percent, based on the total weight of the thermoplastic composition;
wherein the recovered materials are recovered from end of useful life parts, manufacturing scrap and combinations thereof.
2. The thermoplastic composition of claim 1 , wherein the second recovered thermoplastic is present in an amount of less than or equal to 0.05 weight percent, based on the total weight of the thermoplastic composition.
3. The thermoplastic composition of claim 1 , wherein the second recovered thermoplastic is selected from the group consisting of polyvinyl chloride, polyoxymethylene, polyurethane and combinations of two or more of the foregoing.
4. The thermoplastic composition of claim 1 , wherein the third recovered thermoplastic is present in an amount of 0.1 to 1 weight percent, based on the total weight of the thermoplastic composition.
