Wiper rubber with cross-linked base body and sliding body

The invention relates to a method for producing a wiper rubber (10), in particular for a windscreen wiper, in which a first material (11 *) for a base body (11) of the wiper rubber (10) and a second material (12 *) for at least one sliding body (12) are co-extruded and/or injected and/or cast into a...

Beschreibung
Zusammenfassung:	The invention relates to a method for producing a wiper rubber (10), in particular for a windscreen wiper, in which a first material (11 ) for a base body (11) of the wiper rubber (10) and a second material (12 ) for at least one sliding body (12) are co-extruded and/or injected and/or cast into a base body-sliding body strip (100), the at least one sliding body (12) covers a part of the surface of the main body (11), which part defines a wiper contact for the wiper rubber (10). The first material (11 ) and the second material (12 ) each comprise at least one crosslinkable polymer. In order to provide a wiper rubber in a simple, cost-effective and environmentally friendly manner, the wiper quality of which can be maintained over a long period of time, the second material (12 ) comprises at least one crosslinking agent for crosslinking the material, at least one crosslinkable polymer of the second material (12 ) and at least one crosslinkable polymer of the first material (11 *) are used for crosslinking
