Abstract

Claims (12)

1. An elastomeric material crosslinkable by sulphur compounds and comprising approximately 50 to 99.5 percent by weight of a polysiloxane based on a total polymer content as a main polymer ingredient, and at least 0.5 percent by weight of an unsaturated polymer, based on the total polymer content, wherein the material is expanded to a final density of less than about 200 kg/m 3 .

2. The material according to claim 1 , wherein the unsaturated polymer comprises an alkylene-diene copolymer.

3. The material according to claim 1 , wherein the polysiloxane comprises a vinyl content of at least 0.5 mol percent.

4. The material according to claim 1 and further comprising fillers and additives.

5. The material according to claim 4 , wherein the elastomeric material is vulcanized and expanded.

6. The material according to claim 5 , wherein the elastomeric material is expanded to a foam with mainly closed cells.

7. A process for manufacturing the material according to claim 1 , comprising a one-step mixing process and a one-step shaping process.

8. A method for providing acoustic or thermal protection to a surface, the method comprising a material according to claim 1 to the surface.

9. A. method for providing temperature or noise protection to a surface, comprising applying a material according to claim 1 to the surface.

10. A method for treatment, comprising applying a material according to claim 1 to a structure so as to affect at least one of thermal insulation, acoustic insulation, acoustic damping, or vibration damping, of said structure.

11. A method for thermal shielding, comprising applying a material according to claim 1 to inside and outside of structures, vessels, containers, pipes, walls, tanks, tubes, or ducts.

12. The material according to claim 1 , wherein the elastomeric material is expanded to a final density of less than about 150 kg/m 3 .
