RTV type silicone rubber - RTV type silicone rubber

…Some dimethyl silicone rubbers have had some of their methyl groups replaced with phenyl groups to improve cold resistance, some with vinyl groups to improve vulcanization speed and reduce compression set, and some with fluoroalkyl groups to improve oil resistance. Silicone rubbers also include liquid rubbers that harden at room temperature, that is, RTV (room temperature vulcanization) type silicone rubbers. These come in one-component and two-component types, both of which have reactive groups at the ends of the rubber molecular chains. The former reacts with moisture in the air, while the latter reacts with both liquid components to extend and crosslink the rubber molecular chains. …

…ジメチルシリコーンゴムのメチル基の一部をフェニル基で置換して耐寒性を向上させたもの,ビニル基で置換して加硫速度の向上や圧縮永久ひずみを減少させたもの,フッ化アルキル基で置換して耐油性を向上させたものなどもある。 シリコーンゴムには室温で硬化する液状ゴム,すなわちRTV(room temperature vulcanization)型シリコーンゴムもある。これには1液型と2液型があり,いずれもゴム分子鎖末端に反応基をもった液状ゴムで,前者は空気中の水分と反応して,後者は両成分液が反応してゴム分子鎖の延長,架橋が行われる。…
