Thicker gaskets can often seal better on rougher surfaces, but they may also compress more over time. The data sheet will typically list the available thicknesses, allowing you to choose the one that best suits your needs. Consider the surface finish of the mating parts and the amount of compression the gasket will be subjected to when selecting the appropriate thickness. A gasket that is too thin may not seal properly, while one that is too thick may be crushed or extruded.

Temperature range is another critical factor. The data sheet will specify the minimum and maximum operating temperatures for the gasket material. Exceeding these temperature limits can cause the gasket to degrade and fail. Ensure that the temperature range of the flexoid gasket paper is compatible with the operating conditions of your application. For example, if you're using the gasket in an engine, make sure it can withstand the high temperatures generated by the engine. If you're using it in a refrigeration system, make sure it can withstand the low temperatures involved.

Fluid resistance should be carefully evaluated. The data sheet will provide information on the gasket's resistance to various fluids, such as oil, fuel, water, and chemicals. Check the list of fluids and make sure that the gasket is resistant to the fluids it will be exposed to in your application. If the gasket is not resistant to a particular fluid, it may swell, soften, or dissolve, leading to leaks and equipment failure. The data sheet may also provide information on the gasket's permeability, which is a measure of how easily fluids can pass through the material. A lower permeability indicates better fluid resistance.

By carefully reviewing these and other properties listed on the data sheet, you can make an informed decision about whether flexoid gasket paper is the right choice for your sealing needs.
