Effect of Crosslink Density on Physical and Mechanical Properties of a Tire Tread Formulation; A General Regression Analysis

The physical and mechanical properties of sulphur cured filled elastomers deeply depend to the density and type of sulphur crosslinks and attachments . In addition of curative levels andtypes, the nature of elastomers and also fillers have a significant effect on crosslinks and consequently on thephysico_mechanical properties of final elastomeric materials. Derivation of the suitable relations between crosslink densityand physico-mechanical properties of rubber is critical and hasbeen investigated via several separate case compounding studies [1-3]. There, the experiment conditions are limited tothe few variables with limited levels. The purpose of this study is to expand the previous observations and to investigatea large number of available experimental data from several separate case studies altogether to study the possibility of derivation of overall rules from a huge number of observations and to develop simple regression models for some properties
