The article deals with the preparation and evaluation of EPDM blends used in the automotive industry. In order to reduce the conductivity of the EPDM blend, the formula composition of the blend was modified. The carbon black content was reduced and basic types of rubber mineral fillers (Sillitin Z 86, Talc, Mistron R 10C, Omyacarb 2 VA) and newly developed types of white fillers (WERBALINK® KK 20 R, MPK-2, VPK 76, IL) were added into rubber compounds. The prepared EPDM blends were submitted to measurements of Mooney viscosity, vulcanizing characteristics (M_H, M_L, t₁₀, t₉₀), mechanical and physical properties (tensile strength, elongation at break, hardness) as well as surface and volume resistivity. The obtained results were compared to values of reference model blend with addition of Sillitin N 85 filler. The processing performance of the EPDM blends were studied by Garvey die extrusion. The compression set of the EPDM blends was tested, too.
