Thin gauge 12 x 12 inch Silicone Rubber Gasketing for use in fuel cell fixtures.  Like other silicone, 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).

HT6135 Silicon gasketing is a solid silicone elastomer.  Silicone elastomers exhibit a natural shrinkage when the carrier or liner is removed.  Thickness measurements do not include carrier or liner.
