Abstract

Nowadays, automobiles industries has become one of the most important industry in the world. The production and consumption of tyres are happening at a larger rate around the world. This contributes to a lot of scrap tyres which does not decomposed easily and pollutes the environment. This research addresses the problem by utilizing valuable scraps and explores the possibility of reducing natural rubber and substituting them with waste tyre derived crumb rubber (WTCR)/Standard Malaysian Rubber (SMR) blends for new application. The aims of this study are to characterize the surface properties of the WTCR by using FTIR and to determine the effect of particle size of WTCR on the surface property. The Fourier Transform Infrared Spectroscopy (FTIR), Thermo-gravimetric Analysis (TGA) and Scanning Electron Microscopy (SEM) of WTCR were used to support the study. The WTCR were prepared with different particle size (400 μm, 40 μm and 75 μm) using sieving analysis. The obtained results from FTIR, TGA and SEM were studied to understand the interaction of WTCR with Standard Malaysian Rubber (SMR). The surface properties of the WTCR were affected by particle size of the samples. The study discovered the finer crumb rubber particles have better adhesion with the SMR.
