Hakimah, Osman, Dr.; Azlan, Ariffin; Hanafi, Ismail, Prof. Dr. (Taylor Francis Inc, 2005)Comparison studies on effects of feldspar and silica (Vulcasil C) as a filler in (SMR L grade natural rubber) vulcanizates on curing characteristics, mechanical properties, swelling behavior, thermal analysis, and morphology ... -
Curing characteristics, fatigue and hysteresis behaviour of feldspar filled natural rubber vulcanizates
Hakimah, Osman, Dr.; Hanafi, Ismail, Prof. Dr.; Azlan, Ariffin (Taylor and Francis Inc., 2007)Curing characteristics, fatigue, and hysteresis behaviour of feldspar filled SMR L vulcanizates and feldspar filled ENR 50 vulcanizates were studied. Two different types of natural rubber, SMR L and ENR 50 having 0 and 50 ... -
The effect of feldspar loading on curing characteristics, mechanical properties, swelling behaviour and morphology of natural rubber vulcanizates
Hakimah, Osman, Dr.; Azlan, Ariffin; Hanafi, Ismail, Prof. Dr. (Taylor and Francis Inc., 2005)Feldspar is being used herein as a filler in natural rubber vulcanizates. Two different types of natural rubber, SMR L and ENR 50 having 0 and 50 mol% of epoxide groups and semi-efficient vulcanization were used. The scorch ... -
Effects of maleic anhydride polypropylene on tensile, water absorption, and morphological properties of recycled newspaper filled polypropylene/natural rubber composites
Hakimah, Osman, Dr.; Hanafi, Ismail; Mariatti, Mustapha, Prof. Ir. (SAGE Publications, 2010)This study focused on the effects of maleic anhydride-grafted polypropylene (MAPP) on tensile, water absorption, and morphological properties of recycled newspaper (RNP) filled polypropylene (PP)/natural rubber (NR) ... -
Effects of natural weathering on properties of recycled newspaper-filled polypropylene (PP)/natural rubber (NR) composites
Hakimah, Osman, Dr.; Mariatti, Jaafar, Assoc. Prof. Dr.; Hanafi, Ismail. Prof. (Taylor & Francis, 2008)Natural weathering has been applied to investigate the properties of recycled newspaper (RNP)-filled polypropylene (PP)/natural rubber (NR) composites. Three sizes of RNP (11 mm, 23 mm, and 53 mm) were used in this study. ... -
