Zusammenfassung:	A liquid curable silicone elastomer composition is disclosed. The composition comprises: an organopolysiloxane (A) comprising: an organopolysiloxane (A1) containing at least 2 alkenyl groups bonded to silicon atom per molecule and having a total alkenyl content of from 0.01 to 1.5 mmol/g, and an organopolysiloxane (A2) containing at least 2 alkenyl groups bonded to silicon atom per molecule and having a total alkenyl content of from 5.0 to 15.0 mmol/g; an organopolysiloxane (B) comprising an organopolysiloxane (B1) containing at least 2 silicon-bonded hydrogen atoms per molecule provided by siloxy units of the type (R2HSiO1/2)x where R is independently selected from hydrogen, an aliphatic a hydrocarbyl, an aromatic hydrocarbyl, or an organyl group and x≥2; a platinum based catalyst (C); an inhibitor (D) selected from the group consisting of acetylenic alcohols and their derivatives; and a silica filler (E).
