Article including a weld line based on a mixture of polyamide and polyolefin

摘要：

The invention relates to an article based on a mixture of polyamide and polyolefin, which article includes at least one weld line due to multi-port injection molding, said article characterized in that the ratio of the viscosities of the polyolefin to the polyamide, measured at a shear rate higher than 100 s−1, is greater than 0.70, and that the quantity of polyamide is sufficient for the elongation at break to be greater than 10%. A typical application is the production of an injection molded automobile fender.

摘要（中）：

本发明涉及一种基于聚酰胺和聚烯烃的混合物的制品，该制品由于多端口注射成型而包括至少一条熔接线，所述制品的特征在于聚烯烃与聚酰胺的粘度比在高于100s-1的剪切速率大于0.70，聚酰胺的量足以使断裂伸长率大于10％。典型的应用是生产注塑汽车挡泥板。
