First, the silver coated aluminum powder was selected as the optimal conductive filler by testing the mechanical strength, elongation ratio, compression set, electronic conductive properties and shielding effectiveness of three silicone rubber with different fillers parallel. Then the volume fraction of silver coated aluminum powder was fixed as 55% through investigating the effect of silver coated aluminum powder content on the mechanical strength, elongation ratio, compression set, micro-morphology and conductive properties of rubbers. Based on the demand of rubber products for long service life, the conductive properties of these rubbers were investigated thoroughly after ageing at environmental temperature and humidity and elevated temperature accelerated testing separately. The result showed that with the ageing time increased, the volume resistivity increased implying electronic conductivity weakened. The volume resistivity was almost not affected after initial 60 days ageing at environmental temperature and humidity, then increased from 4.6×10^-3 Ω·cm to 7.5×10^-2 Ω·cm after 900 days ageing. The volume resistivity increased to 9.5×10^-2 Ω·cm after ageing at 150℃ for 30 days. The result also indicated that the silver coated aluminum powder/silicone rubber can retain the electronic conductive properties after ageing at two conditions. The ageing effect of elevated temperature accelerated testing was more significant than natural storage ageing.
