HIGHLY FILLED COMPOSITES WITH THERMOPLASTIC ELASTOMERS MATRIX

The mechanical and rheological properties of blends based on commercia l types of thermoplastic elastomers (TPEs) Finaprene with polystyrene and ethylene-vinylacetate copolymer, used as suitable materials to pro duce highly filled composites with magnetically hard fillers, have bee n investigated. The influence of a 90% to 93% filler content and the m orphology of the fillers on mechanical, rheological, and magnetic prop erties of composites is discussed. The influence of changes of other t echnological parameters, such as type of treatment of the fillers and type of mixer, on properties of composites has been studied.
