| Claim: |
1. A method of preparing a foamed gasket, comprising: providing a foam having a density in the range of 0.005 to 0.6 g/cm3; molding the foam into foam sheets; and forming the gasket from the foam sheets. |
| Claim: |
2. The method of claim 1, wherein a polymer or polymers used to make the foam do not contain any functional groups which can be hydrolyzed. |
| Claim: |
3. The method of claim 1, wherein the foam is a compressible foam or a rigid non-compressible foam. |
| Claim: |
4. The method of claim 3, wherein the density of the compressible foam is between 0.05 to 0.25 g/cm3. |
| Claim: |
5. The method of claim 3, wherein the compressible foam can be compressed without inherent material failure by external applied force or mechanical load greater than or equal to 5% in the axis of applied force or mechanical load. |
| Claim: |
6. The method of claim 3, wherein the compressible foam has an open-celled structure or a close-celled structure. |
| Claim: |
7. The method of claim 6, wherein the surface of the compressible foam having an open-celled structure is covered with a skin layer which prevents fluids from entering the open-celled structure. |
| Claim: |
8. The method of claim 3, wherein the density of the rigid non-compressible foam is between 0.02 to 0.2 g/cm3. |
| Claim: |
9. The method of claim 3, wherein the rigid non-compressible foam has an open-celled structure or a close-celled structure. |
| Claim: |
10. The method of claim 9, wherein the surface of the rigid non-compressible foam having an open-celled structure is covered with a skin layer which prevents fluids from entering the open-celled structure. |
| Claim: |
11. A foamed gasket used in the photovoltaic module, comprising: a foam having a density in the range of 0.005 to 0.6 g/cm3. |
| Claim: |
12. The gasket of claim 11, wherein a polymer or polymers used to make the foam do not contain any functional groups which can be hydrolyzed. |
| Claim: |
13. The gasket of claim 11, wherein the foam is a compressible foam or a rigid non-compressible foam. |
| Claim: |
14. The gasket of claim 13, wherein the density of the compressible foam is between 0.05 to 0.25 g/cm3. |
| Claim: |
15. The gasket of claim 13, wherein the compressible foam can be compressed without inherent material failure by external applied force or mechanical load by greater than or equal to 5% in the axis of applied force or mechanical load. |
| Claim: |
16. The gasket of claim 13, wherein the compressible foam has an open-celled structure or a close-celled structure. |
| Claim: |
17. The gasket of claim 16, wherein the surface of the compressible foam having an open-celled structure is covered with a skin layer which prevents fluids from entering the open-celled structure. |
| Claim: |
18. The gasket of claim 13, wherein the density of the rigid non-compressible foam is between 0.02 to 0.2 g/cm3. |
| Claim: |
19. The gasket of claim 13, wherein the rigid non-compressible foam has an open-celled structure or a close-celled structure. |
| Claim: |
20. The gasket of claim 19, wherein the surface of the rigid non-compressible foam having an open-celled structure is covered with a skin layer which prevents fluids from entering the open-celled structure. |
