| 摘要 |
The present invention relates to a thermoplastic composition for overmolding an elastomer onto a mineral glass substrate. Said composition includes: (a) 50 to 70 wt% of at least one thermoplastic elastomer (TPE) selected from among styrenic block copolymers (TPE-S); (b) 20 to 35 wt%, preferably 22 to 30 wt%, of a polyolefin selected from among propylene homopolymers (PP), ethylene homopolymers (PE), and propylene and ethylene copolymers; and (c) at least 7 wt%, preferably 8 to 20 wt%, and particularly 9 to 15 wt%, of a functional alcoxysilane. The percentages are expressed in relation to the sum of the components (a), (b), and (c). The invention also relates to a method for injection overmolding or extrusion overmolding one such composition onto a substrate, preferably a glass panel for an automobile. |
