| titleOfInvention | Long-fiberglass reinforced polyolefin moldings improved in weathering resistance and compositions useful as the raw material therefor |
| abstract | The long-fiberglass reinforced polyolefin moldings according to the prior art were poor in weathering resistance, though excellent in mechanical strengths. They were also liable to lower in the mechanical characteristics when they contained colorants. The present invention provides long-fiberglass reinforced polyolefin moldings excellent in both weathering resistance and mechanical strengths, compositons useful as the raw material therefor, and further moldings which are not impaired in either of the above properties even when they are colored and compositions useful as the raw material therefor. Specifically, the compositions at least comprise (A) long-fiberglass reinforced polyolefin pellets which are produced by impregnating a glass fiber roving with a polyolefin and cutting the resulting roving in lengths of 2 to 150 mm and have a fiberglass content of 10 to 90 wt.% and wherein the glass fibers contained are arranged in a length substantially equal to that of the pellet, (B) a light stabilizer and (C) a light absorber, and are characterized in that the total amount of the components (B) and (C) is 0.25 to 7.5 parts by weight per 100 parts by weight of the whole polyolefin; and long-fiberglass reinforced polyolefin moldings at least comprising (a) a polyolefin, (b) a fiberglass having a fiber length of 2 to 150 mm, (B) a light stabilizer and (C) a light absorber, characterized in that the total amount of the component (B) and (C) is 0.25 to 7.5 parts by weight per 100 parts by weight of the whole polyolefin and that the fiberglass content is 10 to 90 wt.%. The above moldings can keep both of the above properties at high levels even when colored black with carbon black or gray with carbon black and zinc sulfide, as far as the colorant(s) is added at a specific ratio to the above additives. |
