ABSTRACT:
A polyolefin composition is disclosed, which comprises a polyolefin and an inorganic filler, wherein the polyolefin composition comprising (A) 75 to 97% by weight of a polyolefin component comprising (a) 90-65 parts by weight of a polymer composition comprising a crystalline polypropylene component and an ethylene-propylene random copolymer component and having an ethylene content of 7% by weight or less and/or a propylene homopolymer and (b) 10 to 35 parts by weight of a polyethylene having a melt index of not lower than 10 g/10 min., said melt index being from 1.0 to 50 times that of the polymer (a), and (B) 25 to 3% by weight of a fibrous inorganic filler having an average fiber diameter of 0.1 to 0.8 micrometer and an aspect ratio of 20 to 60.
The polyolefin composition is capable of providing, upon molding, articles having good surface appearance, in particular glossiness and improved mechanical strengths with less warping and deformation.
