Summary: | PURPOSE: A room temperature crosslinkable one-component silicone rubber composition is provided to ensure high fraction rate of filler such as hydrophobic silica, high whiteness, excellent storage stability, mechanical property and rheological property. CONSTITUTION: A room temperature crosslinkable one-component silicone rubber composition comprises hydrophobic silica 0.5-60 wt% and organopolysiloxane 40-99.5 wt% represented by formula 1: ZnSiR3-n-O-[SiR2O]x-SiR3-n-Z'n. The hydrophobic silica has carbon content more than 3.1 weight%, methanol humidity more than 60 %, reflectivity more than 94 %, BET/CTAB ratio more than 1, DBP absorption volume less than 230g/100g, BET surface area of 50-110 m^2/g, and CTAB surface area more than 30 m^2/g. |
