Thin gauge 12 x 12 inch Silicon Rubber Gaskets for use in fuel cell fixtures. Like other silicon, this rubber stays flexible over a wide temperature range, but its softness gives it better conformability than other rubber. A peel-off protective masking keeps this rubber free from dust and debris. Width and length tolerances are ±1/4″. Durometer tolerance is ±5.

Teflon and fiberglass reinforced Teflon are used in high temperature applications such as High Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) and Phosphoric Acid Fuel Cells (PAFC).
