my.unimap-351582014-06-06T09:43:44Z 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. hakimah@unimap.edu.my hanafi@eng.usm.my azlan@eng.usm.my Curing characteristics Feldspar Mechanical properties Natural rubber Swelling behaviour Link to publisher's homepage at http://www.tandfonline.com/ 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 time, (t2) and cure time, (t90) of both rubber vulcanizates slightly increased with increasing feldspar loading. At a similar feldspar loading, the ENR 50 vulcanizates showed shorter t2 and t90 than SMR L vulcanizates. Besides t2 and t90, maximum torque, (MHR) and torque difference (MHR - ML) were also investigated. Results indicate that MHR and MHR - ML increase for both rubbers with increasing feldsparloading. Swelling test results showed a reduction in the swelling percentage for both rubbers with increasing feldspar loading. At a similar filler loading, SMR L vulcanizates showed lower swelling percentage than ENR 50 vulcanizates. The mechanical properties such as tensile strength (up to certain filler loading), tensile modulus and hardness increased with increasing feld-spar loading for both rubbers. However, at a similar feldspar loading, the mechanical properties of SMR L vulcanizates are higher than ENR 50 vulcanizates. 2014-06-06T09:43:44Z 2014-06-06T09:43:44Z 2005 Article International Journal of Polymeric Materials and Polymeric Biomaterials, vol.54(1), 2005, pages 43-62 0091-4037 http://www.tandfonline.com/doi/abs/10.1080/.U5GG_YaQZYY http://dspace.unimap.edu.my:80/dspace/handle/123456789/35158 10.1080/00914030390245929 en Taylor and Francis Inc. |
