The present disclosure provides an elastomer composition, comprising, based on the total weight 100 wt.% of the elastomer composition: 1-50 wt.% of a modified ethylene propylene copolymer; 5-60 wt.% of a first silicone resin, the first silicone resin comprising at least one selected from the group consisting of the following: a hydroxyl-terminated silicone resin and an alkoxy-terminated silicone resin; 0.1-15 wt.% of a first crosslinking agent; 0.1-15 wt.% of a catalyst; and 10-85 wt.% of a filler. The elastomer composition provided by the present disclosure at least can be co-crosslinked in low temperature (approximately -20°C to 60°C) conditions. An elastomer prepared from the elastomer composition provided by the present disclosure has good mechanical properties and electrical insulation properties.
