Training Document – Rubber Reinforcement with Carbon Black & Silica
(2 July 2019, Kuala Lumpur, Malaysia)
This document has presentation slides of this training program. Dr. Robert Schuster, World-Renowned Rubber Technologist is the trainer. The book is spiral-bound format with colored print of all presentation slides.

The training is designed to provide an overview on filler reinforcement by Carbon Black and Silica/Silane in tire formulations and technical rubber goods. The advantages and disadvantages of both technologies will be presented. With the implementation of silica in the tire technology (green tire) the tread properties have been successfully improved with respect to rolling resistance and wet grip. This leads directly to significant reductions of fuel consumption and safe driving at higher speed. Details about silanization with different silanes (mono- and difunctional) under different mixing conditions and temperature regime, the degree of silanization, the impact on silica dispersion and dynamic mechanical as well as ultimate properties will be presented. However, recent developments demonstrate that optimal dispersion of CB leads to similar performance and in addition a very substantial improvement of abrasion resistance. The key-parameter for this success is a properly designed filler surface activity and filler – polymer interaction. Key parameters to improve the processing parameters of rubber compounds as well as the final material properties are presented. The factors that lead to the required nano-dispersion of the reinforcing fillers will be discussed for the two different filler systems. In addition the problem of filler transfer and phase distribution of CB and polar precipitated silica in non-polar rubber blends (BR/SBR and BR/SBR/NR) will be an important part of the Seminar. This course outline includes:
• Manufacturing of Carbon Black and Silica • Characterization of Filler Particles • Surface Specific Area and Structure • Surface Activity • Incorporation and Dispersion of CB and Silica • Flocculation of filled Compounds • Methods to measure Dispersion • Technical Mixing Procedures • Special Features of Silica/Silane Technology • Properties of uncured filled Compounds • Properties of cured filled Compounds • Fracture Mechanical Features • Functional Polymers for better Dispersion • New Developments
