TRANSFER OF METHODS FOR DETERMINING THE VULCANIZATION CHARACTERISTICS OF ELASTOMER COMPOSITIONS

Abstract. Methods and standards of main rheokinetic parameters of elastomeric compounds vulcanization process are characterized in the paper, including international standard ASTM DIN 53529, which is successfully applied for solving tire production problems at “Rosava Tires”, Bila Tserkva. According to the experimental data taken by the vibrorheometer of rotorlesstype MDR 3000 Professional of the company MonTech Werkstoffprufmaschinen GmbH, a correlation was established between the characteristics of the isotherms of the elastomeric compositions based on non-stereoregular butadiene-α-methylstyrene rubber (at presence technological active additives), according to the ASTM DIN 53529 standard and according to other methods. The features of the selection of four parameters are shown, which are taken into account with the help of MonControl analytical security.

Keywords: vulcanization, vulcametry, elastomeric compositions, characteristics of crosslinking isotherms, correlation.
