Biography

Development & Testing of Silicone Rubber Filled Synthetic Wollastonite Dielectric Composite for HV Applications

Dr. Razak received his PhD in Materials Science from National University of Malaysia. His research interests are on polymer & rubber blends, dielectric & conductive polymeric composites and polymer based nanocomposites. He is a Chartered Engineer with Engineering Council (EC), UK and appointed as Professional Technologist in nanotechnology. Presently, he serves as Sr. Lecturer at the Faculty of Manufacturing Engineering and is active in consultation and research in engineering materials design, testing and optimization.

Silicone rubber has become widely used in outdoor insulation due to intrinsic properties of flexibility, hydrophobicity, chemical, thermal and UV resistance, etc. but has the limitation of lower stiffness. Relative performance of different SiR-based composites is influenced by dispersion of added filler while type of filler, amount of filler loading, filler size and treatment all influence properites such as resistance to tracking and erosion. Fillers include alumina tri-hydrate, silica, calcium carbonate and others while certain mineral fillers also allow for better surface hydrophobicity. This presentation reviews research, development and testing of SiR-filled CaSiO3 composites for HV insulation applications.
