Compound Design Considerations with Silica Masterbatch for Various Tread Performance Requirements
In this presentation we will vary the elements of Emulsil® silica masterbatch products based on specific tread performance properties. Compound design considerations with latex type and silica surface area, will be selected based on the tread’s key property requirements. Examples of all-season tread formulations will be reviewed, and the analysis of critical compound properties based on physical and dynamic data will be covered. The correlation of these with key tread performance properties such as wear, rolling-resistance, wet/dry traction and ice traction will be discussed.
Furthermore, an introduction of Dynasol’s newly developed silica masterbatch technology using solution SBR polymer will be presented. Compounding evaluations with resultant data using a standard PCR (passenger car radial) tread formulation will be reviewed to show silica masterbatch technology advantages.
