Silicone elastomer, composition, and optical coupling element

1. An optical coupling element, comprising:

a molded silicone elastomer comprising a plasticizer component formed by or containing oil or an oil blend, wherein the oil or at least one oil of the oil blend has a viscosity that is equal to or less than 350 mm 2 /s, and/or being produced out of a composition comprising a silicone rubber component, a cross-linking component, a cross-linking catalyst and the plasticizer component, the silicone elastomer being capable of being manually handled, wherein the optical coupling element is arranged between a sensor and the inside of a vehicle window pane.

2. The optical coupling element according to claim 1 , wherein the oil or the at least one oil of the oil blend is a silicone oil.

3. The optical coupling element according to claim 1 , wherein the percentage by weight of the plasticizer component is at least 20% of the total weight of the silicone elastomer.

4. The optical coupling element according to claim 1 , wherein the silicone elastomer is produced out of the composition comprising the silicone rubber component, the cross-linking component, the cross-linking catalyst and the plasticizer component.

5. The optical coupling element according to claim 4 , wherein the plasticizer component is or contains a silicone oil.

6. The optical coupling element according to claim 4 , wherein the percentage by weight of the plasticizer component is at least 20% of the total weight of the composition.

7. The optical coupling element according to claim 1 , wherein the silicone elastomer does not flow at room temperature.

8. The optical coupling element according to claim 1 , wherein the silicone elastomer exhibits no bleeding at a temperature of 105° C.
