Abstract
The present invention relates to: a polyolefin-based resin foam including a polyolefin-based resin and a conductive filler containing carbon nanotubes and carbon black, wherein the weight ratio of the carbon nanotubes to the carbon black is about 1:1.5 to about 1:5; and a molded product produced therefrom. The polyolefin-based resin foam according to the present invention includes the carbon nanotubes and the carbon black in an appropriate ratio, and thus a molded product having good bondability and exhibiting low surface resistance and surface resistance deviation can be produced by molding the same.
Claims9
A polyolefin resin foam comprising:
- about 87 wt % to about 93 wt % of a polyolefin resin;
- and
- about 7 wt % to about 13 wt % of conductive fillers comprising carbon nanotubes and carbon black,
- wherein the carbon nanotubes are present in an amount of about 2 wt % to about 3 wt % based on the total weight of the foam,
- wherein the carbon black is present in an amount of about 5 wt % to about 10 wt % based on the total weight of the foam, and
- wherein the carbon nanotubes and the carbon black are present in a weight ratio of about 1:1.5 to about 1:5.
