Abstract

See full text

Microspherical fillers are used to increase the scratch resistance of thermoplastic vulcanizates in extruded profiles while providing aesthetically attractive surface effects. The thermoplastic vulcanizates comprise a thermoplastic phase and a rubber that is at least partially cross-linked by dynamic vulcanization. The fillers can be added by melt blending with the pre-formed thermoplastic vulcanizate. An attractive, granite-like appearance can be achieved with enhanced scratch resistance that is particularly suitable as automotive interior or exterior trim parts.
