Unformatted text preview: r filler loading, the voids and agglomeration were formed which caused the reduction of tensile strength. POLY-O8 CURE CHARACTERISTICS, TENSILE PROPERTIES AND MORPHOLOGICAL PROPERTIES OF RECYCLED POLYETHYLENE TEREPHTHALATE FILLED NATURAL RUBBER COMPOUNDS Nabil Hayeemasae, H. Ismail and A. A. Rashid School of Materials and Mineral Resources Engineering, Universiti Sains Malaysia, Engineering Campus, 14300 Nibong Tebal, Pulau Pinang, Malaysia E-mail: [email protected] The recycled polyethylene terephthalate (R-PET) was utilized as a filler in natural rubber (SMR L) compounds. The effect of filler concentration range of 0 to 40 phr on cure characteristics, tensile properties, rubber-filler interaction and morphological properties were observed. The results indicated the maximum torque (MH), torque difference (MH -ML), scorch time (ts2) and cure time (t90) of natural rubber compounds were gradually increased with increasing filler loading. This mig ht be associated to the filler related parameter such as high surface area, low moisture content and low metal oxide content. Increment in R-PET gives natural rubber compounds increased the tensile modulus at 100 % strain (M100) and 300 % strain (M300) of natural rubber compounds. Tensile strength and elongation at break showed the decreased trend. The rubber-filler interaction of SMR L increased with increasing RPET loading. This might be due to the poor interaction between R -PET and SMR L. The morphologi cal properties of vulcanizates exhibited the detachment of R-PET particles and more agglomeration was observed with increasing loading of R-PET. 222 3rd ICYC 2010 Universiti Sains Malaysia POLY-O9 23rd-25th June 2010 EFFECT OF SHORT GLASS FIBRE (SGF) CONTENT AND A SILANE COUPLING AGENT ON PROPERTIES OF POLYPROPYLENE/ WASTE TYRE DUST/ SHORT GLASS FIBRE (PP/WTD/SGF) COMPOSITES Z.
