Silicone rubber and EPDM micro composites filled with silica and ATH

Role of polymer‐filler interaction on Mg(OH)2 and alumina trihydrate‐loaded ethylene propylene diene monomer based polymer composite for high voltage insulation application

“…4,5 Therefore, fillers are added in order to improve the dielectric, thermo-mechanical and weathering properties of the polymeric insulators. 6,7 Alumina trihydrates (ATH) and silica are the most common reinforcing fillers used in the synthesis of polymer composites for high voltage electrical insulator application. 8,9 Filler shape, size, molecular interaction with matrix phase and its dispersion in the base polymer matrix are known to have a major impact on the performance of the insulator.…”

“…18 Isaías Ramírez et al have observed that EPDM/ ATH composite shows better resistant to erosion as compared to SiR/ATH composite. 6 Lu et al have reported that the use of magnesium hydroxide increases the mechanical characteristics and thermal stability of vulcanized rubber by improving interaction between filler and polymer matrix. 19 Shorab et al shows a significant improvement in the dielectric, thermal, mechanical and hydrophobic properties of EPDM composite by loading micron sized inorganic TiO 2.…”

“…20 Various studies reveal that ATH and silica filler has improved the dielectric and mechanical properties of EPDM and PDMS composite. 6,15,21 Since, the literature is devoid of ample work related to EPDM based polymer composite for high voltage insulation application; there is a need to explore the structureproperty correlation between EPDM and various fillers and its effect on high voltage insulation properties. Moreover, Mg(OH) 2 loaded EPDM composites have not been evaluated for its performance in high voltage outdoor application.…”

Investigation of Electrical Properties of TiO2 Nanocomposite Based Polymer

“…Ceramic insulators have been used over 100 years show great insulation performance in terms of lifespan and ageing [1,3] and acquiring high resistance and mechanical strength. However, this insulator Since the 1970s, two common polymer materials are being used in outdoor insulation, silicone rubber (SiR) and ethylene propylene diene (EPDM) rubber [4] [5]. SiR had been widely used due to its great electrical performance and equipped with good hydrophobic properties and strong mechanical strength [1].…”

“…Even both materials show enormous advantages, EPDM and silicone rubber still experience high electrical field stresses at both end fittings of insulator, high voltage and ground terminals. Because of such situation, a number of research have been conducted to modify their original properties by compounding this material with fillers or additives in order to improve their electrical and mechanical properties [4][5][6][7][8][9]. Fillers or additives have been used for a few decades particularly in biomedical, marine industry etc.…”
