Abstract
Disclosed is a thermoplastic polyolefin (TPO) nanocomposite composition, more particularly a TPO nanocomposite composition including a polypropylene resin, a polyethylene resin, a rubber resin, a nanoclay master batch and a glass bubble master batch. Since the disclosed TPO nanocomposite composition has low specific gravity and superior gloss reducing effect and scratch resistance, it may be usefully applied to light automobile parts, uncoated automobile exterior parts, or the like.

A thermoplastic polyolefin (TPO) nanocomposite composition comprising a polypropylene resin, a polyethylene resin, a rubber resin, a nanoclay master batch and a glass bubble master batch,
- wherein the nanoclay master batch comprises:
- 20 to 30 wt % of maleic anhydride grafted polypropylene;
- 30 to 50 wt % of nanoclay;
- and
- 30 to 40 wt % of polyethylene-propylene copolymer.
A thermoplastic polyolefin (TPO) nanocomposite composition comprising a polypropylene resin in an amount of 30 to 60 wt % based on total weight of the composition, a polyethylene resin in an amount of 1 to 10 wt % based on total weight of the composition, a rubber resin in an amount of 10 to 40 wt % based on total weight of the composition, a nanoclay master batch in an amount of 10 to 30 wt % based on total weight of the composition and a glass bubble master batch,
- wherein the nanoclay master batch comprises (i) 20 to 30 wt % of maleic anhydride grafted polypropylene;
- (ii) 30 to 50 wt % of nanoclay;
- and (iii) 30 to 40 wt % of polyethylene-propylene copolymer.
