Abstract
A polyolefin composite composition is used in an automotive air duct. The polyolefin composite composition is useful as an automotive air duct component material due to excellent mechanical property, heat resistance, and foaming property as a composition in which a polyethylene resin and a long chain branched polypropylene resin having low crystallization of 45% or less are included as a base resin.
