Preparation and properties of new elastomeric systems containing alternative fillers

Abstract

The present paper deals with a preparation of new elastomeric compounds containing two kinds of alternative additives based on wastes from glass production and energetics. Named alternative fillers were mixed into rubber compounds asa replacement of commonly used fillers – carbon black and silica. Rheological properties, vulcanization characteristics as well as hardness and rebound resilience of vulcanizates, which are important parameters for their industrial application, have been studied in the new prepared elastomeric systems. The resulting vulcanizates containing alternative fillers exhibit improved properties, in particular low rolling resistance and high rebound resilience, while maintaining optimal hardness values. Used raw material substitution can also bring significant environmental and economic effects.
