Multicomponent system containing a thermoplastic and a rubber component, e.g. for use in cylinder head seals or rollers, contains at least two peroxide cross-linkers with different 1-hour decomposition temperatures

摘要

A multi-component system (I) containing (1) a thermoplastic component and (2) a rubber component, in which (2) comprises (a) peroxide-vulcanisable elastomer(s) in amounts of 30 wt% or more based on all elastomers in (2) and (b) two or more peroxide crosslinkers, one with a decomposition temperature T1/2 (1 hour) of 70-130[deg]C (b1) and at least one other with a T1/2 (1 hour) of 120-160[deg]C (b2), the difference in T1/2 between them being at least 5[deg]C.
