A polypropylene composite that includes 50 to 75 weight percent of
polypropylene resin based on the weight of the polypropylene composite.
The polypropylene resin has a melt flow rate of from 20 to 300 at
230.degree. centigrade under a 2.16 kilogram load. The polypropylene
composite also includes from 5 to 15 weight percent based on the weight
of the polypropylene composite of ethylene-alpha-olefin diene copolymer
rubber. The ethylene-alpha-olefin diene copolymer rubber has a melt flow
rate of less than 0.4 at 230.degree. centigrade under a 2.16 kilogram
load. Also included is from 5 to 15 weight percent of an
ethylene-alpha-octene copolymer rubber having a melt flow rate of from
0.5 to 20 at 230.degree. centigrade under a 2.16 kilogram load Also a
ratio of ethylene-alpha-olefin diene copolymer rubber divided by a total
content of ethylene-alpha-olefin diene copolymer rubber and
ethylene-alpha-octene copolymer rubber is 0.35-0.45. Also included is
from 20 to 25 weight percent based on the weight of the polypropylene
composite of organic filler. Further included is from 0.1 to 5 weight
percent based on the weight of the polypropylene composite of a grafted
polypropylene and from 0.1 to 0.6 weight percent based on the weight of
the polypropylene composite of a surface treatment material. The surface
treatment material remains dispersed in the polypropylene composite
preventing blooming of the surface treatment material when exposed to the
environment.
