Abstract:
1. A process for producing a composite molded part, comprising the steps of applying at least one addition-crosslinking silicone rubber mixture onto at least one polyarylene sulfide substrate by injection molding, coextrusion, casting, or calendering, followed by the steps of heating and pressing, wherein the silicone rubber is applied as a mixture comprising the following components: a) 100 parts of at least one linear or branched organopolysiloxane containing alkenyl groups and having at least 2 alkenyl groups, with a viscosity of from 0.01 to 30,000 Pas; b) at least one hydrosiloxane having at least two SiH functions per molecule in an amount such that the molar ratio of the SiH group to the total amount of Si-bonded alkenyl groups is at least 1.5; c) at least one Pt catalyst or Rh catalyst; and d) from 0.1 to 10 parts of at least one alkoxysilane having at least one epoxy group and/or alkoxysiloxane having at least one epoxy group.
